Summary for the World

NOAA El Niño Advisory: There is an approximately 95% chance that El Niño will continue through Northern Hemisphere winter 2015-16, gradually weakening through spring 2016.

During November, sea surface temperature (SST) anomalies were well above average across the central and eastern Pacific Ocean. The Niño indices generally increased, although the far western Niño-4 index was nearly unchanged. Also, relative to last month, the strength of the positive subsurface temperature anomalies decreased slightly in the central and eastern Pacific, but the largest departures remained above 6oC. The atmosphere was well coupled with the ocean, with significant low-level westerly wind anomalies and upper-level easterly wind anomalies persisting from the western to the east-central tropical Pacific. Also, the traditional and equatorial Southern Oscillation Index (SOI) values became more negative (stronger), consistent with enhanced convection over the central and eastern equatorial Pacific and suppressed convection over Indonesia. Collectively, these atmospheric and oceanic anomalies reflect a strong El Niño.

All models surveyed predict El Niño to continue into the Northern Hemisphere spring 2016, and all multi-model averages predict a peak in late fall/early winter. The forecaster consensus unanimously favors a strong El Niño, with peak 3-month SST departures in the Niño 3.4 region near or exceeding +2.0oC. Overall, there is an approximately 95% chance that El Niño will continue through Northern Hemisphere winter 2015-16, gradually weakening through spring 2016.

November Wind

Most landmasses will experience average wind conditions for the month. Winds will be less than average in much of the central and western Pacific Ocean and North Indian Ocean into SE Asia and across much of Africa and southern South America. Around New Zealand will be stronger than normal as will the western and north Pacific and Atlantic Oceans and eastern Europe.

November Solar Radiation

Much of the northern hemisphere including Europe and the USA, Canada and Europe should be near normal. Western Australia and Central Africa and southern South America and New Zealand should be slightly to moderately below normal. Indonesia and the Philippines and eastern Brazil and southwest Africa should be above normal.

November Temperature Extreme Forecast Index

Cool outbreaks are limited to New Zealand, Papua New Guinea and the southernmost part of South America and eastern Russia. Meanwhile in the Pacific Ocean where the north Pacific through to the equatorial Pacific will be much warmer than normal as will be the eastern Pacific off of South America and the North Atlantic into Europe. While much of North Atlantic will be below normal the Atlantic along the USA eastern seaboard and to the east of the Caribbean will be warmer than normal. Southeast Asia will be warmer than normal. Africa with experience usual low temperatures in the south and usual high temperatures in the north.

November Precipitation Extreme Forecast Index

Northern Brazil and the western part of the North Pacific Ocean and most of the Philippines and Indonesia should be unusually to very unusually low. Central America and Mexico, southern Argentina and Chile and Western Australia and eastern China and central and East Africa and Central Asia including Iran and Afghanistan should experience unusually high extreme rainfall at some point in the month.

November Sea Surface Temperature Anomaly

The evolution of ENSO can be viewed through sea surface temperature anomaly maps. The Eastern Pacific is warmer than normal as is the Indian Ocean. The eastern central Atlantic is also warmer than normal. The ocean surrounding New Zealand is cooler than normal.

November Global Precipitation Anomaly

The Southwest of the USA including California and Northwest of Mexico and across the Midwest and Gulf States of the USA and the Caribbean show positive rainfall anomalies as does much of Central Africa and the Maldives and Sri Lanka. Central Africa and Southern Brazil also show positive precipitation anomalies. From Fiji to Vanuatu northwest through Papua New Guinea and the Indonesian archipelago, the Philippines and north and east South America and the southern coast of Chile there is a considerable negative rainfall anomaly.

November Global Temperature Anomaly

Meri Much of Canada down to the Gulf of Mexico are above normal for temperature while the western States of the USA and Maritime provinces of Canada are cooler to considerably cooler than normal. Central America and the Caribbean and the northern half of South America are above normal as is the Eastern half of Asia and most of Australia and Southeast Asia and India and southern part of the Middle East. Central Asia is much colder than normal along with much of east Africa and the norther part of the Middle East. Eastern Indonesia through Papua New Guinea and the South Pacific should be slightly cooler than normal along with New Zealand and Argentic and southern Brazil.
