[Early Online Release] Effect of decadal changes in air–sea interaction on the climate mean state over the tropical Pacific
Date：2014-08-05
Recent studies highlight the impact of a La Ni？a-like mean state change on the predominance of central Pacific (CP) El Ni？o in the most recent decade. On the other hand, using a linear shallow-water model, it is found that the air-sea interactions in 1980–98 and 1999–2011 tend to generate CP and eastern Pacific (EP) El Ni？o, respectively. And changes of air-sea interactions from 1980–98 to 1999–2011 prompt the generation of the La Ni？a-like pattern, which is similar to the background change in the most recent decade.
