摘要/Abstract

摘要： 通过对中国国家级地面气象站的每日最低地面气温数据进行预处理, 应用K值偏移指数方法对去除研究区域多年背景信息及历史地震影响的地面气温数据进行异常特征提取, 获得天山中东段每日地面气温特征变化信息, 构建该区域2015—2017年的每日地面气温特征信息库, 研究其时空变化规律, 并进行回溯性地震检验, 得到地面气温高值异常时段的有震对应概率, 以及中强以上地震前后的地面气温变化规律。本研究对新疆地区的地震预测具有一定的参考意义。

关键词: 国家气象站, 地面气温, 偏移指数, 天山中东段, 地震

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.

Key words: National weather station, Land surface air temperature, Migration index, The Central and Eastern of Tianshan, Earthquake
