摘要
首先定义熵动量并对其取旋度,再根据波尔兹曼熵公式,推导出二维平面几率流体涡度熵的时变方程,最后根据地球大气的实际,对熵变方程作出了物理解释,并且提出了一个诊断天气系统变化的方法。
At first, we define entropy-momentum and take its rotation.Secondly, based on the equation of Boltzmann entropy, derive the time-change equation of the vortex entropy of probability fluid on a two-dimensional plane.At last, based on earth atmospheric practice, make some physical explanations of the time-change equation of entropy, and advance a diagnosis method of weather-system change.
