What occurs in the tropopause?

The tropopause is the boundary layer between the troposphere and the stratosphere, typically characterized by a temperature inversion where temperatures stabilize or increase with altitude. It plays a crucial role in weather patterns, as it acts as a cap that limits vertical mixing of air, thus influencing cloud formation and storm development. Additionally, the tropopause can vary in altitude depending on geographic location and weather conditions, being higher in the tropics and lower at the poles.
