Characteristics of Sea Surface Height in Tropical Pacific and Its Relationship With ENSO Events
Using the monthly sea surface height （SSH） data of Godas between 1980 and 2008, the paper analyzed the different seasons of tropical Pacific sea surface height of seasonal and the annual variations, and preliminarily discussed the correlation between anomalies of the sea surface height and the ENSO events. The results are as follows. 1 ） To the equatorial regions, the sea surface height of East Pacific area is lowest, the Northwest Pacific and Southwest Pacific are highest, the central Pacific region is lower. 2） The interannual variability of sea surface height in Northwest Pacific and Southwest Pacific is large, and the eastern equatorial Pacific in the fall and winter is large. 3） In the tropical Pacific interannual variability of sea surface height at 1,4,10 months have a good correspondence with the ENSO events. When E1 Niflo events occur, the sea surface height of eastern tropical Pacific increased, west and southwest decreased, and the anomalous areas are slightly different in different season. The anomaly spatial form of sea surface height is not close with the ENSO events in July.
