Reappraisal of the Influence of ENSO Events on Seasonal Precipitation and Temperature in China
ENSO事件对我国季节降水和温度的影响

This paper describes the composite analyses of seasonal precipitation and temperature in China during ENSO events in last 40 years and test of confiedence leveL It is shown that both the rainfall and temperature are lower than normal on the whole in the ENSO year and almost opposite anomalies occur in the following year in most part of China. The seasonal rainfall and temperature departures evolve with almost opposite phases. The seasonal rainfall anomalies in the middle and lower reaches of the Yangtze River with certain level of statistical confidence occur in spring and autumn of the ENSO year and in spring of the following year, rather than in springs of both year. The most significant cooling in Northeast China also appears in autumn of the ENSO year through spring of the following year, rather than in the summers. Finally, some results on ENSO influence previously obtained are reappraised based on the present analyses.
