中文摘要:
      在雹云物理和防雹研究中需要有一个较简单的模式。现有的较简单的一维模式由于没有考虑融化作用对雹分布谱截距的影响,严重歪曲了零度层以下雹谱应有的物理图象,使人们难以相信模拟的结果。为此,我们设计了一个能反映融化对冰雹双参数分布谱演变影响的一维时变模式。计算结果表明本模式较为合理地描述了零度层以下的雹谱演变过程。利用这个模式,计算了一批例子,研究了温度层结,湿度,成雨能力,及冰雹浓度对雹云发展过程的影响,得出了一些有意义的结果。
英文摘要:
      In the general parameterization models of hailcloud the value of intercept of hailstone size-distribution was defined by a constant and the melting effect on the decrease of hailstone number had not been considered, so that the feature of hail microstructure at below 0℃ level was distorted. To improve the model we have developed a numerical model of a hail-bearing cumulus which is one dimensional and time-dependent, with a biparameter size-distribution associated with the melting of hailstones. The computed results of this model show that the feature of hail-microstructure below 0℃ level is more appropriate and that the air humitity can influence cloud's updraft distribution profile which is important for the formation of hail or rain.
