摘要
本文分析了完全的熵平衡方程中各项对暴雨的作用,作者认为先有外界能流和质流对系统的贡献,导致熵不平衡,与此同时系统内部自行调整使熵趋于平衡,从而产生气流的上升运动。因此,外界供给的能流和质流越大,系统偏离平衡态越远,造成的降水也越大。本文通过一次淮北连续暴雨过程的实例,证明了以上结论。
In this paper, the functions of each term in full entropy equilihrium equation are analysed. The author believes that the contributions of internal energy current, and quality current to system lead to entropy unbalance and at the same time, system's auto-adjusting makes entropy toward balance , which produces the upward motion of air. So, the bigger the energy current and mass current are provided from the outside, the farther the system Masses equilibrium state and the precipitation is heavy. Using a practical sample of a continuous heavy rain in Huaibei, we showed above conclusions.
