It changes sometimes unpredictably The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. Stratosphere is the second layer. The stratosphere is one of five layers of the atmosphere. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In comparison, the warmest in the thermosphere. It has different layers with different qualities. The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. The stratosphere is a layer of Earths atmosphere. 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). Ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). During northern hemispheric winters, sudden stratospheric warmings, caused by the absorption of Rossby waves in the stratosphere, can be observed in approximately half of winters when easterly winds develop in the stratosphere. Thats the opposite of how the layers work in the troposphere, where we live. Why Is Carbon Important? 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 ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. Facts About Stratosphere - GKToday Three Highest Thrill Rides in the World. Earth's Atmospheric Layers | NASA A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Stratosphere - Definition, Functions & Characteristics with Videos - BYJUS On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. 3. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). Polar stratospheric clouds (PSCs) are the exception. We humans live in the troposphere, and nearly all weather occurs in this lowest layer. 27. 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. The layer made of layers. 3090 Center Green Drive, Boulder, CO 80301, Virtual Ballooning to Explore the Atmosphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. 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). The stratosphere is a layer of Earths atmosphere. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). This part of the atmosphere is the most dense. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. measured by the humidity of the air. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. [5] Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter). Air density is the lowest, and its temperature can increase up to 1500 degrees Celsius. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. It has increased the number of respiratory conditions such as asthma. 34. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. Its upper edge has maximum ozone concentration, referred to as the ozone belt. Strat means layer. Convection is the process whereby warm air rises and cooler air descends. Stratospheric circulation is a predominantly wave-driven circulation in that the tropical upwelling is induced by the wave force by the westward propagating Rossby waves, in a phenomenon called Rossby-wave pumping. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. 17. They result from ionized particles from the sun striking the upper atmosphere above the poles. Just like the troposphere, its depth varies with latitude. It is the second layer of the atmosphere as you go upward. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. This layer of our atmosphere has its own set of layers. 11. 77 Exciting Facts about the Atmosphere - LovePsychologys What Is the Greenhouse Effect? The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. 28. The air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. This layer is 22 miles (35 kilometers) thick. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. Aurora is also referred to as polar light. The stratosphere is the second layer of the atmosphere. 10. There are some species of birds capable of flying in the stratosphere. Endeavoring to achieve professional growth through ongoing development of skills and using new and accepted methods of . Temperature increases with height until the estimated top of the thermosphere at 500 km. [22][23], In 1902, Lon Teisserenc de Bort from France and Richard Assmann from Germany, in separate but coordinated publications and following years of observations, published the discovery of an isothermal layer at around 1114km, which is the base of the lower stratosphere. Ozone layer facts and information - Environment Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth. This is how certain gases become trapped in the stratosphere, like CFC's and ozone. 6. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere It extends from about 50 to 85 km (31 to 53 miles) above our planet. Mercury's magnetic field is different at its poles. On top of that, air samples from this altitude have shown that certain types of bacteria and microbes are present in the stratosphere, making it the closest to space and furthest from the Earth's surface that humans have found life naturally living. 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. The lack of particles in the air causes less friction to hold an aircraft back, which requires less power to travel faster and further. Also known as Nacreous Clouds, these unique clouds develop near the poles at an altitude of 15 - 25 kilometers (9 - 15 miles) during the winter months. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. Stratospheric warming of the polar vortex results in its weakening. Stratosphere - Wikipedia Fun Stratosphere Facts for Kids. The temperatures at the different atmospheric layers differ depending on solar radiation, humidity, and altitude. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. Thats almost as wide as Earth itself. Although humans would not be able to survive in the stratosphere due to thin air and frigid temperatures, there is life that can and does survive there. A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. Mercury has water ice and organics. . 14. This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. 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. The Stratosphere | Center for Science Education It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. The mesosphere is directly above the stratosphere and below the thermosphere. The ionosphere is not a distinct layer like the others mentioned above. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion. Sunlight is reflected in every direction by the gases present in the atmosphere. 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 stratosphere is where youll find the very important ozone layer. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. The Brief Overview. 40 Unbelievable But True Troposphere Facts | Kidadl This diagram shows some of the features of the stratosphere. The next higher layer above the stratosphere is the mesosphere. Since the stratosphere has increasing temperature with elevation, convection is very rare. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) The rising air is literally freeze dried; the stratosphere is a very dry place. We now know that there are additional ozone loss mechanisms and that these mechanisms are catalytic meaning that a small amount of the catalyst can destroy a great number of ozone molecules. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. Earths atmosphere is similar to a jacket for our planet. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. 16. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . 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. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. Earth is a great planet to live on because it has a wonderful atmosphere around it. Create your account. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. 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. Interesting Facts About Mercury. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). The latter value is about halfway to the Moon! Near the equator, the lower edge of the stratosphere is as high as 20km (66,000ft; 12mi), at midlatitudes around 10km (33,000ft; 6.2mi), and at the poles about 7km (23,000ft; 4.3mi). The stratosphere is where youll find the very important ozone layer. Ozone, which is actually a molecule made up of three oxygen atoms linked together by covalent bonds, absorbs harmful ultraviolet radiation that enters the Earth's atmosphere as part of sunlight. 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. Moreover, it regulates the temperature extremes that are likely to occur between day and night. ], While looking up at the sky on a cloud-free day, one will see what looks like a continuous piece of[], The stratosphere is the second layer of the atmosphere, It extends from a height of approximately 10 km. 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).
