Ocean temperatures in the equatorial Pacific are showing signs that an old acquaintance is about to pay a new visit. He will rearrange the meteorological furniture across the planet and probably outstay his welcome.
Ocean temperatures in the equatorial Pacific are showing signs that an old acquaintance is about to pay a new visit. He will rearrange the meteorological furniture across the planet and probably outstay his welcome. According to the Climate Prediction Center, it looks like El Niño is coming back.
Sea surface temperatures have warmed across the Pacific's midsection during the Spring, and more importantly, a large pulse of subsurface warmth has propagated from west to east. Click on the image of this surface warmth -- the key El Niño region is to the right of the International Dateline at 180 degrees longitude -- and watch the heat below the surface move across the ocean this spring from the western Pacific off southern Asia to the eastern Pacific off South America.

"These surface and subsurface oceanic anomalies typically precede the development of El Niño," the climate center observed in its monthly discussion of conditions in the region.
