August 2013: Hottest Ocean Surface Temperatures on Record Defy ENSO, Spur Continental Deluges
(Image source: NOAA)
ENSO, the global regulator for, generally, how much heat the world ocean system dumps into the atmosphere, remained on the cool side of neutral for much of August 2013. Ocean surface temperatures in the Eastern Equatorial Pacific remained 1 to 2 degrees Celsius below the 1981-2010 average for most of the month. In a normal year, such departures would tend to depress both global ocean and land surface temperature averages. But, for the world’s global oceans and related land atmospheric system, all was well outside the range of normal.
For beyond the Eastern Equatorial Pacific, most of the world’s oceans ranged from .5 C to up to 4 C hotter than average. A particularly hot region dominated an area east of Shanghai in the Pacific bordering China, Japan and the Korean Peninsula. The hot surface water extended under the powerful influence of an anomalous heat dome…
