Understanding climate models
If you’ve heard about any climate cycle, it’s probably the El Niño Southern Oscillation, or ENSO. 2015/2016 is looking like it might bring a record El Niño, and media coverage is, for climate, pretty remarkable.
The coverage is understandable, as weird things happen during big El Niños. The eastern tropical Pacific Ocean is anomalously warm during boreal winter. Deep convection moves away from the Western Pacific Warm Pool, and other bits of the climate system tend to shift to unusual states.
