芦山7.0级地震长波辐射异常分析
Reserch on the anomaly of outgoing long-wave radiation before Lushan M_s7.0 earthquake
【摘要】 分析2013年2—5月芦山地震震中区域长波辐射涡度场空间演化特征,结果显示,在芦山7.0级地震前存在涡度场明显增强的异常现象,2009—2013年同期并未出现。这一震例再次证明,在部分大震前OLR存在异常增强的变化。
【Abstract】 The characteristic of outgoing long-wave radiation eddy field from February 2013 to May 2013 is analyzed in this paper.The results show,there exist the significantly enhanced anomalies of outgoing long-wave radiation eddy field before Lushan M 7.0earthquake,which did not occurre in the same period from 2009 to 2013.It is proved that OLR increase before some large earthquakes by this earthquake case.
