From “NASA Observatory“:
In the winter of 2013-14, an unusually strong and persistent ridge of atmospheric high pressure emerged in weather maps of the northeastern Pacific Ocean. The feature, which was so unrelenting that meteorologists took to calling it the Ridiculously Resilient Ridge, weakened winds in the area enough that the normal wind-driven churning of the sea eased. Those winds usually promote upwelling, which brings deep, cool water up toward the surface; instead, the resilient ridge shut down the ocean circulation, leaving a large lens of unusually warm surface water in the northeastern Pacific.
At times, this patch of warm water seeped into the Bering Sea, the Gulf of Alaska, and the coastal waters off Washington, Oregon, and California. In fact, many parts of the northeastern Pacific experienced the greatest sea surface temperature anomalies in the historical record. Scientists and journalists took to calling the patch of warm water “the Blob.” Nicholas Bond, a University of Washington meteorologist and the Washington state’s climatologist, coined the term in a June 2014 newsletter.
As unusually warm surface water sloshed around for months, the grim consequences began to ricochet through the marine food Article source: http://www.actionnewsjax.com/weather/buresh-blog-big-area-of-northeast-pacific-warm-water-is-finally-cooling-off/94814751
