摘要
在文中推得了广义涡度守恒定律,并利用此定律在一般情况下求得了广义位势涡度定律。它放宽了最初Ertel的位势涡度定律的限制条件。并对涡度拟能、螺旋性守恒定律的物理意义作了讨论,这些定律能够描述大气运动的重要动力学性质。
In this paper, a generalized vorticity equation is derived to obtain the conservative law on generalized potential vorticity which relaxes the limitation of initial theorem proposed by Ertel. The conservative laws on enstrophy and heli-city and the physical meanings of these laws are also discussed. These conservative laws are useful for describing important dynamic properties of atmosphere motion.
