What is the common boundary layer between the troposphere and the stratosphere called?

The common boundary layer between the troposphere and the stratosphere is referred to as the tropopause. This boundary is significant because it marks the transition between these two atmospheric layers, which have distinct characteristics.

In the troposphere, which extends from the Earth's surface up to the tropopause, temperature generally decreases with altitude. This is the layer where most of our weather occurs. As you reach the tropopause, the temperature stabilizes and begins to increase as you enter the stratosphere, which is characterized by this temperature inversion. The tropopause acts as a cap, preventing the turbulent mixing of air between the troposphere and stratosphere, and plays a crucial role in the formation of jet streams and the overall functioning of the atmosphere.

Understanding the characteristics and significance of the tropopause is essential in atmospheric science, particularly in meteorology and aviation, as it influences weather patterns and flight planning.
