A possible response of the atmospheric Hadley circulation to equatorial anomalies of ocean temperature

Bjerknes, J.
  • Finds that the occurrence in late 1957 and early 1958 of above-normal surface water temperatures in the tropical Pacific from the American coast westward to the dateline provided a large anomalous heat source for the atmosphere that intensified its thermodynamic circulation, especially in the wintertime (northern) hemisphere
  • Finds that the anomalous heat source for the atmosphere resulted in record intensity of the westerlies in the eastern North Pacific
  • Finds the anomalous depth of the Low in the Gulf of Alaska had the downwind effect of weakening the Iceland Low and setting the stage for a cold winter in northern Europe
