Abstract:
Distributions of monthly sea surface temperature(SST) anomaly field over the equatorial Pacific and the northern Pacific have short-term climatic oscillations in the past 40 years. Analysis shows that the tropospheric geopotential heights over the Northern Hemisphere have certain effects upon the general circulation and during the first phase period of SST climatic oscillation (before mid-1970s) ,the mean height of troposphere has a falling tendency. However,during the latter phase period, it has a rising tendency. The results suggest that this kind of correlation at the upper level is better than that at the lower level, it is more stable over the low latitudes than that over the mid- and high latitudes and distinctive in the summer than that in winter.
