Based on the daily precipitation data of 76 weather stations in the BeijingTianjinHebei region from 1961 to 2012, the spatial and temporal evolution of torrential rainy days is analyzed by the methods of trend and correlation analysis, Morlet and Mexicanhat wavelet, Cramer, and 〖WTBX〗t〖WTBZ〗test. The results show that the number of average annual torrential rainy days was 1.3 days, and there were three centers of high values for the torrential rainy days: the west of Shijiazhuang, Luanping, and Daming and Quzhou, respectively. There was a decreasing trend in torrential rainy days from 1961 to 2012， but the change trend was not significant. The average annual rainfall and the changing trend were not only related to the intensity of the precipitation, but also associated with its frequency closely. The greater the intensity and the frequency of rainfall, the higher the average annual precipitation was, and vice versa. The number of torrential rainy days changed abruptly in 1978 and 1996.
