长波辐射在地震预报中的应用

APPLICATION OF OUTGOING LONG-WAVE RADIATION TO EARTHQUAKE PREDICTION

摘要:

本文应用卫星接收的地气系统射出的长波辐射资料,分析计算了几次地震前长波辐射的异常变化。分析结果表明,云层对长波辐射月平均值的影响不大,所以长波辐射的大小可以反映下垫面的热状况。地震发生前,长波辐射的值都异常升高。因此,长波辐射资料的异常变化在地震的短期和临震预报方面有应用前景。

Abstract:

By using the data of outgoing long-wave radiation (OLR),received by the satellite,this paper calculated the anomalous variation of OLR before several earthquakes.The results show that the effect of cloud layer on the monthly mean value of OLR is only a little;the OLR value can reflect the heat state of the ground; before the earthquakes,the OLR value rises obvious-ly.Therefore, the anomalous variation of OLR is of applied prospect for short-impending earthquake prediction.
