列叙了部分强震前后短期内的异常气象情况，探讨了其与强震间的机理，并结合1976年松潘7．2级地震波及汉中地区引起的破坏，讨论了异常天气（主要指降大雨、雪）带来的灾害叠加问题。对编制防震减灾规划和地震短临前兆探索，无疑是有益的。
The author describes the abnormal meteorological conditions before and after some strong earthquakes and discusses the mechanism between the earthquakes and the strong earthquakes. Combining the damage caused by the Ms7.2 earthquake in Songpan and the Hanzhong area in 1976, it discusses the abnormal weather , Snow) brought over the issue of superposition of disasters. It is undoubtedly beneficial to formulate plans for earthquakes and disaster reduction and exploration of short-term and short-term earthquakes.
