摘要
A zonal domain,primitive equation model is used in this paper to study the influences of the main sea surface tem-perature anomaly(SSTA)areas over the Pacific on precipitation in 1991.Some numerical experiments are made and themechanisms of the influences are discussed.The results show that the influences of the SSTA are mainly confined withinthe tropical and the subtropical regions.The direct effect of the SSTA is to change the exchanges of the sensible heat andthe water vapour between the air and the sea,through the consequent changes of temperature and the flow fields and thefeedback process of condensation,the SSTA finally affects precipitation.
