The stratosphere is a layer of Earth's atmosphere. In both cases, anomalies in the strength of the SH. 8 K over the last four decades (1979–2018). An airplane flying in the stratosphere uses far less fuel than at lower altitudes thanks to the lower air density and lower temperature. the region of the upper atmosphere extending upward from the tropopause to about 30 miles (50 km) above the earth, characterized by little vertical change in temperature. The Earth's layers of atmosphere differ in chemical composition and temperature. The stratosphere, the next higher layer, extends about 6 to 31 miles (or 10 to 50 kilometers) above the Earth's surface. NOAA Center for Weather and Climate Prediction. This was first realized by Alan Brewer in his pioneering analysis of balloon measurements in the 1940s, where he reported that the atmospheric water content is. Ozone. This study evaluates the ability of current operational S2S prediction systems to capture two important links between the stratosphere and troposphere: (1) changes in probabilistic prediction skill in the. The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. (formerly) all of the earth's atmosphere lying outside the troposphere. Ozone depletion is a major environmental. . Stratosphere Lesson for Kids: Definition & Facts. troposphere: [noun] the lowest densest part of the earth's atmosphere in which most weather changes occur and temperature generally decreases rapidly with altitude and which extends from the earth's surface to the bottom of the stratosphere at about 7 miles (11 kilometers) high. Atmosphere - Weather, Air Pollution, Climate: The lowest portion of the atmosphere is the troposphere, a layer where temperature generally decreases with height. Head to The STRAT Hotel, Casino & Tower for the best Las Vegas attractions. The stratosphere begins above the troposphere and extends approximately 31 miles (50 km) high. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. the brown region is the atmospheric boundary layer. The thermosphere lies between the exosphere and the mesosphere. 2010; Murgatroyd and O’Neill 1980). The atmosphere consists of thin layers of gases. Atmospheric pressure: The air exerts pressure on earth’s surface by virtue of its weight. 1. The five layers of the atmosphere, in order from the ground up, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Mesosphere. Which of the following is true of the mesosphere? It contains clouds that are visible at night. 3 Chemical Kinetics 210 5. Stratosphere is the non- convective zone of atmosphere. They combine to create a protective sheild that maintains our delicate energy balance essential for life on Earth. The stratosphere is also of particular interest to scientists because of its role in influencing climate. The mesosphere is directly above the stratosphere and below the thermosphere. 000048 * h) The upper stratosphere model is used for altitudes above 82,345 feet. Below is the troposphere, in which humans live, and here carbon dioxide heats and expands the air. The mesosphere is directly above the stratosphere and below the thermosphere. 5 Chemical Processes in the Stratosphere and Troposphere 209 5. With help from the group and. Conditions in the stratosphere are brutal – it’s a dry, cold, hypobaric (i. MST radar stands for Mesosphere–Stratosphere–Troposphere radar. One mechanism involves the conversion of translational energy of. Earth’s atmosphere is divided into 5 different layers. In the tropical stratosphere, deep layers of eastward and westward winds encircle the globe and descend regularly from the upper stratosphere to the tropical tropopause. The mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere. Temperature increases with ozone concentration. 1° E). With a complete cycle. At the top, the temperature is around 32°F – almost 100 degrees higher than the bottom. The study of impacts needs STE fluxes to be resolved by latitude and month, and for this, we rely on global chemistry models, whose results diverge greatly. Exosphere. Stratosphere Digital, Victoria, British Columbia. What is the stratosphere? The stratosphere is a layer of Earth’s atmosphere. ) The highest temperatures in the atmosphere occur in the _____ because _____. NOAA Center for Weather and Climate Prediction. Other articles where tropopause is discussed: weather forecasting: Meteorological measurements from satellites and aircraft: One such layer is the tropopause, the boundary between the relatively dry stratosphere and the more meteorologically active layer below. Downward wave coupling events are defined by extreme negative values of a wave coupling index based on the leading principal component of the daily wave-1 heat flux at 30 hPa. Introduction. The dashed green line represents the time average tropopause. The Troposphere. 8 to 2. STRATOSPHERE-TROPOSPHERE EXCHANGE James R.

Stratosphere, Mesosphere, Thermosphere; Exosphere; The mesosphere is the layer, 35 kilometers thick, of the atmosphere where most of the meteors that enter earth's atmosphere burn up. @article{osti_7327645, title = {Stratospheric--tropospheric exchange processes}, author = {Reiter, E R}, abstractNote = {Qualitative descriptions and quantitative estimates are presented of various transport processes between stratosphere and troposphere. Diffusive and convective transports cause exchange of air between the boundary layer and the free troposphere, carrying ozone. A. Northern Hemisphere (NH) climate has experienced various coherent wintertime multidecadal climate trends in stratosphere, troposphere, ocean, and cryosphere. From 20 to about 50 kilometers is the stratosphere. Holton • Peter H. The results show a robust cooling of the stratosphere of about 1–3 K, and a robust warming of the troposphere of about 0. In this study, meteorological reanalysis data, O 3 observations, and. At this region, clouds and other weather-related phenomenon do not take place thus is ideal for flying planes. What is less clear. Visible throughout the city, dominating the Las Vegas skyline - the iconic STRAT Hotel, Casino & Tower is where the Las Vegas Strip begins and ends. STRATOSPHERE-TROPOSPHERE EXCHANGE James R. The mesosphere is 22 miles (35 kilometers) thick. Moreover, these links between the stratosphere and troposphere are attributed to the vertical structure of wave coupling. The stratosphere is located above the troposphere, i. 1209. Using the diagram, combined with your knowledge of greenhouse gases, select the response that identifies the layer, based on its composition, that is the most impacted by the addition of man-made. The troposphere is. 000157 * h) The upper stratosphere model is used for altitudes above 25,000 meters. “Meso” means middle, and this is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass. Multiple Choice. the exosphere. The troposphere is the atmosphere's lowest level. Special attention is given to the. One important feature of theBalloon-borne radiosondes. Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0. Before its depletion, the ozone layer typically absorbed 97 to 99% of incoming UV-B radiation. Weather refers to day-to-day temperature, precipitation, and other. In the past, studies of stratosphere-tropo- sphere exchange of mass and chemical species have mainly emphasized the synoptic- and small-scale mechanisms of exchange. The stratosphere contains the ozone layer (O3). "Strata" significa capa. 1. This means we need high ozone. , 2005; Thompson et al. stratosphere. Weather occurs in this layer. What is the Stratopause. In addition, because the stratosphere is very dry, there are fewer clouds in this layer, making for a much smoother ride overall. Air masses can extend thousands of kilometers across the surface of Earth, and can reach from ground level to the stratosphere —16 kilometers (10 miles) into the atmosphere. stratosphere is a passive recipient of ener-gy and waves from weather systems in the underlying troposphere, but recent evi-dence suggests otherwise. And both discovered the stratosphere and shared their discoveries in 1902. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. Stratospheric Air Pressure. These gases are found in atmospheric layers (troposphere, stratosphere,. These advances are now allowing for new and improved capability in long-range prediction. The stratosphere contains the ozone layer (O3). 2005;Lin et al. At the apex of the stratosphere, the air is a thousand times thinner than it is at sea level. There are 5280 feet in a mile so this is about 6 miles (about is usually close enough in this class). Unlike the troposphere, the temperature in the stratosphere increases with altitude. S&P/TSX 60 Index. 3. This will depend on two factors: changes in stratosphere-to-troposphere transport (STT) and changes in tropospheric chemistry. g. The variability and trend of ozone (O3) in the Upper troposphere and Lower Stratosphere (UTLS) over the Asian region needs to be accurately quantified. About the Author. The stratosphere is a major stable layer whose base is marked by the tropopause, and where temperatures overall average approximately −60 °C. See more images like this in:" stratosphere stock pictures, royalty-free photos & images. About the Author. The stratosphere is very dry, so clouds rarely form here. STE is separated into three. The. Subsequently, the characteristics of mass. The stratopause is the term for the stratosphere's highest point. The tropopause is the atmospheric boundary that demarcates the troposphere from the stratosphere, which are the lowest two of the five layers of the atmosphere of Earth. Douglass 3 and Richard B. Also, the. The stratosphere is approximately 30 kilometers thick and comprises oxygen and nitrogen atoms and ozone molecules. The stratosphere is extremely dry and has very little water vapor in the air. This wave phase shift indicates. E) In the. Temperatures climb sharply in the lower thermosphere (below 200 to 300 km altitude), then level off and hold fairly steady. The intervening region has characteristics intermediate between the troposphere and stratosphere, and is termed the tropical transition layer (TTL). Using the ERA5 reanalysis data and trajectory analysis provided by Hysplit4, a comparative analysis was conducted on the primary pathways of air particles and the dominant weather systems in two distinct cases of equatorward and poleward cyclonic Rossby wave-breaking (CWB) events. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. It extends from the top of the troposphere to a height of about 31 miles. It extends from about 50 to 85 km (31 to 53 miles) above our planet. The seasonal changes of tropopause heights account for a flux of about 10 percent of the. Stratosphere–troposphere exchange (STE) is a part of the general circulation of the atmosphere that transports air and atmospheric constituents across the tropopause (Mohanakumar, 2008). Composition: The troposphere, stratosphere, and mesosphere are all part of the Earth’s atmosphere, which is primarily composed of nitrogen ( about 78%) and oxygen ( about 21% ). The atmosphere is divided into five layers. The AGCM is a dry hydrostatic primitive equation model with zonally symmetric boundary conditions and analytically specified physics. The stratosphere. In direct STT plumes, O 3 of stratospheric origin may change the oxidizing. The region of the. The stratosphere is stratified (layered) in temperature, with warmer layers higher and cooler layers closer to the Earth; this increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV. Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of the Earth, Venus, Jupiter, Saturn, Uranus, and Neptune. ) 2. Important greenhouse gases such as water vapor and ozone, with steep gradients between their tropospheric and stratospheric mixing ratio values, exhibit large spatial and temporal variability in the UTLS resulting from stratosphere-troposphere exchange []. A review of the papers dealing with various aspects of stratosphere-troposphere exchange (STE) is presented. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Temperature in the lower stratosphere is isothermal but. Just like the troposphere, its depth varies with latitude. 9, 2022, telescopes in space picked up a jet of high energy photons careening through the cosmos toward Earth, evidence of a supernova exploding 1. On the other hand, the troposphere has high concentrations of water vapor, is low in ozone, and. In our atmosphere, slightly over 30 miles (50 km) above the surface, where the pressure is a tenth of a percent of what it is at sea level. Stratosphere. Stratosphere-troposphere exchange (STE) of ozone represents a significant source term in the tropospheric ozone budget and can impact surface ozone concentrations, tropospheric oxidation capacity, and methane lifetime. BUY TICKETS More Info. A new study conducted by Chinese researchers directly revealed the phenomenon through in-situ. – There are no clouds in the layer, and though. Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in. The air temperature at the tropopause is about minus 80 0C over the equator and about minus 45oC over the poles. Simple, clear and accessible. The lower levels of the troposphere are usually strongly influenced by Earth’s surface. Shop 24/7 to build a better guitar! Top Rated Seller The STRATosphere is one of eBay's most. The stratosphere layer is called the ozonic atmospheric envelope because it contains most of the ozone gas (O 3) which is found in the atmospheric envelope. From the top of the troposphere to about 50 kilometres (31 miles) above the ground, the. The upper stratosphere bears the distinction of being the most stable region of significant mass in the Earth's atmosphere. Troposphere, lowest region of the atmosphere, bounded by the Earth beneath and the stratosphere above, with its upper boundary being the tropopause, about 10–18 km (6–11 miles) above the Earth’s surface. The integration of national research into international programs will allow Russia to overcome. Temperature is very much affected by the sun here; it can be 360 degrees Fahrenheit. Atmosphere - Stratosphere, Mesosphere, Ozone: The stratosphere is located above the troposphere and extends up to about 50 km (30 miles). It plays a crucial role in keeping the planet habitable by absorbing potentially dangerous ultraviolet (UV-B) radiation from the sun. STRATOSPHERE–TROPOSPHERE EXCHANGE | Global Aspects. Introduction.

However, the troposphere is especially significant, as highlighted below:Stratosphere: 14 to 64 km (9 to about 31 miles) Unlike the troposphere, temperatures in this layer increase with elevation. The solar constant is measured at. The original field developed out of observations by Woodman and Guillen (1974) of radar echoes observed from tropospheric heights using a 50 MHz ionospheric radar in Peru. The nacreous cloud (mother-of-pearl) also occurs in the stratosphere. Holton • Peter H. Take a ride to the top of the Tower, at 1,149-foot tall, it is the tallest freestanding observation tower in the United States, where you will get a chance at all the heart-pounding, adrenaline-pumping thrill rides Vegas has to offer. Stohl et al. The stratosphere is the layer that contains the ozone layer and where many important interactions take place. The gradual change from the troposphere to the stratosphere begins at approximately 7 miles (11km) high. College Park, Maryland 20740. Thermosphere . The NCEP GDAS and CPC temperature and height analyses are used to monitor processes in the Stratosphere and Troposphere. It is also the second-tallest observation tower in the Western Hemisphere, surpassed only by the CN Tower in Toronto, Ontario. However, the troposphere is especially significant, as highlighted below: Abstract The authors perform an observational study of the relation between stratospheric final warmings (SFWs) and the boreal extratropical circulation. 2015); the stratospheric concentrations of radiatively active gases such as ozone and water. Chapter. The stratosphere absorbs short wave (UV) radiation from the sun but is not hot enough to radiate much at short wavelengths. (2) Stratosphere- This layer extends from the height of about 10 to 50 km above the ground surface. Stratosphere-troposphere exchange. Overall, in the midlatitudes, they have a westerly component in the winter and an easterly component in the summer. ER-2. Climate Prediction Center. SFW events are found to provide a strong organizing influence upon the large-scale circulation of the stratosphere and troposphere during the period of spring onset. [2] [3] The stratosphere is an atmospheric layer composed of stratified temperature layers, with the warm layers of air high in the sky and the cool layers of air in the low sky. (v) the troposphere at 8–15 km. In both cases, colder regions and seasons lead to a thinner. stratosphere. • synthesize current view of stratosphere-troposphere coupling (review like) • show case new metrics (new research) • will depend in part on participation - potential for a very broad assessment, given the current level of interest • as lead authors, Yulia and I will coordinate analysis do our best to put them in a coherent storylineThe stratosphere stretches between 15 and 50 kilometers up from the Earth's surface. 0 scenario. Abstract. 10 hPa Zonal Wind. The troposphere contains about 75% of the gases in the atmosphere, and the stratosphere, which has a larger volume, contains about 19% of atmospheric gases. The meaning of STRATOSPHERE is the part of the earth's atmosphere which extends from the top of the troposphere to about 30 miles (50 kilometers) above the surface and in which temperature increases gradually to about 32°F (0°C) and clouds rarely form. Two distinct dynamical processes near the dynamical tropopause (2-PVU surface) and their relation are discussed in this study: stratosphere–troposphere exchange (STE) and the formation of. That’s the opposite of how the. From the Earth's surface to the top of the stratosphere (50km) is just under 1% of Earth's radius. A kilometer is one thousand meters. Although variations in altitude exist,. Dramatic clouds and orange sunlight all over the planet. The troposphere is characterized by decreasing temperature with height and is distinguished. When the Hunga Tonga-Hunga Ha'apai volcano erupted on January 15, 2022 in the South Pacific, it produced a shock wave felt around the world and triggered. troposphere: [noun] the lowest densest part of the earth's atmosphere in which most weather changes occur and temperature generally decreases rapidly with altitude and which extends from the earth's surface to the bottom of the stratosphere at about 7 miles (11 kilometers) high. This study estimates the stratosphere–troposphere exchange (STE) of air masses and ozone concentrations averaged over 2007 to 2010 using the Modern Era Retrospective-Analyses for Research and Applications 2 (MERRA2) and ERA5 reanalyses, and observations. Stratosphere and troposphere are the two adjoining regions of different characteristics which are coupled radiatively, chemically, and dynamically. Holger Vömel, Bruce Ingleby, in Field Measurements for Passive Environmental Remote Sensing, 2023. For example: ozone produced in the stratosphere can, when transported into the troposphere, have an important effect on tropospheric chemistry and air quality (e. Scientists sound the alarm as the world briefly smashes through 2-degree warming limit for the first time. The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. Mcintyre 2 Anne R. Quality has always been our top priority.

La stratosphère a une épaisseur d'environ 30 kilomètres et. Page Author: Climate Prediction Center Internet Team. The main reason airplanes fly in the stratosphere is because this is where the least amount of turbulence is found. Life would not have been sustainable on earth without the ozone layer located in the stratosphere. In the past, studies of stratosphere-tropo- sphere exchange of mass and chemical species have mainly emphasized the synoptic- and small-scale mechanisms of exchange. e. An increase in O 3, will produce more OḢ, which decreases lifetime of many trace gases, such as methane (CH. As nouns the difference between troposphere and stratosphere is that troposphere is the lower levels of the atmosphere extending from the earth's surface up to the tropopause. It is the second layer of the atmosphere as you go upward. Studies in recent years have found convincing evidence that the monsoon has significant impact on stratosphere troposphere exchange (STE) [e. 5. Ozone layer depletion increases the amount of UVB that reaches the Earth’s surface. 30hPa Temperature over the North Pole. It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Abstract Changes in the stratospheric polar vortex (SPV) can remarkably impact tropospheric circulation. Abstract Using monthly mean data, daily data, and theoretical arguments, relationships between surface pressure variations associated with the North Atlantic Oscillation (NAO), tropopause height, and the strength of the stratospheric vortex are established. “Meso” means middle, and this is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass. low pressure), ultraviolet-drenched environment, which is why it serves as an apt analog to life on other worlds with similar conditions. 2015); the stratospheric concentrations of. Based on the diagnosis of reanalysis data, this study finds that the location shift rather than the strength change dominates the intraseasonal variability of SPV. Stratospheric aerosol injection is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This results in the formation of very few clouds in this layer. This is often the region of the jet streams. stratosphere (n. In the upper stratosphere at least, the lifetime of Ox is sufficiently short that chemical steady state can be assumed to hold. the upper stratosphere to several years in the lower stratosphere, reflecting the abundance of O atoms (Figure 10-4, problem 10. A high concentration of ozone, a molecule composed of three atoms of oxygen, makes up the ozone layer of the . This region of the atmosphere is called the stratosphere. 1 The Density and Temperature of Air. stratosphere is known as the tropopause. Stratosphere–troposphere exchange (STE) is important for the chemical composition of both the stratosphere and troposphere. The stratosphere has less turbulence as a result. , 1995 and Haynes, 2005 for reviews). Large-scale circulation in the troposphere is primarily driven by the differential absorption of. “Thermo” means heat, and the temperature in this layer can reach up to 4,500 degrees Fahrenheit. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. For this reason, there is not a lot of turbulence in the stratosphere. Solomon, R. C) Most ozone is located in the stratosphere D) The stratosphere is stratified with the densest, coldest air at the bottom. Thanksgiving NFL games winners and losers: 49ers and Cowboys impress, Lions not so much. There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top. An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. The layer above the mesosphere is called the thermosphere. Because this layer is much closer to the sun, it can reach temperatures up to 2,000 °C (3,600 °F)Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. The stratosphere is the second major layer of Earth’s atmosphere, just above the troposphere, and below the mesosphere. G. Downward coupling of variability in the polar stratosphere drives low frequency variations in tropospheric circulation and temperature and thus can serve as a source of extended range predictability of surface weather and climate (e. The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. Chemistry of the lower and middle atmosphere plays a critical role in stratosphere-troposphere coupling processes by controlling the abundances and distribution of natural and anthropogenic agents, such as greenhouse gases, aerosols, and clouds, which regulate the incoming and outgoing radiation, temperature, and tropospheric weather events. Once in the stratosphere, it remains suspended there for many years because there is so little. Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation. The thermosphere rises several hundred miles above the Earth's surface, from 56 miles (90 km) up to between 311 and 621 miles (500–1,000 km). This layer extends from about 50 to 85 km above our planet’s earth. The ozone layer, which absorbs and scatters. The stratosphere is found above the tropopause and extends up to a height of 50 km. , Monks et al. The stratosphere has long been a challenging environment for aviation. (Stratosphere-troposphere exchange: A review and what we. The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth's polar regions. Climate - Stratospheric, Mesospheric, Winds: The winds in the stratosphere and mesosphere are usually estimated from temperature data collected by satellites. In it, tropospheric structure at the lower boundary is prescribed from the recordThe essential role of stratosphere-troposphere coupling for deep Arctic warming induced by sea-ice loss is confirmed by model simulations with stratospheric variability suppressed, in which only. , 2002). Earth Science. The ozone layer is an absorbing agent that protects life on Earth. These gases form the 5 layers of the atmosphere from top to bottom. . Further analysis suggests that it couples well with the tropospheric circulation, forming an. 6 Fahrenheit for every 1,000 feet an airplane climbs – up to about 36,000 feet. Scientists believe there may be an association between the ozone concentration and the nacreous cloud. 4) into (10. 73 - . Stratosphere. , Zachariasse et. The thermosphere is a layer of Earth's atmosphere that is directly above the mesosphere and below the exosphere. 2. Approximately 90 percent of the atmosphere’s ozone occurs in the stratosphere, the region extending from 10–18 km (6–11 miles) to approximately 50 km. 7. Stratospheretroposphere Exchange. The mesosphere is the coldest region of Earth’s atmosphere, close to -100°C. The atmosphere of the Earth is in five layers: (i) the exosphere at 600+ km; (ii) the thermosphere at 600 km; (iii) the mesosphere at 95–120 km; (iv) the stratosphere at 50–60 km; and. The stratosphere is a layer of the atmosphere that surrounds the Earth. Ozone productionmainly takes place in the tropical stratosphere as the direct solar radiation photodissociates oxygenmolecules (O 2) into oxygen atoms (O), which quickly react with other O 2 molecules to form ozone (O 3). Apr 28, 2023. The stratosphere is home to the all-important ozone layer, which filters harmful UV radiation from the sun. Solar energy is converted to kinetic energy when ozone. Here, we systematically analyze the importance of interactive chemistry with respect to the representation of stratosphere–troposphere coupling and in particular the effects on NH surface climate during the recent past. Temperature decreases with height. Sometimes ash and gas from a large volcanic eruption may burst into the stratosphere. The thermosphere lies between the exosphere and the mesosphere. These advances are now allowing for new and improved. The stratosphere is extremely dry. Between about 85 km and 600 km lies the thermosphere. At a workshop in Whistler, British Columbia (1), scien-tists met to discuss how the stratosphere re-sponds to forcing from below, initiating feedback processes that in turn alter weath-The stratosphere is the second major strata of air in the atmosphere. 59 likes. Tg of sulfur dioxide into the stratosphere. The latter includes Microwave Limb Sounder (MLS) for ozone, MLS. The mesosphere is 22 miles (35 kilometers) thick. These are used to improve our understanding of the climate system. Attractions. The stratosphere and troposphere present significantly different chemical environments, and the amount of mass and constituents transported between. Trans-port from the overworld to the troposphere is slow because the air must cross isentropic surfaces, which requires dia-Abstract and Figures.
