Hadley Cell

The Hadley cell, named after George Hadley, is a tropical atmospheric circulation that is defined by the average over longitude, which features rising motion near the equator, poleward flow 10–15 kilometers above the surface, descending motion in the subtropics, and equatorward flow near the surface. This circulation is intimately related to the trade winds, tropical rainbelts & hurricanes, subtropical deserts and the jet streams.

There are three primary circulation cells. They are known as the Hadley cell, Ferrel cell, and Polar cell.

There is some evidence that the expansion of the Hadley cells is related to climate change ... are located in the areas underneath the descending branches of the Hadley circulation around 30 degrees latitude ... Both idealised and more realistic climate model experiments show that the Hadley cell expands with increased global mean temperature (perhaps by 2 degrees latitude over the 21st century ) this can lead to ...

    Why inspire in us a horror of our being?... To look upon the universe as a prison cell and all men as criminals about to be executed is the idea of a fanatic.
