What is the Blob 2021?
A multi-year ocean heat wave known as “the Blob” may have temporarily disrupted the biological pump that cycles carbon dioxide deep into the Pacific Ocean for up to thousands of years at a time, a new study has found.
Where is the Blob now?
The Blob Appears It hung out in the Gulf of Alaska during 2015-2016 (when we experienced the largest Common Murre die-off on record); now there are three patches—one in the Bering Sea; one off the California/Mexico coast; and one off the coast of Canada, Washington, and Oregon.
When was the last El Niño in Los Angeles?
2018-2019
El Niño events in 1982-1983 and 1997-1998 drenched the West Coast with record rain. The last El Nino, a weak one, occurred in 2018-2019. El Niño means the little boy or Christ child in Spanish.
What are the effects of El Niño in Los Angeles?
During a La Niña year, winter temperatures are warmer than normal in the South and cooler than normal in the North. La Niña can also lead to a more severe hurricane season. La Niña causes the jet stream to move northward and to weaken over the eastern Pacific.
Where is the Southern blob?
Published 27 August 2021. They’re calling it ‘The Blob’—a pool of unusually warm water off the east coast of New Zealand, which is believed to be responsible for a 10-year megadrought in parts of South America.
What is the southern blob?
(CNN) In the southwest Pacific Ocean, there’s a huge region of unusually warm water covering an area about the size of Australia, known as “the Southern Blob.”
Is the Blob gone?
A NOAA scientist noted in September 2014 that, based on ocean temperature records, the North Pacific Ocean had not previously experienced temperatures so warm since climatologists began taking measurements. In 2015 the atmospheric ridge causing the Blob finally disappeared. The Blob vanished shortly after in 2016.
What is the heat blob in the Pacific Ocean doing to climate?
The heat wave may cause a source of food to die off or migrate. Heat waves can also lead to toxic algae blooms that can kill fish. The events can affect humans, too. The blob in the Pacific may have influenced weather patterns on the West Coast, worsening drought in California, for example.
Are we in La Niña or El Niño?
Based on all the available data, an official La Nina watch is still in effect, released by the NOAA’s Climate Prediction Center: “La Niña is likely to continue into the Northern Hemisphere spring (77% chance during March-May 2022) and then transition to ENSO-neutral (56% chance during May-July 2022).
What does La Niña mean California 2021?
Scientists predict that La Niña this winter will lead to below average precipitation in a large swath of California, stretching from the Bay Area to the state’s southern border. They expect warmer than average temperatures for Southern California and eastern parts of Central California.
What caused the Blob?
Marine heat waves like The Blob are caused by combinations of several factors, such as high air temperatures, changing wind patterns, and regular ocean warming events like the El Niño Southern Oscillation in the Pacific Ocean.
Where is the warmest water in the Pacific?
The warmest ocean water of the year in California lies off Newport Beach and Santa Catalina Island in August when temperatures average 70 degrees F (21 °C).
When was the warm blob?
By summer of 2014, the heated mass of water stretched from Alaska to Mexico and had been nicknamed “the blob.” As the blob spread, unusually warm waters triggered extended harmful algae blooms….References.

Where is the cold blob?
the North Atlantic
The cold blob in the North Atlantic (also called the North Atlantic warming hole) describes a cold temperature anomaly of ocean surface waters, affecting the Atlantic Meridional Overturning Circulation (AMOC) which is part of the thermohaline circulation, possibly related to global warming-induced melting of the …
Is the Pacific blob back?
The atmospheric ridge dissipated in 2015, and the blob finally subsided in early 2016, but marine animals—and the many coastal industries that depend on them—will take much longer to return to normal. Some species may take years to recover.
What causes marine heatwaves?
Marine heatwaves are caused by a variety of factors, including shorter term weather phenomena such as fronts, intraseasonal, annual, or decadal modes like El Niño events, and longer term changes like climate change.
What is the overall temperature trend between 1880 and 2010?
Describe the average temperature change from 1880 to 2010. The average temperature increased about 0.8°C between 1880 and 2012.
Will it be a wet winter in California 2021?
November 2021 to October 2022. Winter will be warmer and drier than normal, with below-normal mountain snows. The coldest temperatures will occur from mid-December into mid-January, in mid-February, and in early March. The stormiest period will be in late December.
