What happens to temperature with an increase in altitude in the tropopause?

In the tropopause, the temperature remains relatively constant. This atmospheric layer serves as the boundary between the troposphere, where weather events and temperature decreases with altitude, and the stratosphere, where temperature begins to increase with altitude.

Throughout the troposphere, temperature typically decreases as one ascends, due to the thinning of the atmosphere and the decreasing air pressure. However, once you reach the tropopause, which is the upper limit of the troposphere, the temperature stabilizes and no longer sees that typical decline. This stable temperature profile is crucial for various atmospheric processes and helps maintain the separation of weather phenomena (which occur in the troposphere) from the stratospheric conditions above.

Understanding this constant temperature is essential for meteorology and atmospheric science, as it influences weather patterns, the behavior of jet streams, and the distribution of various atmospheric phenomena. This characteristic of the tropopause sets it apart from the layers of the atmosphere both below and above it.
