Vertical air exchange in the troposphere takes hours to days whereas mixing in the stratosphere takes months to years. read more

What makes the stratosphere and troposphere distinct layers is a temperature change. Basically the troposphere is defined by the decreasing temperature from the ground up, and the stratosphere starts at the point where the temperature starts to rise again. read more
