Abstract: The LSAT (land surface air temperature) anomaly characteristics were abstracted by the K-value migration index method with removed background information, based on the daily minimum LSAT from China National Weather Stations. This study structured the daily LSAT characteristic data base of 2015 to 2017, including the LSAT characteristic change per day in the Central and Eastern part of Tianshan. The spatial-temporal features were analyzed and the historical earthquakes were retrespectively tested. In addition, the earthquake corresponding probability to the high LSAT anomaly and the LSAT change law before and after mid-strong earthquakes were all analyzed, this could supply some reference to the research on earthquake trend of Xinjiang China.
