Tropopause - Wikipedia
网页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.
Tropopause - an overview | ScienceDirect Topics
网页The tropopause is defined as the natural boundary between the troposphere and the stratosphere, characterized by differences in temperature, potential vorticity, and chemical composition such as ozone and water vapor. It can vary in altitude between approximately 6 km and 18 km depending on the location and weather conditions.
Continuous rise of the tropopause in the Northern Hemisphere
网页2021年11月5日 · Tropopause height (H) is a sensitive diagnostic for anthropogenic climate change. Previous studies showed increases in H over 1980–2000 but were inconsistent in projecting H trends after 2000. While H generally responds to temperature changes in the troposphere and stratosphere, the relative importance of these two …

Tropopause | atmospheric region | Britannica
网页…of the troposphere, called the tropopause, corresponds to the level in which the pattern of decreasing temperature with height ceases. It is replaced by a layer that is essentially isothermal (of equal temperature). In the tropics and subtropics, the tropopause is high, often reaching to about 18 km (11 miles),… Read More; troposphere

网页The tropopause is the boundary between the troposphere and the stratosphere. In dynamical meteorology it is typically defined as an iso-surface of potential vorticity (PV) because the tropospheric low-PV values clearly differ from the …
Troposphere | Weather, Climate Change & Air Pollution
网页Troposphere, lowest region of the atmosphere, bounded by the Earth beneath and the stratosphere above, with its upper boundary being the tropopause, about 10–18 km (6–11 miles) above the Earth’s surface. The troposphere is characterized by decreasing temperature with height and is distinguished.
