Pacific Ocean one branch flows around Cape Horn and the other turns north to form the Peru or Humboldt Current. The climate patterns of the Northern and Southern Hemispheres generally mirror each other. The trade winds in the southern and eastern Pacific are remarkably steady while conditions in the North Pacific are far more varied with, for example, cold winter temperatures on the east coast of Russia contrasting with the milder weather off British Columbia during the winter months due to the preferred flow of ocean currents. In the tropical and subtropical Pacific, the El Niño Southern Oscillation (ENSO) affects weather conditions.
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
