El Nino's mass of warm water puts a lid on the normal currents of cold, deep water that typically rise to the surface along the equator and off the coast of Chile and Peru, said Stephanie Uz, ocean scientist at Goddard Space Flight Center in Greenbelt, Maryland.
When that warm water reaches the western Pacific it rises and, in the main, tracks back along the equator in the upper atmosphere and loses its heat to space.
The primary effect of the two tropical Hadley cells (one for each hemisphere) is for the rising hot air at the equator to suck surface air from the higher latitudes (north and south) along the surface towards the equator, pump it vertically at the equator, and at a suitable height push it polewards, one pole per cell, up where the jet planes fly.
The descended air then travels toward the equator along the surface, replacing the air that rose from the equatorial zone, closing the loop of the Hadley cell.
