Abstract

Abstract

In terms of intensive observed precipitation data and hydrological information of the Huaihe River Basins (referred as HRB Hereinafter), the spatial-temporal distribution of precipitation and climatic features during the summer of 2003 are analyzed. Comparison is made with the year of 1954 and 1991 for the same period. Results show that 7 weather processes occurred with the total precipitation, river-level and flow are more than those of 1991, but less than 1954. Also, flood peak reduced with time. Main rainfall features in the target regions in 2003 are stable rain-belt, intensive and explosive storm-rainfall. More precipitation during spring of 2003, southward-shifted subtropical high in July 2003, antislope in the middle HRB are important causes for the whole HRB over danger water-level.
