| [目的] 分析河南省不同主气时段累计降水量变化的周期特征。[方法] 基于运气理论，采用小波分析的方法，利用河南省1960年1月21日至2020年1月19日共60年逐日累计降水量资料，分析不同主气时段降水量变化的周期性特征。[结果] 河南省初之气累计降水量在8年时间尺度上存在5年的准周期；二之气累计降水量在9年时间尺度上存在6年的准周期；四之气累计降水量在10年时间尺度上存在6年的准周期；五之气累计降水量在17年时间尺度上存在12年的准周期；五之气累计降水量在8年时间尺度上存在5年的准周期；终之气累计降水量在25年时间尺度上存在15~16年的准周期。[结论] 河南省不同主气时段累计降水量在多时间尺度存在5、6、12或15年的准周期，初之气、四之气时段实际雨湿变化特征与五运六气理论吻合度较高。 |

| [Objective] To analyse the periodic characteristic of cumulative precipitation changes in He’nan in different dominant periods. [Methods] Based on the theory of Yunqi， using the method of wavelet analysis， the daily cumulative precipitation data of He’nan Province from January 21，1960 to January 19，2020， a total of 60 years， were used to analyze the periodic characteristics of cumulative precipitation changes in different dominant Qi periods. [Results] The cumulative precipitation of 1st Qi of the year in He’nan Province has a quasi-cycle of 5 years on the 8-year time scale. The cumulative precipitation of 2nd Qi of the year in He’nan Province has a quasi-cycle of 6 years on the 9-year time scale. The cumulative precipitation of 4th Qi of the year in He’nan Province has a quasi-cycle of 6 years on the 10-year time scale.The cumulative precipitation of 5th Qi of the year has a quasi-circle of 12 years on the 17-year time scale;The cumulative precipitation of 5th Qi of the year in He’nan Province has a quasi-cycle of 5 years on the 8-year time scale. The cumulative precipitation of end Qi of the year in He’nan Province has a quasi-cycle of 15～16 years on the 25-year time scale. [Conclusion] There are 5，6，12 or 15 years quasi-periods of cumulative precipitation in different dominant Qi periods in He’nan Province. The actual precipitation variation characteristics in the period of the 1st Qi and 4th Qi of the year are in good agreement with the theory of five evolutive phases and six climatic factors. |
