The lack of particles in the air causes less friction to hold an aircraft back, which requires less power to travel faster and further. As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. Thus it means layer which surrounds the earth. In 1985, they observed a hole in the ozone layer above the Antarctic. stratosphere The atmospheric layer above the troposphere, which extends on average from about 10 to 50 km above the Earth's surface. Skin cancer frequency is increasing due to the thinning of the ozone layer. Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. They go from the ground all the way to outer space.
Earth's Atmospheric Layers | NASA The stratosphere accounts for approximately 24% of the earth's total atmosphere.
Atmosphere Layers: Facts About the Atmosphere Layers 2011 UCAR with portions adapted from Windows to the Universe ( 2009 NESTA). Also, magnetic and south poles reverse at uneven intervals of hundreds of thousands of years.
Ozone is a chemical compound consisting of three oxygen atoms. The stratosphere is a layer of extremely stratified air that rises 40 kilometres above the tropopause and comprises about 20% of the atmosphere's mass. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. All other trademarks and copyrights are the property of their respective owners. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Planes that are low on fuel also fly at this altitude because they can cover more distance than in the troposphere while using less fuel and encountering less turbulence. The stratosphere contains approximately 19% of the earth's total atmospheric gases. At the outer limit of the magnetic field is the magnetosphere. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. measured by the humidity of the air. Temperature decreases with height throughout the mesosphere. Other gases that make up the remaining 0.1 percent include trace amounts of carbon dioxide, methane, water vapour, and neon. Most turbulence at this altitude is caused by variations in the jet stream and other local wind shears, although areas of significant convective activity (thunderstorms) in the troposphere below may produce turbulence as a result of convective overshoot. . 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. Commercial airliners fly in the lower stratosphere to avoid the weather, travel faster, and save fuel. Life as we know it wouldnt be possible without this layer of protection. The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. 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. Folland. Some of these waves and tides carry energy from the troposphere upward into the stratosphere, others convey energy from the stratosphere up into the mesosphere. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. It is seen in high latitude areas as shimmering curtains of lights that are visible at night. Composition of the Earth's atmosphere. Without the stratosphere, life on Earth would be much different, if not non-existent. The exosphere is really, really big. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. CTRL + SPACE for auto-complete. It is easy & understandable to view our atmosphere as a continuous layer of air. A two-step reactive mechanism produces ozone in the stratosphere naturally.

Rainbow Facts: What Is A Rainbow And How Does It Occur? The top of the stratosphere is called the stratopause, above which the temperature decreases with height. The stratosphere protects Earth life from extremely harmful UV rays from the sun. 9. [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 to the planetary surface of the Earth. 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. Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. The water exists in the form of vapor and invisible to plain eyes. Without it, the earths surface would be so cold that living here would not be possible. Since almost almost weather activity is limited to the troposphere and almost no water vapor is present in the stratosphere, Polar Stratospheric Clouds is the only visual meteorological phenomenon that can be observed in the stratosphere. 24. All rights reserved. 12. "Strat" means layer. It's about 6,200 miles (10,000 kilometers) thick. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. The stratosphere is one of the 5 layers of the atmosphere, situated above the troposphere and below the mesosphere at an altitude of 10 km (6 miles), extending to 50 km (30 miles). Earth's atmosphere is similar to a jacket for our planet. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. Most airplanes or jets travel in the lower part of the stratosphere. Since the ozone layer absorbs UV rays from the sun, it heats up, which allows temperatures to increase as altitude increases. The next higher layer above the stratosphere is the mesosphere. Mesosphere lies between 50-85 km above sea level. This diagram shows some of the features of the stratosphere. If you do your calculations, each water vapor particle spends approximately nine days in the atmosphere. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. Ionization takes place in the ionosphere caused by the suns radiation. This layer of our atmosphere has its own set of layers. Most of the clouds form in the troposphere, just below the stratosphere. For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. The mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere.) Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. The next higher layer above the stratosphere is the mesosphere. This layer of our atmosphere has its own set of layers. Just above that is the stratosphere, the area of the atmosphere where passenger airplanes and weather balloons fly. The definition of the stratosphere is the second layer of the atmosphere, extending from about 6 miles to 30 miles, or 10km to 50km, above the Earth's surface. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. The mesosphere is directly above the stratosphere and below the thermosphere. Ozone (O3) photolysis produces O and O2. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere where we live and breathe and the vacuum of space. 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. However, the air in this layer is so thin that it would feel freezing cold to us! [11] This optimizes fuel efficiency, mostly due to the low temperatures encountered near the tropopause and low air density, reducing parasitic drag on the airframe. It extends above the tropopause to an altitude of 50 km above the earth.
Ozone depletion | Facts, Effects, & Solutions | Britannica These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. The more humid the atmosphere is, the thicker the contrails will be. Stratosphere. 90% of the ozone layer is found in the stratosphere's upper crust. Ozone is a gas made up of three oxygen atoms (O 3). All Rights Reserved. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Moreover, the distance between the molecules increases as you move up the different layers. This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. It contains most of our Earth's water vapour, and is 78% nitrogen and 21% oxygen. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. The greenhouse gases increase the effect making the earths surface to be warmer than usual. You might have seen planes leaving white condensation trails. It lies above the troposphere, the layer closest to Earth, and below the mesosphere. Create an account to start this course today. There are some species of birds capable of flying in the stratosphere. It changes sometimes unpredictably The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. The stratosphere is located above the troposphere and below the mesosphere. There are forms of biological bacteria living in the stratosphere. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. 25. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. . Brewer-Dobson Circulation occurs in the stratosphere. It is the reason why the sky appears blue. The stratosphere also has an increasing temperature with increasing altitude, which is different than what happens in the troposphere. This is how certain gases become trapped in the stratosphere, like CFC's and ozone.
