Analysis of the Characteristics of Temperature and Precipitation Changes in Funing County,Yunnan from 1957 to 2022
Using linear trend rate,M-K abrupt change test,etc.,the change characteristics of temperature and precipitation in Funing Coun-ty from 1957 to 2022 were analyzed.The results showed that the annual maximum temperature,annual mean temperature,annual minimum temperature,extreme maximum temperature and extreme minimum temperature in Funing County had all shown significant increasing trends in the past 66 years.Among them,the average maximum temperature had increased mainly due to the increase in summer temperature,the aver-age mean temperature had increased mainly due to the increase in autumn temperature,while the average minimum temperature had increased mainly due to the increase in winter temperature.The trend of annual precipitation was not significant,and the precipitation in spring,summer and autumn showed a slightly decreasing trend,while the precipitation in winter and the daily maximum precipitation showed a slightly increas-ing trend,and the trend was not significant.The abrupt change test results showed that the annual maximum temperature,extreme maximum temperature,extreme minimum temperature and annual precipitation had undergone abrupt changes in 2013,2009,2000 and 1986 respective-ly,while the annual mean temperature,annual minimum temperature and daily maximum precipitation had not shown obvious abrupt changes.
