摘　　要：在天气学中,当复杂而开放的气候系统处于远离平衡的临界状态时,任何微小的外力扰动都有可能带来一场雪崩式的"蝴蝶效应";而天气系统的演变尽管错综复杂,其实质却主要是冷暖气团的强弱与进退,再就是月球引潮力的周期变化还能引发周期大气潮。据此推想,在月球的周期运行过程中,是交点月南、升、北、降水平引力拐点所产生的引潮力振动(方向、大小的改变),通过大气内部的动力过程,对不稳定气团可产生激发作用,从而引导冷暖空气南北进退和天气系统演变,便出现了周期大气潮和转折天气周循环。Regarding synoptic meteorology, when the complex and open climate system is away from balanceable critical state, any tiny outside force trouble can bring ＂the butterfly effect＂ as avalanche. Although the evolvement of weather system is very complicated, the essence is the intension and movement of cold and warm air mass. Moreover, the cycle of lunar tidal force will cause atmospheric tidal cycle. Therefore, we can guess that during the phases of the moon, the inflexions of horizontal gravitation of draconitic month bring vibration of tide force, which will motivate unstable air mass through the dynamic process within atmosphere, and then lead to the movement of cold and warm air and the evolvement of weather system, and the cycle atmospheric tide and week cycle of inflection synoptic appear.
