北极涛动对ENSO影响的研究进展
Progress in the Study of the Inlfuence of Arctic Oscillation on ENSO
摘要
Abstract
Arctic Oscillation (AO) is the dominant mode in the atmospheric circulation variability over the extra-tropical Northern Hemisphere. El Niño-Southern Oscillation (ENSO) is the primary mode in air-sea interaction over the tropical Pacific on interannual timescale. Variations of AO and ENSO exert substantial inlfuences on the weather and climate anomalies over large areas in the globe. This paper reviews the studies of the inlfuence of AO on ENSO, to improve our understanding the physical processes in the inlfuence of extratropical atmospheric circulation on the tropical climate. It was found that the AO in spring has a signiifcant inlfuence on the ENSO events in subsequent winter. Interaction between synoptic scale eddy and low frequency mean lfow over North Paciifc plays a key role in the formation of the spring AO-related westerly wind anomalies over tropical western Paciifc. The connection between the spring AO and subsequent winter ENSO experiences a signiifcant interdecadal change around the early 1970s. This interdecadal change is closely related to the interdecadal change in the storm track intensity over North Paciifc. The inlfuence of the spring AO on the subsequent winter is asymmetric. Spring AO can exert signiifcant inlfuences on the following winter ENSO events only in its positive phase. Spring AO has a signiifcant modulation effect on the linkage between previous winter North Paciifc Oscillation and the following winter ENSO. In addition, the AO in November can exert signiifcant inlfuences on the sea surface temperature anomalies over tropical central-eastern Paciifc in the following spring and summer. The intensiifcation of the North Paciifc storm track activity plays an important role in determining whether the variability of AO can exert inlfuences on the subsequent SST anomalies in the tropical central-eastern Paciifc.关键词
