滞弹性系统中对称扰动的涡度方程的特征分析

Analysis of symmetrically disturbed vorticity equation in anelastic system

采用滞弹性近似下的三维中尺度大气动力学方程组,得到了滞弹性系统中对称扰动的涡度方程,并对涡度方程中各物理量进行分析。研究结果表明,相对于浅对流的情况而言,深对流情况下对称扰动的涡度方程较为复杂,滞弹性近似对于研究深对流运动是有效的。

According to anelastic approximation of the three-demensional mecoscale dynamic equations, this paper acquires symmetrically disturbed vorticity equation in anelastic system, and analyses components of the equations. The results show that the symmetrical disturbed vorticity equation of the deep convection is more complicated, in comparison with the condition of low convection,and the method of anelastic approximation is usful for studying the deep convection.
