台风 Matsa (0509 ) 的进化通过从吉布斯关系导出的一个熵平衡方程以熵流动被检验，根据热力学的第二条法律。在各种各样的重要阶段的熵流动(开始，开发并且腐烂) 基于 PSU/NCAR mesoscale 模型的产量在它的进化期间被诊断(作为 MM5 知道) 。结果显示出那：(1 ) 为 Matsa 的熵流动的垂直空间分发被主要否定的熵流动在上面的层次在对流层和积极流动的大部分描绘；(2 ) 在中间的对流层(500 hPa ) 的熵流动的地证明台风的生长是否定的熵上的依赖者极大地从它的环境流动；并且(3 ) 与台风联系的重降雨的模仿的中心与大否定的熵流动的地区匹配很好，建议他们可以是为严重天气事件的重要指示物。

英文摘要：

The evolution of Typhoon Matsa （0509） is examined in terms of entropy flow through an entropy balance equation derived from the Gibbs relation, according to the second law of thermodynamics. The entropy flows in the various significant stages of （genesis, development and decaying） during its evolution are diagnosed based on the outputs of the PSU/NCAR mesoscale model （known as MM5）. The results show that： （1） the vertical spatial distribution of entropy flow for Matsa is characterized by a predominantly negative entropy flow in a large portion of the troposphere and a positive flow in the upper levels; （2） the fields of entropy flows at the middle troposphere （500 hPa） show that the growth of the typhoon is greatly dependent on the negative entropy flows from its surroundings; and （3） the simulated centres of heavy rainfall associated with the typhoon match well with the zones of large negative entropy flows, suggesting that they may be a significant indicator for severe weather events.
