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) The Blob (Pacific Ocean) The Blob is a large mass of relatively warm water in the Pacific Ocean off the coast of North America. It was first detected in late 2013 and continued to spread throughout 2014 and 2015. Sea surface temperature indicated that The Blob persisted into 2016, but was thought to have dissipated later that year. By September 2016, "The Blob" resurfaced and made itself known to meteorologists. This warm water mass is unusual in ocean conditions and is considered to have a role in the formation of the unusual weather conditions felt in the Pacific Coast of
