The tropopause is a thermodynamic gradient-stratification layer, that marks the end of the troposphere, and is approximately 17 kilometres (11 mi) above the equatorial regions, and approximately 9 kilometres (5.6 mi) above the polar regions . Meer weergeven The tropopause is the atmospheric boundary that demarcates the troposphere from the stratosphere, which are the lowest two of the five layers of the atmosphere of Earth. The tropopause is a thermodynamic gradient … Meer weergeven Rising from the planetary surface of the Earth, the tropopause is the atmospheric level where the air ceases to become cool with increased altitude and becomes dry, devoid of water vapor.

Reidel Publishing Company Meer weergeven The troposphere is the lowest layer of the Earth's atmosphere; it starts at the planetary boundary layer, and is the layer in which most weather phenomena occur. The troposphere contains the boundary layer, and ranges in height from an average of 9 … Meer weergeven The tropopause is not a fixed boundary. Vigorous thunderstorms, for example, particularly those of tropical origin, will overshoot into the lower stratosphere and undergo a brief (hour-order or less) low-frequency vertical oscillation. Such oscillation … Meer weergeven • The height of the tropopause Meer weergeven Web31 jan. 2024 · 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.
