equinoctial rains

Rainy seasons that occur regularly in many places within a few degrees of the equator at or shortly after the equinoxes.

This characteristic of two distinct annual precipitation maxima is found chiefly within a tropical rain forest climate. The main regions are the Congo Valley, the greater Amazon Valley, and the East Indies. In most places, the spring maximum is the greater.
Compare zenithal rains.
