Using correlation analysis, the relationships of the number of the heavy precipitation over lower reaches of the Yangtze river valley (LYRV) in summer to the global zonal wind at 50 hPa during previous winter are explored. And the climate prediction model with the KLM filter technique is developed. The results show that there are three regions with significant correlation between the number of the heavy precipitation over LYRV and the global zonal wind at 50 hPa during previous winter, which occur near the North Pole, over the middle latitude of North Pacific, in the high latitude of the Southern Hemisphere. Based on the stratospheric winds of these key regions, the prediction model the number of the heavy precipitation over LYRV in summer can be better predicted for last 10 years, which the prediction for KLM filter technique is significantly better than multiple linear regression prediction. In these connections, correlations to the stratospheric zonal winds of the North Pole and he high latitude of the Southern Hemisphere are stable, and to that over the middle latitude of North Pacific, to some extent, is instable. So, the prediction from KLM filter technique can offfer important to operational prediction of the short term climate prediction for heavy precipitation over LYRV.
