中文摘要:
      本文考虑了整个对流气柱内上升气块的浮力的平均效应,从而推导出一个便于日常作对流预报用的平均不稳定能量指标S(H)。使用1959—1962年7—8月长沙的资料对S(H)指标进行检验,结果表明:S(H)指标很好地指示对流生长的规律性。
英文摘要:
      Based on the fact that all particles in convective air columns must be lifted in the development process of convection, an average buoyant force of these lifted particles is considered in deriving a mean unstable energy index for convective forecasting which is convenient for practical use in forecasting.Using the data of July and August from 1959 to 1962, for Changsha the tested results for index are satisfactory.
