摘　　要：根据强震成因的外核对流上升体顶托说,一个强震的震中下面是外核的一个对流上升脉冲点,从物理学的"拍频原理"可知,两个强震的中点也是一个外核脉冲点,将其称为"外核拍频(地热)涡"。仔细分析了近50年来出现在我国西北区的外核拍频涡,发现它与降水距平百分率R′>100%的强雨区相配合,这为水灾的短期气候预测提供了科学依据。According to the outer core convective fluid uprising theory of strong earthquake cause,there was an outer core convection pulse point under the strong earthquake center.Based on ＇the beat principle＇ in physics,it is found that there was also an outer core pulse point located in two strong earthquake centers,called ＇the outer core beat（geothermal） vortex＇.The outer core beat vortex occurred in Northwest China in recent 50 years were analyzed.The results showed that the outer core beat vortex always accords with the severe rainfall area with the precipitation anomaly percent100%,which provide a science basis for the short-term climate prediction of flood.
