摘要
利用云南多震区的地面气温资料对上世纪 90年代在云南发生的中、强震及在周边发生的强震进行了分析研究 ,发现中、强地震前热异常现象 (震中附近地面气温月距平值即ΔTij≥ 1 0成片出现 )是普遍存在的 :强震前震中及相邻地区春季回暖明显早于其相临年份 ;与卫星遥感OLR资料相比地面气温资料有其自身的优点。
The middle and strong earthquakes occurred in Yunnan and its adjacent areas in the 1990s are studied by using the ground temperature data in Yunnan earthquake areas and it is found that there were generally thermal anomalies(monthly anomalous value of ground temperature near the epicenters ΔT ij ≥1 0)before middle and strong earthquakes and the date getting warm again in the epicenters and their adjacent areas in the Spring before strong earthquakes was earlier than that in other years.The ground temperature data have a unique advantage as compared with OLR data of satellite remote sensing.
