Abstract

Based on the daily data set of China surface climate data of China Meteorological Data Network (V3.0) Maqu meteorological site from 1967 to 2017. Mann Kendall and other methods are used to analyze the abrupt change of meteorological elements. The results show that the air temperature and surface temperature show an obvious upward trend in the past 50 years, which indicates that the plateau region is also continuously warming under the background of global warming, Land surface temperature is more sensitive to climate warming. The difference of sunshine hours is significant, but the overall trend is not obvious. However, the precipitation showed a slight increase, which also confirmed the warming trend of the plateau. The temperature showed an upward trend in both warm season and cold season, especially in cold season, but it kept below - 5°C thus could not form liquid precipitation; The difference of sunshine hours is small. In recent years, it fluctuates drasticly in warm season and gentle in cold season; The relative humidity in warm season is higher than that in cold season. The abrupt change analysis of meteorological elements in Maqu region from 1967 to 2017 shows that there are two abrupt changes in temperature, the time of abrupt change is about 1975-1976 and 2000 respectively, in which the abrupt change of significant rise occurred in 2000, and the abrupt change of surface temperature occurred around 2000; The wind speed decreased abruptly from 1972 to 1975; The possible abrupt points of sunshine hours are 1974, 1992 and 2002; The possible abrupt time of relative humidity is from 2004 to 2005; The possible abrupt change time of precipitation is around 1977.
