| 摘 要： | 在简要回顾经典涡度方程和全型涡度方程推导的基础上 ,比较了两种涡度方程的异同。集中讨论全型涡度方程新的物理内涵 ,证明了与稳定度和斜压性变化 (锋生、锋消过程 )相联系的内部强迫以及与摩擦耗散和非绝热加热相联系的外部强迫所诱发的涡度发展的机制。最后 ,指出了全型涡度方程的天气和气候应用前景。

| Abstract: | After a brief review on the deductions of the complete form vorticity equation and traditional vorticity equation,comparisons between the two equations are made.Particular attentions are paid to the new physical meanings contained in the complete form vorticity equation .It is revealed the mechanism for vorticity development due to the internal forcing associated with the changes in static stability and baroclinicity (frontogenesis or frontolysis),as well as the external forcing associated with frictional dissipation and diabatic heating.Finally,the application prospects of the complete form vorticity equation in weather and climate studies are discussed. |
