中文摘要: |
本文提出了一个计算不稳定能量E的新方法.这种方法与当前使用的计算方法间的主要不同点是它不需要完整的探空资料,只需要各层的位势高度.因此,今后根据等压面图上的资料或数值预报产品就可以计算E了.这种方法给手工和计算机计算E带来许多方便,对强对流天气和暴雨的预报是有用的. |
英文摘要: |
In this paper a new method for computing instability energy E is proposed. The main difference between this method and the method currently used is that it does not require entire sounding data except geopotential height of each level. Thus, E can be computed with data on isobaric charts. This method brings snore convenience to the computation of E by manual method or by a computer. It is useful to the forecasting of severe convective weather and heavy rainfall. |
