Abstract

Abstract

The air-sea coupled features are investigated associated with Eastern Pacific (EP) La Niña and Central Pacific (CP) La Niña during seasonal evolution, by using the monthly sea surface temperature from HadISST, subsurface sea temperature from SODA, and reanalysis data from NCEP/NCAR. For EP La Niña, the sea surface temperature anomalies (SSTA) occur over South American coast in developing summer and then are displaced westward. The negative SSTA center covers the eastern equatorial Pacific during the mature phase. Nevertheless, no significant propagation of SSTA is observed for the CP La Niña and its SSTA center maintains at around 160°W. The CP La Niña-SSTA are more intensive and persist longer compared to the EP La Niña. Tropical atmosphere responses are different for two types of La Niña. The CP La Niña is featured by a stronger intensity, a larger extent, and a slightly westward displacement in moist divergence compared to the EP La Niña. As a response to the two types of La Niña, height anomalies are both weak in developing summer and autumn. A negative Pacific-North America (PNA) pattern tends to be dominant during La Niña winters. However, their intensity and location differ from each other. Almost opposing North Atlantic Oscillation (NAO)-like atmospheric anomalies occur during the EP and CP La Niña winters, which may cause very different regional climate anomalies.
