长江中下游6月份降水的一个预报指标

THE PREDICTION INDEX FOR THE PRECIPITATION IN THE MIDDLE AND LOWER REACHES OF CHANGJIANG RIVER IN JUNE

根据１９６３～１９９２年嵊山海洋站２月海气感热输送和２２ａ太阳磁周期与 降水的关系，提出了一个长江中下游 ６月降水的综合预报指标。用此指标，对１９９３ 年６月长江中下游降水进行回报，结果与实况一致。

Based on the relations of the air-sea sensible heat flux around Chengshan station in East China Sea in February and the 22 year magnetic period of the solar spots with the precipitation in the middle and lower reaches of Changjiang River in June, a prediction index was proposed. The prediction for the precipitation for above region in June 1993 is well consistent with the actual rainfall.
