中文摘要: 应用耗散结构理论,提出了大气中“湿熵"的具体计算公式和“相对湿熵"的概念,推导出了便于在大气中实际应用的总熵流表达式。结合河北省两次暴雨及特大暴雨天气过程,初步分析归纳了熵的演化与强对流暴雨和落区的关系;熵的演化与台风低压引发的暴雨和落区的关系,指出了两种暴雨过程的共同点和不同点;对台风低压的移动规律得到了某些有益的认识。

Abstract:Based on the theory of dissipation structure,the calculation formula of atmospheric Wet entropy and the conception of relative wet entropy have been presented. The formula of general entropy flow which is easy to be applied in atmosphere has been calculated. Two weather processes of heavy rain and rain gust in Hebei Province were taken, the entropy evolution and its association with the placement of severe convection storm and with the placement of heavy rain of typhoon low have been analysed. The common ground and difference of the two heavy rain events have been presented. The moving law of typhoon low has been recognized.
