Overall, the attenuation of solar UV at wavelengths that damage DNA by the ozone layer allows life to exist on the surface of the planet outside of the ocean. All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere.
20 sie 2024 · The stratosphere extends from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). This layer holds 19 percent of the atmosphere's gases but very little water vapor. In this region, the temperature increases with height.
10 gru 2020 · The stratosphere, the layer of the atmosphere at heights between 10-50 km, is an important source of variability for the weather and climate at the Earth’s surface on timescales of weeks to...
2 wrz 2024 · About 30 kilometers above the continent’s icy surface, in the layer known as the stratosphere, a series of warming events took place starting in July 2024. July temperatures in the stratosphere above Antarctica are typically around minus 80 degrees Celsius (minus 112 degrees Fahrenheit).
19 paź 2024 · stratosphere, layer of Earth’s atmosphere lying between the troposphere and the mesosphere. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude.
11 kwi 2022 · The atmosphere has a surface pressure of 1 bar and is composed primarily of \(N_2\) and \(O_2\), plus such important trace gases as \(H_2O\), \(CO_2\), and \(O_3\). Its structure consists of the troposphere, stratosphere, mesosphere, and ionosphere.
31 sty 2022 · At the equator, the stratosphere begins at about 17 km altitude above the Earth's surface (sea level) At the poles, the layer starts at about 10 kilometers in height. Above this layer, there is the troposphere. On the other side, over it, the mesosphere begins at an altitude of 50 km from the Earth's surface.
