Influence of the Pacific sea surface temperature anomalies on the circulation and its numerical experiments
|
Abstract:
The general circulations over the Pacific during the episodes of El Nino(1982-83, 1986-87) were analyzed with the wind data taken from Monthly Climatic Data for the World. And they were also simulated with a nine-layer primitive equation model.The results of analysis and experiments show that both periods of SST anomalies in the tropical Pacific make the circulation change apparently. However, the influences of these episodes on the Walker circulation and Hadley circulation are somewhat different because the strength, extent and the time that the SST anomalies lasted are not the same. The characteristic of the Walker circulation and Hadley circulation during the two episodes of El Nino in the eighties and the results of our simulations will be presented briefly in this paper.
