摘要
本文利用A.A.德罗特尼村(Дородницин)所提出的方法解出了描写积云发展的非线性微分方程组来研究一种形成、发展很快,而崩溃又很突然的积云发展过程。计算据果表明:积云的崩溃过程是从云顶开始向下崩溃的;非线性项的作用和大气层结的不稳定,在对流运动崩溃过程中起着很重要的作用;下沉运动是使积云崩溃的极重要的因素。
By the method suggested by Dorodnitsizn a solution of the simultaneous non-linear differential equations for the thermal convection are obtained.The rapid dissipation of cumulus is investigated.The cumulus dissipation starts from the cloud top and propagates rapidly downward.In this case the effects of non-linearity and unstable stratification are important.It is pointed out that the downdraft is a chief feature in the cumulus dissipation.
