Pause 1
Pause 1 : (Atm Phys) A thermal transition zone in the atmosphere. Note: The tropopause lies at approx 8 miles altitude, between the troposphere and the stratosphere; the stratopause at approx 15 miles altitude, between the stratosphere and the mesosphere; and the meso-pause at approx 50 miles altitude, between the mesosphere and the thermosphere. Heights vary with the seasons, distance from the poles, and other factors
