- Abstract:
-
The response relationship between the abrupt temperature change and its influencing factors can provide reference for the study of the mechanism of climate change. In this paper, the clustering center and M-K inspection method were used to qualitatively and quantitatively reveal the space-time variability of temperature mutations and the response relationship between impact factors based on large space series data of average temperature, average minimum temperature, mean maximum temperature obtained from 70 weather stationsin Inner Mongolia and its surrounding areas from 1951 to 2016 and global scales. The results show that: the mutation of three kinds of temperature occurred in the period 1981—1993, of the response relations between three kinds of temperature under the different partitions and the influence factors were different, the average minimum temperature had the best correlation with the PDO, SR and wind speed, average temperature had the good correlation with PDO, MEI, SR, and the average maximum temperature had the weak correlation with PDO, MEI, SR and wind speed; spatially, the correlation between AGG(including CO2), SR and MEI was the best in the western region, followed by the correlation between AGG(including CO2), SR and MEI in the central region, and the correlation between the temperature and SR in the eastern region was the worst; in the 1980s to 1990s, along with continuous rise of all the points in the AGG(CO2), AMO, MEI value, atmospheric pressure, positive phase PDO, and SR wind speed and relative humidity, mutation of temperature of each district occurred, when AGG continued to rise for 2~9years and tendency rate reached to 0.234~0.285 W/(m2·decade),solar total radiation fell fast [-19.54MJ/(m2·decade], wind speed reduced for 3~28 years and tendency rate reached to 0.53~0.24 m/(s·decade). There had been a sudden change in average temperature. The abrupt temperature change was the result of many influencing factors. This study enriches the research results in this field and has certain reference significance for climate change research and disaster prevention and reduction.
