摘要
应用了美国国家环境监测中心的NOAA卫星长波辐射(OLR)月际资料。用月距平、涡度计算等处理方法,对2007年5月5日西藏日土—改则MS6.1地震前后的OLR资料进行分析,结果发现在震前的2个月,震中附近地区出现明显的高值辐射变化,其高值中心位于阿尔金断裂和西昆仑地震带的交汇部位,异常形态呈孤立的"V"字形,分析认为这种现象可能与地震前的热动力状态有关。
According to the monthly datum of OLR recorded by NOAA satellite of American national environmental monitoring center, we used anomaly method, vorticity method and so on to analyze the OLR datum before and after Ritu-Gaize Ms6. l earthquake occurred on May. 5, 2007 in Tibet. the result shows, high value radiation change occurred in the epicenter region 2 months before the earthquake, the high value center lies in the region between Arjin fault and Xikunlun fault, and its shape look like ＂V＂ letter, we think the phenomena is relative with thermodynamical state before earthquake.
