Since the Eastern Tropical Pacific is not entirely decoupled from West Wind Drift given the general pattern of circulation in the SE Pacific, the question arises is the magnitude of the observed overall energy difference in the recently observed «extended» La Nina phase of ENSO condition relative to the the «more normal» ENSO comparable in magnitude to energy associated with the apparent increase in winds and potentially currents around the Antarctic?
«We think the recent snowy winters could be caused by the retreating Arctic ice altering atmospheric circulation patterns by weakening westerly winds, increasing the amplitude of the jet stream and increasing the amount of moisture in the atmosphere,»

The circulation pattern described above — ascent in the equatorial trough, poleward movement in the upper troposphere, descent in the subtropical ridges, and equatorward movement in the trade winds — is in effect a direct heat engine, which meteorologists call the Hadley cell.
That would change the air circulation patterns resulting in the observed wind effect on the ocean surfaces but would itself have been caused by changes in the rate of release or absorption of energy from the ocean surfaces.
