大气中的Lagrange函数,Hamilton原理和Ertel位涡守恒

LAGRANGE FUNCTIONAL, HAMILTON'S PRINCIPLE AND THE CONSERVATION OF ERTEL POTENTIAL VORTICITY IN THE ATMOSPHERE

本文根据Lagrange质点理论,在引入Lagrange函数的基础上,应用Hamilton原理,导出了等熵大气运动中的Ertel位涡守恒定理。

In this paper, Hamilton's principle is used to obtain the conservation theorem of Ertel potential vorticity by introducing Lagrange function according to Lagrange theory.
