what are 3 facts about the stratosphere
The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. At the outer limit of the magnetic field is the magnetosphere. 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 QBO induces a secondary circulation that is important for the global stratospheric transport of tracers, such as ozone[14] or water vapor. Terms & Conditions Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. As it absorbs the UV light, it absorbs energy. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). They shoot upwards through the stratosphere in a blue column to altitudes as high as 50km! Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Strat means layer. The atmosphere gradually changes as the climate and weather change. As altitude increases, air density in the layers of the atmosphere decrease. 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. It contains most of our Earth's water vapour, and is 78% nitrogen and 21% oxygen. It is located just above the troposphere, which is the first layer of the atmosphere closest to the ground. The site owner may have set restrictions that prevent you from accessing the site. This diagram shows some of the features of the stratosphere. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). The ionosphere is not a distinct layer like the others mentioned above. 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 jet stream flows near the border between the troposphere and the stratosphere. The ozone layer, which absorbs and scatters the . Above the stratosphere is the mesosphere. This diagram shows some of the features of the stratosphere. 90% of the ozone layer is found in the stratosphere's upper crust. What Causes Air Pollution? This article focus on the stratosphere, Earth's second layer. The temperature increases to about negative {eq}5 {/eq} F in the stratosphere. 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. Its depth also varies from 5.5 to 20 miles depending on latitude as well. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. Due to the high speed of the meteor, it generates a lot of heat resulting from high friction between the particles and the meteor. Many satellites actually orbit Earth within the thermosphere! The stratosphere is a layer of Earth's atmosphere. 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. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. "Strat" means layer. All other trademarks and copyrights are the property of their respective owners. The stratosphere is located above the troposphere and below the mesosphere. What Is the Greenhouse Effect? As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. Above the troposphere and below the mesosphere, we have the stratosphere. All Rights Reserved. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. 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. You might have seen planes leaving white condensation trails. In many ways, the thermosphere is more like outer space than a part of the atmosphere. Ice clouds form in this layer which is visible when lighted from beneath during sunset. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. Most meteors burn up in the mesosphere. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The ozone layer is very important, as it protects life on Earth from the majority of the UV rays emitted from the sun. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. In this article, we are going to learn about the atmosphere. The infamous ozone layer is found within the stratosphere. The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. Skin cancer frequency is increasing due to the thinning of the ozone layer. Thislayerseparates the rest of the atmosphere from outer space. This layer holds 19 percent of the atmosphere's gases but very little water vapor. There are some species of birds capable of flying in the stratosphere. This is due to the temperature changes within the stratosphere. 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. 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. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. So, what does the stratosphere do? Thats the opposite of how the layers work in the troposphere, where we live. Stratospheric warming of the polar vortex results in its weakening. [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. On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. Above the stratosphere lies the mesosphere, thermosphere, and exosphere. A Division ofAutumn Skies Online (Pty) Ltd Disclaimer 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. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . Be grateful! It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. 110 lessons. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. Theexosphereis really, really big. Rainbow Facts: What Is A Rainbow And How Does It Occur? Privacy Policy The temperatures decrease by 6.5 degrees Celsius each kilometer, reaching -55 degrees Celsius at the top limit of the troposphere, commonly known as the tropopause. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. 6. [18] When the vortex is strong, it keeps the cold, high-pressure air masses contained in the Arctic; when the vortex weakens, air masses move equatorward, and results in rapid changes of weather in the mid latitudes. Earths atmosphere is similar to a jacket for our planet. Life as we know it wouldnt be possible without this layer of protection. . 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. PSCs are also called nacreous clouds. Interesting Facts About Mercury. The stratosphere protects Earth life from extremely harmful UV rays from the sun. The air in the mesosphere is far too thin to breathe (the air pressure at the bottom of the layer is well below 1% of the pressure at sea level and continues dropping as you go higher). The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Troposphere. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. Earth's atmosphere is a jacket of gases that surrounds our planet. Create an account to start this course today. Hare, J.R. Knight. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. We live in one layer, called the troposphere, where the clouds and most of the water vapor reside. Ionosphere plays a vital role in radio signals broadcast on the earths surface. Autumn Skies Online Pty Ltd also participates in affiliate programs with Clickbank, CJ, ShareASale, and other sites. There is very little water vapor in this layer of the atmosphere, so clouds are a rare occurrence. The water ice appears younger than we would expect. This vertical stratification, with warmer layers above and cooler layers below, makes the stratosphere dynamically stable: there is no regular convection and associated turbulence in this part of the atmosphere. 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. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is the second layer of the atmosphere. Earths atmosphere has six different layers. 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). However, the distance of 100 kms from the earths surface is what is considered generally as an imaginary boundary. [4] Temperatures range from an average of 51C (60F; 220K) near the tropopause to an average of 15C (5.0F; 260K) near the mesosphere. Planes and jets will sometimes. To learn more about each layer of the atmosphere, click the images below. While common in the troposphere, very little convection takes place in the stratosphere. The ozone layer is within the stratosphere, which protect the Earth from harmful radiation emitted by the sun. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. This layer separates the rest of the atmosphere from outer space. This is also where you'll find low Earth orbit satellites. 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 troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). We live in the troposphere, which is the layer of the atmosphere closest to earth. CTRL + SPACE for auto-complete. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. The atmosphere has nearly 37.5 million billion gallons of water at any given time. The layer made of layers. The atmosphere consists of five distinct layers, with the stratosphere being the second, situated just above the troposphere. Earth's atmosphere is similar to a jacket for our planet. Air density in this layer gradually decreases as you go higher. The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere.
