Using the historical daily precipitation data from the 132 stations in the Haihe River Basin over the period of 1961-2012, the statistical characteristics of the rainstorms in the Haihe River Basin in 52 years were analyzed. The NCEP/NCAR reanalysis data and historical weather charts were also applied to investigate the circulation features of the 14 typical disaster-causing rainstorm events in the basin. Frequency of the summer rainstorms in the basin has the same spatial distribution with the precipitation, while the frequency shows more significant descending trend. Three types of spatial distribution of summer rainstorms in the basin were defined, namely south-west type, north-east type and south-east type. An abrupt change of the rainstorms in the basin happened during the period from late 1970s to early 1980s. Sever rainstorms in the basin are usually caused by 5 types of circulations, namely upper level trough, lower level trough, upper level cold vortex, shear line around the fringe of subtropical high and north moving typhoon.
