【摘要】 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．更多还原

【Abstract】 The temporal and spatial distribution of the moderate and strong earthquake above Ms6.0in China are studied. The characteristics of toroidal current and wave spectra with 500hpa before andafter earthquake are analysed. The examples of the moderate and strong earthquake are chosen in20° -- 25° N. 1 20° -- 1 23°E near Taiwan. Accordillg to analysis of the examples the activity of atmosphers wave spectrum is stimulated by thermal energy while the earthquake occurs. which results in coldair southwards before and atter earthquake. The physical mechanism of strong wind taked place withearthquake is also discussed.更多还原
