- Abstract:
- Based on the daily and monthly precipitation data (1951-2008) of Zhengzhou City, the yearly and seasonal change characteristics and abrupt change of precipitation were analyzed by using the linear trend estimate and Mann-Kendall methods. The results showed that: (1) the annual precipitation had an increasing trend in recent 60 years, and the trend rate was 14.19 mm/10 a. The precipitation change trend in each season was similar to that of annual, but the increased scope was obviously lower than the annual precipitation; (2) annual distribution of precipitation in Zhengzhou City was very uneventful, the precipitation mainly occurred from June to September; (3) annual precipitation abrupt change took place in 1953, 1958, 1964 and 1997, the precipitation abrupt change in spring and autumn took place three times, respectively, and that in summer and winter took place twice and once, respectively.
