Tropopause Seasonal Changes MET

As well as the generic heights of the tropopause (Equator 16km; Mid-latitudes 11km; Poles 8km) you are also required to know how the height changes with the seasons. This is relatively straightforward: during summer for that hemisphere the air warms and expands, resulting in a thicker troposphere and a higher tropopause.

The exception is around the equator: because it is warm all year round, there is no real change in temperature and so the tropopause height remains relatively constant.
