tropopaussi

Tropopaussi is a term used to describe the boundary between the troposphere and the stratosphere. It is not a sharply defined line but rather a transition zone where the temperature profile of the atmosphere changes significantly. In the troposphere, the layer closest to the Earth's surface, temperature generally decreases with altitude. This is because the troposphere is heated from below by the Earth's surface absorbing solar radiation. As altitude increases, the distance from this heat source grows, leading to cooler temperatures.

The tropopause marks the point where this temperature decrease stops and is replaced by a region where temperature remains relatively constant or even increases with altitude. This region of constant or increasing temperature is characteristic of the stratosphere. The tropopause is therefore a crucial layer that influences atmospheric circulation and weather patterns. Its altitude varies depending on latitude and season, being higher at the equator and lower at the poles, and generally higher in the summer than in the winter. The tropopause plays a role in the vertical transport of moisture and pollutants between the troposphere and the stratosphere, impacting climate and air quality.
