What's in the Atmosphere? It is made up of 78% nitrogen and 21% oxygen. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. The temperature increases to about negative {eq}5 {/eq} F in the stratosphere. Terms & Conditions The stratosphere is a very interesting layer in Earth's atmosphere, as there are many fun stratosphere facts outside of its primary characteristics that make it unique. [6] Winds in the stratosphere can far exceed those in the troposphere, reaching near 60m/s (220km/h; 130mph) in the Southern polar vortex. Various types of waves and tides in the atmosphere influence the stratosphere. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. From space, the earth is seen as a blue halo. It is like a giant magnet and retains high-energy particles, thereby protecting the earth. We take a closer look at the stratosphere and its defining characteristics. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. The stratosphere is composed primarily of nitrogen and oxygen. Scientists have been warning people for many years about the damage we are doing to the ozone layer. The stratosphere accounts for approximately 24% of the earth's total atmosphere. Aurora is also referred to as polar light. Earth's atmosphere is similar to a jacket for our planet. 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. At the outer limit of the magnetic field is the magnetosphere. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. PSCs appear in the lower stratosphere near the poles in winter. 29. 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. Layers of the atmosphere: troposphere, stratosphere, mesosphere . Moreover, it regulates the temperature extremes that are likely to occur between day and night. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. 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). The layer made of layers Above the troposphere and below the mesosphere, we have the stratosphere. The stratosphere is a layer of Earths atmosphere. Earths atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. . They are a combination of supercooled water and nitric acid that develop at very low temperatures. The atmosphere has nearly 37.5 million billion gallons of water at any given time. Skin cancer frequency is increasing due to the thinning of the ozone layer. 4. That's much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. Thislayerseparates the rest of the atmosphere from outer space. 3. 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. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. 27.

The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. 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. The burning of fossil fuels discharges carbon dioxide, while agricultural developments deposit a lot of methane and nitrogen oxides into the atmosphere. Luckily the situation has improved since the ban of chlorofluorocarbon. They are much similar to warm breath during cold weather. PSCs are also called nacreous clouds. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. We are not permitting internet traffic to Byjus website from countries within European Union at this time. I would definitely recommend Study.com to my colleagues. Just like the troposphere, its depth varies with latitude. Life as we know it wouldnt be possible without this layer of protection. Its about 6,200 miles (10,000 kilometers) thick. "Strat" means layer. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Moreover, the distance between the molecules increases as you move up the different layers. Above the troposphere and below the mesosphere, we have the stratosphere. Without the stratosphere, life on Earth would be much different, if not non-existent. This is how certain gases become trapped in the stratosphere, like CFC's and ozone. The jet stream flows near the border between the troposphere and the stratosphere. It has increased the number of respiratory conditions such as asthma. All Rights Reserved. - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. It means temperatures rise as altitude increases in this region, unlike the other four layers, which are characterized by a drop in temperature as altitude increases. Another large-scale feature that significantly influences stratospheric circulation is the breaking planetary waves[15] resulting in intense quasi-horizontal mixing in the midlatitudes. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. I feel like its a lifeline. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. But its not the same everywhere. They go from the ground all the way to outer space. For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. The troposphere is the lowest layer of our atmosphere. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. 3 It borders the stratosphere below through a thin transitional space called the stratopause. 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. These distances vary slightly due to elevation changes on the Earth. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. The Earth's atmosphere is a mixture of several gases. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV . 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. She has taught in K-12 for more than 15 years, and higher education for ten years. In the lower atmosphere (the troposphere) near the Earth's surface, ozone is created by chemical reactions between air pollutants . Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. [4] The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. Never miss out again when another interesting and helpful article is released and stay updated, while also receiving helpful tips & information by simplyclicking on this link .Until next time, keep your eye on the weather! The stratosphere is a layer of Earths atmosphere. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. 21. A single chlorine atom can destroy more than a hundred thousand ozone molecules. N.Butchart, A.A. Scaife, J. Austin, S.H.E. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. The coldest temperatures in Earths atmosphere, about -90 C (-130 F), are found near the top of this layer. 28. 23. It is the reason why the sky appears blue. 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. Privacy Policy The mesosphere is a layer of Earth's atmosphere. The latter value is about halfway to the Moon! The coldest temperatures in Earth's atmosphere, about -90 C (-130 F), are found near the top of this layer. So, what does the stratosphere do? 34. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. 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. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. The Earth's atmosphere is very important, as each layer plays a role for life on Earth. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. The composition of the atmosphere of each celestial body is different. 17. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere. The more humid the atmosphere is, the thicker the contrails will be. Ionization takes place in the ionosphere caused by the suns radiation. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. At the top of the stratosphere, the density of the air is close to zero. Mercury has water ice and organics. 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. The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. Brewer-Dobson Circulation occurs in the stratosphere. It is the only layer of the atmosphere where temperature inversion occurs. 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. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. 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. #1.

We live in the troposphere, which is the layer of the atmosphere closest to earth. We live in one layer, called the troposphere, where the clouds and most of the water vapor reside. Mercury's magnetic field is different at its poles. 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 atmosphere is dense near the surface of the Earth and protects life on the planet Earth.
