WebIn the tropics and subtropics, the tropopause is high, often reaching to about 18 km (11 miles), as a result of vigorous vertical mixing of the lower atmosphere by thunderstorms. In polar regions, where such deep atmospheric turbulence is much less frequent, the tropopause is often as low as 8 km (5 miles). WebThe stratosphere is the layer of Earth's atmosphere immediately above the troposphere; it extends from a lower boundary (the tropopause) whose altitude varies between about 8 and 16 km to an upper boundary (the stratopause) near 50 km.

WebIn the tropics, the tropopause is found at higher altitude (16–17 km), while in the polar regions it can be as low as 7–8 km. After World War II, rocket temperature soundings began to be made up to altitudes of about 100 km and global mean vertical temperature profiles or “standard atmospheres” were produced. Web10 apr. 2024 · A filament of dry, high-PV air was extruded from the overlying tropopause fold within an intensifying front-transverse circulation in this region. This dry filament eventually penetrated to low levels immediately behind the front, where it undercut the upper, rearward parts of the wide cold-frontal precipitation band.

The tropopause is defined as the lowest level at which the lapse rate decreases to 2°C/km or less, provided that the average lapse-rate, between that level and all other higher levels within 2.0 km does not exceed 2°C/km.
