All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. The rising air is literally freeze dried; the stratosphere is a very dry place. The top of the stratosphere is called the stratopause, above which the temperature decreases with height.
The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat.
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.
12 gru 2020 · The stratosphere layer is called the ozonic atmospheric envelope because it contains most of the ozone gas (O 3) which is found in the atmospheric envelope. It is the second layer of the atmospheric envelope.
The stratosphere is very dry air, containing little water vapor. Because of this, few clouds are found in this layer. Polar stratospheric clouds (PSCs) are the exception. PSCs (also called nacreous clouds) appear in the lower stratosphere near the poles in winter.
3 maj 2022 · Stratosphere. The stratosphere is the layer bounded by the tropopause at its base (12 km; 7.5 mi; 39,000 ft)) up to the stratopause (55 km; 31 to 34 mi; 164,000 to 180,000 ft). Air pressure within the stratosphere is only about 1/1000 of the pressure at sea level.
25 cze 2024 · Earth’s atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space.
