| 摘 要： | 给出了在广义坐标系（η）中导出的位涡方程，以及它分别在笛卡尔坐标（z)、气压坐标（p）或等熵坐标（θ）时的具体表达式。结果表明，由此得出的各坐标系的位涡方程和过去人们在各坐标系中分别推出的位涡方程一致。并且得出位涡在绝热和无摩擦的条件下守恒。

| Abstract: | A potential vorticity equation was derived in a general coordinates (p). With y representingz;;p;; or 0;; the correspponding potential vorticity equation is identical with the previous potentialvorticity equation in different coordinates respectively. The potential vorticity is conserved under theadiabatic and frictionless conditfons independently of the chosen coordinates. |
