| 摘 要： | 利用1960—2017年降水资料,通过统计分析、累积距平法和小波分析,研究58年来含山县降水量和降水频次的变化特征。结果表明,自1960年以来,含山县降水量、降水频次总体而言均呈上升趋势,同时表现出周期振荡变化。通过小波分析发现,在年际变化过程中,含山县降水量存在着15～25年、8～10年、3～5年的周期振荡特征,降水频次存在着18～32年、8～17年的周期变化特征。

Analysis on the Characteristics of Precipitation Change in Hanshan County from 1960 to 2017 |
| |
| Abstract: | Using the annual precipitation data from 1960 to 2017, the variation characteristics of precipitation and precipitation frequency in Hanshan County were studied in the past 58 years by statistical analysis, cumulative anomaly method and wavelet analysis. The results show that since the 1960s, the precipitation and precipitation frequency in Hanshan County has generally increased, and it shows cyclical fluctuations. Through wavelet analysis, it is found that during the interannual variation, the precipitation of Hanshan County has periodic fluctuation characteristics of 15-25 years, 8-10 years, and 3-5 years, and the frequency of precipitation has the characteristics of periodic variation of 18-32 years and 8-17 years. According to the results of analysis, the precipitation in Hanshan County in 2018 is predicted, and the frequency of precipitation is in a multi-period. |
