计算发现赤道东太平洋和北太平洋流区海温与山东夏季降水相关性好，在此基础上，讨论了山东夏季旱涝年同期、前期ＳＳＴ异常的特征及其与大气环流的相互关系，发现同期ＳＳＴ异常显著，前期赤道东太平洋ＳＳＴ负异常与５００ｈＰａ大气环流负ＷＰ遥相关型关系密切，北太平洋流区海温异常很可能受环流异常的调制。利用２—４月高相关区ＳＳＴＡ做当年夏季降水趋势预测的试验和利用赤道东太平洋区３月、北太平洋流区７月海温做长期夏季降水预测的试验表明，ＳＳＴ可以对山东夏季的旱涝预测提供非常有价值的参考。
The correlation between SST in the equatorial East Pacific and North Pacific and summer precipitation in Shandong is found. Based on the above, the characteristics of SST anomalies in summer and the antecedent period of summer are discussed. The anomalous SST is significant. The anomalous SST in the former equatorial Pacific is closely related to the WP negative correlation at 500hPa, and the anomalous SST anomalies in the North Pacific are likely to be modulated by the anomalous circulation. Tests and Utilization of Current Summer Precipitation Trend Forecast from February to April High Correlated Area SSTA for the Current Year In the eastern equatorial Pacific region, a trial of long-term summer precipitation forecast for the July SST in the North Pacific Ocean region in March shows that SST can predict the summer drought in Shandong Waterlogging prediction provides a very valuable reference.
