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.
3 maj 2022 · 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.
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.
30 lis 2023 · The stratosphere is the second-lowest level in Earth's atmosphere. It's a bastion of ozone gas and rapid winds, where clouds are scarce — but life endures. Sometimes referred to as "near space," it's where companies and countries are in a race to send new technology that can collect data and intelligence, snap high-resolution images, and even ...
11 kwi 2022 · Within the troposphere, temperature decreases rapidly with increasing elevation to values near 50 °C below freezing at its upper boundary, where the stratosphere begins. Most of the stratosphere, which extends to about 50 kilometers above the surface, is cold and free of clouds.
22 sty 2013 · The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. Stratosphere. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.
10 gru 2020 · Coupling between the stratosphere and the troposphere contributes to extreme events at the Earth’s surface, and can help with predictability on timescales from weeks to decades, according to a ...
