On the Average the Tropopause Is Highest over the?

The tropopause is lowest over the poles (approximately 26 000 ft or 8 km) and highest over the equator (approximately 52 000 ft or 16 km).

Where is the tropopause the highest?

The highest average tropopause is over the oceanic warm pool of the western equatorial Pacific, about 17.5 km high, and over Southeast Asia, during the summer monsoon, the tropopause occasionally peaks above 18 km.

Why is the tropopause higher over the equator?

The troposphere is thicker over the equator than the poles because the equator is warmer. Heat differential on the planet's surface causes convection currents to flow from the equator to the poles. ... Thus the simple reason is thermal expansion of the atmosphere at the equator and thermal contraction near the poles.
