| 摘要 | Based on the data of daily precipitation in 11 national ground meteorological observation stations in Jining City from 1981 to 2020, the interdecadal variation, intensity, range and spatial distribution of rainstorms in Jining City were analyzed. The results show that the number of rainstorm days and the total amount of rainstorms in Jining City had significant changes among different decades. There was a continuous upward trend from the 1980s to the early 21st century and a decrease after the early 21st century. Rainstorms had distinct seasonal characteristics. They were mainly concentrated in summer, especially in July and August. In terms of spatial distribution, the frequency and intensity of rainstorms in the southeastern regions were significantly higher than those in the northwestern regions. The above results can provide a scientific basis for flood control and disaster reduction in Jining City. |
