SEASONAL VARIATION IN EFFECT OF SEA-SURFACE TEMPERATURE IN THE EQUATORIAL EASTERN PACIFIC ON CHARACTERISTIC INDEX OF SUBTROPICAL HIGH AT 500 mb

The Long-term Weather Forecasting Group in the Institute of Geography, Academia Sinica, analysed the impacts of the Eastern Equatorial Pacific (5°N —10°S, 80°W—180) SST (sea-surface temperature) on the long-term trends in the characteristic indices of the subtropical high at 500mb, and found that the existence of
