本研究选取2009—2015年云南地区观测连续、稳定的水温观测资料共34项,采用异常过程和从属函数分析方法联合提取异常,同时选用同时期发生在云南省内的21次17组(发生在1个月内的2次地震视为1组)M_s≥5.0地震作为研究样本,分析水温异常与地震的关系。

In this study, a total of 34 observations of continuous and stable water temperature in Yunnan area from 2009 to 2015 were selected. Anomalous processes and subordinate function analysis were used to extract abnormalities. At the same time, 17 groups of 17 occurred in Yunnan Province during the same period Two earthquakes within 1 month are regarded as one group) M_s≥5.0 earthquakes as a sample to analyze the relationship between water temperature anomalies and earthquakes.
