During an ENSO event, the prevailing trade winds weaken, reducing upwelling and altering ocean currents such that the sea surface temperatures warm, further weakening the trade winds.

An El Nino analysis released by the national weather service last week says sea surface and sub-surface temperature anomalies were consistent with El Niño during December, but the overall atmospheric circulation continued to show only limited coupling with the warm water.

If the highly suspect Sea Surface Temperature «Bucket Model» adjustments are removed, then the warming during the first half of the 20th century would be significantly larger than than the warming during the second half of the century...

''... worked with two sediment cores they extracted from the seabed of the eastern Norwegian Sea, developing a 1000 - year proxy temperature record «based on measurements of δ18O in Neogloboquadrina pachyderma, a planktonic foraminifer that calcifies at relatively shallow depths within the Atlantic waters of the eastern Norwegian Sea during late summer,» which they compared with the temporal histories of various proxies of concomitant solar activity... This work revealed, as the seven scientists describe it, that «the lowest isotope values (highest temperatures) of the last millennium are seen ~ 1100 - 1300 A.D., during the Medieval Climate Anomaly, and again after ~ 1950 A.D.» In between these two warm intervals, of course, were the colder temperatures of the Little Ice Age, when oscillatory thermal minima occurred at the times of the Dalton, Maunder, Sporer and Wolf solar minima, such that the δ18O proxy record of near - surface water temperature was found to be «robustly and near - synchronously correlated with various proxies of solar variability spanning the last millennium,» with decade - to century - scale temperature variability of 1 to 2 °C magnitude.»

Figure 8 shows where Sea Surface Temperatures warm and cool during the evolution (the negative lags) of an ENSO event, at the peak of an ENSO event (zero lag), and during the decay of ENSO events (the positive lags).

Furthermore, significant warming during the satellite sea surface temperature record (1982 — 2009) is mainly limited to the summer months... we speculate that Bering Sea primary productivity is likely to rise under conditions of future warming and sea ice loss.&raqsea surface temperature record (1982 — 2009) is mainly limited to the summer months... we speculate that Bering Sea primary productivity is likely to rise under conditions of future warming and sea ice loss.&raqSea primary productivity is likely to rise under conditions of future warming and sea ice loss.&raqsea ice loss.»

The best way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian Ocean as a mirror of the Pacific Ocean sea surface temperature anomalies [much like the Western Hemisphere Warm Pool creates such a SST mirror with the Atlantic Ocean too]: during a La Niña episode, waters in the eastern Pacific are relatively cool as strong trade winds blow the tropically Sun - warmed waters far towards the west.

Increased surface melting, loss of ice shelves, and reduction of summer and autumn sea ice around the Antarctic and Greenland continents during the warmest interglacials would have a year - round effect on temperature, because the increased area of open water has its largest impact on surface air temperature in the cool seasons.
