The convection pattern between 30°S and 30°N latitude is best described by the following response: Hotter air rises and moves away from the equator, then cools and falls and moves back to the equator.
This pattern can be attributed to the Hadley Cell phenomenon, where warm air rises near the equator, moves poleward at high altitudes, cools, descends around 30° latitude, and then returns equatorward at the surface.
