Hold onto your surfboards, El Niño is experiencing a late-fall resurgence. A recent weakening of tradewinds in the western and central equatorial Pacific triggered a strong eastward wave of warm water known as a Kelvin wave. It’s headed to South America.

You can see the wave in the red-and-white line marking an area of sealevel in the central and eastern equatorial Pacific standing 4 to 7 inches higher than normal. That’s the result of heat expansion where sea surface temperatures have risen 2 to 4 degrees Fahrenheit above normal.

In contrast, the western equatorial Pacific is experiencing lower than normal temperatures, with sealevels 3 to 6 inches below normal. You can see that in the blue and purple areas.

The image was created with data collected by a US/French Space Agency satellite (the Ocean Surface Topography Mission/Jason-2 oceanography satellite) during 10 days this month.

Forecast: Everything gets wilder.
 

Fact:

In-depth journalism that investigates the powerful takes real money and is so damn important right now.But it doesn’t take a Mother Jones investigation to know that billionaires and corporations will never fund the type of reporting (like they do politicians) we do that exists to help bring about change. Instead, our mission-driven journalism is made possible by people power, and has been for 46 years now since our founding as a non-profit.

In “TITLE TK” Monica Bauerlein writes about the perilous moment we’re in, and why it’s so important that we raise $325,000 by the time November’s midterms are decided so we can be ready to throw everything we have at the big issues facing the nation no matter what happens.
