摘要
以卫星对地遥测长波辐射(OLR)信息为基础,分析了2003年8月16日巴林左旗MS5.9地震和2004年3月24日东乌珠穆沁MS5.9地震前后震中附近的45°N,120°E点位长波辐射的时序特征。结果表明,在这两次MS5.9地震前后,位于45°N,120°E点位上长波辐射(OLR)月平均值、月距平值异常特征比较明显,这种基于不同点位上的时序特征分析对地震监视和预报具体孕震区具有一定的实际意义。
Based on the information of OLR(Outgoing Long Wave Radiation) from the satellite telemetry,the authors analyzed the time sequence characteristic of Outgoing Long Wave Radiation near the epicenter at 45°N,120°E for two M_S5.9 earthquakes occurred in Balinzuoqi on 16 Aug 2003 and Dongwuzhumuqinqi on 24 Mar 2004.The authors found that month-average value and month-dispersion value of OLR at 45°N,120°E near the epicenter region,indicating obvious anomaly before and after two earthquakes.Accordingly,it is very important that having earthquake observation and predicting concrete seismogenic zone by time sequence characteristic analysis of outgoing long Wave Radiation.
