Atmospheric circulation pattern, I The equatorial zone
Between 30° N or S & the equator, air at surface moves from subtropical highs to equatorial lows
Consistent winds toward the equator create a zone of intertropical convergence
Moving air masses experience the Coriolis effect, creating the northeasterly winds in the northern hemisphere & the southeasterly winds in the southern hemisphere
We call these winds the NE & SE trade winds
This large-scale pattern of circulating air is the Hadley cell
