Did you know?
WebThe Hadley cell is a closed circulation loop which begins at the equator. There, moist air is warmed by the Earth's surface, decreases in density and rises. A similar air mass rising on the other side of the equator forces those rising air masses to move poleward. The rising air creates a low pressure zone near the equator. WebThe rising air creates a circulation cell, called a Hadley Cell, in which the air rises and cools at high altitudes moves outward (towards the poles) and, eventually, descends back to the …

So we create these big spinning circles of air that we call the Hadley cells near the equator where the air is rising it loses its ability to hold moisture and you get …
Webpoleward extent of the Hadley cell is set by the location where the thermally driven jet first becomes baroclinically unstable. The expansion of the Hadley cell is caused by an increase in the subtropical static stability, which pushes poleward the baroclinic instability zone and hence the outer boundary of the Hadley cell.

This Coriolis Effect causes the air that has risen at the equator and moving to the poles to deflect and become increasingly westerly high up in the atmosphere, and the circulation breaks down. As a result, the air sinks back towards the ground in the subtropics (30° – the ‘horse latitudes’). flor dorada warrior cats
