equatorial easterlies

(Also called deep trades, deep easterlies.) As used by some authors, the trade winds in the summer hemisphere when they are very deep, extending to at least 8–10 km altitude, and generally not topped by upper westerlies.

If upper westerlies are present, they are too weak and shallow to influence the weather. In the winter hemisphere, these easterlies are restricted to a narrow belt along the equator.
Compare tropical easterlies.
