- Abstract:
- Trend analysis, cumulation anomaly analysis, signal-to-ration test and Mann-Kendall test were used to analyze air temperature and precipitation annual variability in Xiuwen of Guizhou from 1963 to 2018. It is found that in recent 55 years, the annual mean temperature was 13.8℃, it rose significantly, increased by 0.11℃/decade, and an abrupt change from low to high occurred in 2000, climate change was more pronounced at the lowest temperatures; the annual precipitation was 1 144.8 mm, it showed the significantly decreasing trend in 55 years, decreased by 31.8 mm/decade; the precipitation trend of spring, summer and autumn significantly reduced after 1980, and it did not significantly reduced in winter; annual distribution of precipitation in Xiuwen area was very uneventful, the precipitation mainly occurred from May to September, and the precipitation in summer basically accounted for 50% of the annual precipitation; the abrupt change of precipitation occurred in 1980.
