摘　　要：应用中国FY-2E气象卫星与NCEP数据,计算了玉树地震前后的长波辐射与地面温度变化,并结合玉树井水温和HJ-1B卫星地表温度的结果探讨了各参量的变化特征。研究结果表明,几项参量均在玉树地震前出现了数值增高的现象。除了玉树井水温,其他几项参量的数值增高区均在临近震中的南部区域。同时,各参量增强特征出现的时间顺序与参量的内在物理属性一致,进一步证实了地震构造运动所产生的热量传递是由陆地深部传向地表再传递到大气的过程。Based on data from China＇s FY-2Emeteorological satellite and NCEP（National Centers for environmental prediction）,the variations of long wave radiation and atmospheric temperature before and after the Yushu earthquake was calculated.Meanwhile,the features of various parameters were analyzed combined with temperature data of the Yushu well and the land surface temperature data.The results show that the values of parameters increase in some areas before the Yushu earthquake,and these areas are almost located in the south of the epicenter.At the same time,the sequence and physical property of each parameter is consistent.Moreover,it is confirmed that the heat generated by seismic tectonic movement passed from the depth to the land surface and then transmitted to the atmosphere.
