从我国6.0级以上中、强地震的时空分布状态入手,选择台湾附近(北纬20°─25°,东经120°─123°)的中、强地震作为样本,对地震前后的500hPa环流特征和500hPa波谱等进行了分析,发现地震发生时产生的热能能够激发大气波谱的活跃和增幅,从而引导了地震前后冷空气的南下,进而讨论了地震爆发往往伴随强风现象的物理机制.
Beginning with the temporal and spatial distribution of moderate and strong earthquakes above M 6.0 in China, we selected medium- and strong earthquakes near Taiwan (latitude 20 ° -25 ° north and longitude 120 ° -123 ° East) as samples to study the characteristics of 500hPa circulation before and after the earthquake And 500hPa spectrum. It is found that the thermal energy generated during the earthquake can stimulate the activity and increase of the atmospheric spectrum, and guide the cold air southward before and after the earthquake. Then the physical mechanism of the strong wind blows is discussed.
