The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . Geomagnetic solar storms caused by solar flares or solar winds can disrupt activities in the ionosphere, causing difficulty in transmitting radio signals and global positioning system signals. 90% of the ozone layer is found in the stratosphere's upper crust. However, the distance of 100 kms from the earths surface is what is considered generally as an imaginary boundary. Convection is the process whereby warm air rises and cooler air descends. The stratosphere is a layer of Earths atmosphere. [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, close . This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. They go from the ground all the way to outer space. Although it is situated above the upper reaches of conventional aircraft, scientists are still able to study it through the use of weather balloons, high-altitude aircraft, and also weather (sounding) rockets. Create an account to start this course today. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. [6], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. They are much similar to warm breath during cold weather. 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 (about 30 miles) above Earth's surface. Planes and jets will sometimes. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. Since the stratosphere has increasing temperature with elevation, convection is very rare. The photosynthesis process enables plants to take up carbon dioxide and release oxygen into the atmosphere. Create your account. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. 22. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. These are generated when cold atmospheric air blends with the hot, humid exhaust. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. It borders the mesosphere above through a thin transitional space called the stratopause. There are forms of biological bacteria living in the stratosphere. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. All other trademarks and copyrights are the property of their respective owners. The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world. A two-step reactive mechanism produces ozone in the stratosphere naturally. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. The ozone layer is situated within this layer. The stratosphere is located above the troposphere and below the mesosphere. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. That's almost as wide as Earth itself. As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. 21.

This ozone layer is important for man's survival, and for the survival of life on earth, as it absorbs the UV radiation from the sun that would otherwise be deadly. So, what does the stratosphere do? These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. Providing an environment conducive to good instruction and motivation in which there is an atmosphere of self-motivation and self-discipline in the areas of personal development, character, and academic integrity. Like an onion, the Earth's atmosphere is composed of many layers. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). Moreover, it regulates the temperature extremes that are likely to occur between day and night. #1. The stratosphere is very cold, ranging in temperatures from negative 68F to negative 5F. Within the stratosphere temperatures increase with altitude (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (3C or 26.6F).[8]. An interesting feature of stratospheric circulation is the quasi-biennial oscillation (QBO) in the tropical latitudes, which is driven by gravity waves that are convectively generated in the troposphere. Ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). It is easy & understandable to view our atmosphere as a continuous layer of air. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. The layer of very rare air above the mesosphere is called the thermosphere. In the lower atmosphere (the troposphere) near the Earth's surface, ozone is created by chemical reactions between air pollutants . 4. They are found at altitudes of 15 to 25 km (9.3 to 15.5 miles) and form only when temperatures at those heights dip below -78 C. They appear to help cause the formation of the infamous holes in the ozone layer by "encouraging" certain chemical reactions that destroy ozone. At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space.

PSCs appear in the lower stratosphere near the poles in winter. Sydney Chapman gave a correct description of the source of stratospheric ozone and its ability to generate heat within the stratosphere;[citation needed] he also wrote that ozone may be destroyed by reacting with atomic oxygen, making two molecules of molecular oxygen. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude. As it absorbs the UV light, it absorbs energy. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. The destruction of the ozone layer lets an enormous amount of ultraviolet rays reach the earth, which leads to skin cancer and cataracts in humans and animals alike. This diagram shows some of the features of the stratosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. As a result of the EUs General Data Protection Regulation (GDPR). This is the opposite of what happens in the troposphere, where an increasing altitude yields a decrease in temperature. The more humid the atmosphere is, the thicker the contrails will be. 3090 Center Green Drive, Boulder, CO 80301, Air pressure drops, and temperatures get colder, as you climb higher in the troposphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. That means that to get to outer space, you have to be really far from Earth. The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. Of all the atmospheric layers, this is the most closest to the Earth. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. Biosphere forms part of the troposphere where life exists. Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. [12] Eustace also broke the world records for vertical speed skydiving, reached with a peak velocity of 1,321km/h (822mph) and total freefall distance of 123,414ft (37,617m) lasting four minutes and 27 seconds.[13]. The atmosphere gradually changes as the climate and weather change. Earth is a great planet to live on because it has a wonderful atmosphere around it. 7. The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The mesosphere is directly above the stratosphere and below the thermosphere. This layer of our atmosphere has its own set of layers. Since the ozone layer absorbs UV rays from the sun, it heats up, which allows temperatures to increase as altitude increases. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. 8. Most airplanes or jets travel in the lower part of the stratosphere. Its like a teacher waved a magic wand and did the work for me. There are little to no clouds in the stratosphere from the lack of convection. Within no time, the vapor from the exhaust freezes and turns visible. The overall circulation of the stratosphere is termed as Brewer-Dobson circulation, which is a single-celled circulation, spanning from the tropics up to the poles, consisting of the tropical upwelling of air from the tropical troposphere and the extra-tropical downwelling of air. [20], Some bird species have been reported to fly at the upper levels of the troposphere. 12. The stratosphere is one of five layers of the earth's atmosphere. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. All Rights Reserved. The ozone layer is very important, as it protects life on Earth from the majority of the UV rays emitted from the sun. 25. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. The Concorde aircraft cruised at Mach 2 at about 60,000ft (18km), and the SR-71 cruised at Mach 3 at 85,000ft (26km), all within the stratosphere. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. Sunlight is reflected in every direction by the gases present in the atmosphere. While common in the troposphere, very little convection takes place in the stratosphere. The stratosphere is located above the troposphere and below the mesosphere. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere. Without it, the earths surface would be so cold that living here would not be possible. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. If you were to climb a mountain in the stratosphere you would have to take off your warm clothes as you got closer to the top rather than putting them on like we usually do. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. 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. Discover fun facts about the stratosphere and stratosphere characteristics. Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun. A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_3',116,'0','0'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_4',116,'0','1'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_1');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_5',116,'0','2'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_2');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_6',116,'0','3'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_3'); .large-billboard-2-multi-116{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:3px !important;margin-left:auto !important;margin-right:auto !important;margin-top:3px !important;max-width:100% !important;min-height:250px;min-width:300px;padding:0;text-align:center !important;}Recent Posts, Copyright 2023 by Own Your Weather. On October 24, 2014, Alan Eustace became the record holder for reaching the altitude record for a manned balloon at 135,890ft (41,419m). As harmful UV rays from the sun become absorbed in the ozone layer, this layer heats up. 19. 14. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. Ozone is a gas made up of three oxygen atoms (O 3). They have been observed by airline pilots and the international space station. In 1985, they observed a hole in the ozone layer above the Antarctic. The Earth's atmosphere is made up of roughly 78% nitrogen, 21% oxygen, 0.9% argon, and 0.1% other gases. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. Air pollution causes the demolition of the ozone belt, and without it, the earth would be exposed to the deadly ultraviolet rays in the sun. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. The troposphere, the lowest layer, is right below the stratosphere. She has taught in K-12 for more than 15 years, and higher education for ten years. Most of the clouds form in the troposphere, just below the stratosphere. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. This material is based upon work supported by the National Center for Atmospheric Research, a major facility sponsored by the National Science Foundation and managed by the University Corporation for Atmospheric Research. Almost all weather is in this region. The chlorine atoms are recycled when ClO reacts with O in the upper stratosphere, or when ClO reacts with itself in the chemistry of the Antarctic ozone hole. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. Its upper edge has maximum ozone concentration, referred to as the ozone belt. Like the other atmospheric layers, it does not have a fixed height but starts at an altitude of approximately 10 km(6 miles), extending up to a height of roughly 50 km(30 miles). UCAR/Randy Russell The stratosphere is the second layer in the Earth's atmosphere. Write CSS OR LESS and hit save. I feel like its a lifeline. The layer made of layers. As you might imagine, the "air" in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. There are some species of birds capable of flying in the stratosphere. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. Its about 6,200 miles (10,000 kilometers) thick. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. . Mesosphere lies between 50-85 km above sea level. 31. Meteors burn up in the coldest layer, the mesosphere. 12 chapters | (The lack of weather activity in the stratosphere also allows aircraft to avoid adverse weather conditions by flying in the lower stratosphere above the weather.). While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. The ionosphere is not a distinct layer like the others mentioned above. It changes sometimes unpredictably Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. 30. Mercury's magnetic field is different at its poles. The stratosphere extends from the tropopause at about 10 to 17 km (about 6 to 11 miles) altitude to its upper boundary (the stratopause) at . The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. It borders the troposphere below through a thin transitional space called the tropopause. Why Is Carbon Important? The lower boundary of the stratosphere can be as high as 20 km (12 miles or 65,000 feet) near the equator and as low as 7 km (4 miles or 23,000 feet) at the poles in winter. 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. 23. Without the stratosphere, life on Earth would be very different or non-existent, as the shielding of the sun's radiation is important for known Earth life. Air circulation within the stratosphere is dominated by the Brewer-Dobson Circulation, which is a single-celled air movement that stretches from the Poles to the Equator. It is enough to cover the entire earths surface with 1 cm of rain. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. 2 It extends from a height of approximately 65 km (40 miles) to 85 km (53 miles) above the Earth's surface. The exosphere is the very edge of our atmosphere. Autumn Skies Online Pty Ltd also participates in affiliate programs with Clickbank, CJ, ShareASale, and other sites. 3 It borders the stratosphere below through a thin transitional space called the stratopause. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet. This site is owned and operated by Autumn Skies Online Pty Ltd, a limited liability company headquartered in Somerset West, South Africa. "Strat" means layer. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. Terms & Conditions It contains the ozone layer and is between the troposphere, the first layer of the atmosphere, and the mesosphere, the third layer of the atmosphere. 26. It has increased the number of respiratory conditions such as asthma. Most meteors burn up in the mesosphere. The next higher layer above the stratosphere is the mesosphere. In many ways, the thermosphere is more like outer space than a part of the atmosphere. Instead, the ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules. The stratosphere is home to the ozone layer, which is a thin layer of concentrated ozone which plays an essential role in protecting the Earth from dangerous solar radiation. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. [24], Seinfeld, J. H., and S. N.(2006), Atmospheric Chemistry and Physics: From Air Pollution to Climate Change 2nd ed, Wiley, New Jersey. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. It is the only layer of the atmosphere where temperature inversion occurs. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. Acidic rains destroy plants and animals, and if it reaches rivers and lakes, it destroys all the aquatic life. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere Although on average the stratosphere begins at about 7 miles up from the earth's surface, it can range from 5 miles at the earth's poles, to 6-8 miles at moderate latitudes, to 11 miles at the equator. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. As altitude increases, air density in the layers of the atmosphere decrease. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. Instead, clouds condense in the troposphere. The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name and endowing this region with some special properties. This layer is 22 miles (35 kilometers) thick. In comparison, the warmest in the thermosphere. These "blue jets" appear above thunderstorms, and extend from the bottom of the stratosphere up to altitudes of 40 or 50 km (25 to 31 miles). The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. [4] The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. We take a closer look at the stratosphere and its defining characteristics. These distances vary slightly due to elevation changes on the Earth. It is the reason why the sky appears blue. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). The exosphere gradually fades away into the realm of interplanetary space. Nitrous oxide (N2O) is produced by biological activity at the surface and is oxidised to NO in the stratosphere; the so-called NOx radical cycles also deplete stratospheric ozone. The exosphere is really, really big. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. Thus it means layer which surrounds the earth. Due to this, the stratosphere has very little convection, which causes chemicals derived from aerosols, known as CFC's, to become confined to the stratosphere. The coldest temperatures are found in the mesopause. All rights reserved. "Strat" means layer. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. The layer made of layers Above the troposphere and below the mesosphere, we have the stratosphere. No tracking or performance measurement cookies were served with this page. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. 33. Mercury has water ice and organics. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. As a result, it tends to trap any and all gases that enter this region of the atmosphere. 18. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. This article focus on the stratosphere, Earth's second layer. This layer separates the rest of the atmosphere from outer space. You might have seen planes leaving white condensation trails. Atmosphere Atmosphere and Its Layers Planes and jets will sometimes choose to fly in the stratosphere, where there are no clouds or weather that can affect the ride. The stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The site owner may have set restrictions that prevent you from accessing the site. The stratosphere is a region of intense interactions among radiative, dynamical, and chemical processes, in which the horizontal mixing of gaseous components proceeds much more rapidly than does vertical mixing. (Learn more about Nacreous or Polar Stratospheric Clouds in this article.). The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. Damage to the ozone layer of the stratosphere occurs naturally when volcanic gases and dust reach the stratosphere, but people have been contributing to this as well with the use of aerosol's containing CFCs.
