Geography and Environment (PCS) World climates

Despite Sun being overhead throughout the year at the equator, it receives comparatively less insolation than the tropics. This can be due to

1. Heavy cloudiness due to continuous evaporation that reduces the amount of solar insolation

2. Absence of Coriolis force at the equator

Explanation:

Statement 1: Generally, at the same latitude the insolation is more over the continent than over the oceans, because oceans are cloudier due to greater evaporation. Similarly in equator, evaporation is high, cloudiness is high and rains are frequent. Clouds reflect incoming solar insolation and send it back to space.
Statement 2: Zero coriolis force would mean that winds are not deflected with great force at the equator, as they are the sub-tropics. But, direction of wind will only affect the distribution of heat, and not the amount of insolation actually received from the Sun.
