Sea surface temperature temperature pattern is when warm water spreads from the west Pacific and the Indian Ocean to the east Pacific. It takes the rain with it, causing extensive drought in the western Pacific and rainfall in the normally dry eastern Pacific. El Niño's warm rush of nutrient-poor tropical water, heated by its eastward passage in the Equatorial Current, replaces the cold, nutrient-rich surface water of the Humboldt Current. When El Niño conditions last for many months, extensive ocean warming and the reduction in Easterly Trade winds limits upwelling of cold nutrient-rich deep water and its economic impact to local fishing for
The Blob (Pacific Ocean) second off Alaska and in the Bering Sea; and the third and smallest, off Southern California and Mexico. In February 2014, the temperature of the Blob was around warmer than what was usual for the time of year. A NOAA scientist noted in September 2014, based on ocean temperature records, that the North Pacific Ocean had not previously experienced temperatures so warm since climatologists began taking recordings. The immediate cause of the phenomenon is the lower than normal rates of heat loss from the sea to the atmosphere, compounded with lower than usual water circulation resulting in a static upper
