| 摘 要： | 文章根据欧阳首承的演化溃变理论和信息数字化方法,对区域性暴雨与局地强降水、雷暴天气进行对比分析。利用各地探空资料,通过大气探测特性层的非规则信息,发现不同性质的降水天气在V-3θ上明显的结构性差别。即一般性降水或大面积的灾害性暴雨的对流强度,比强对流天气弱得多。并提取各类降水天气的可预报性信息,为灾害天气的预报预警提供一定参考。

| Abstract: | According to Ouyang Shoucheng＇s evolution theory and digital information methods, this article compared the regional storm rainfall with local heavy precipitation and thunderstorm weather. Using the sounding data, the irregular information of special level in atmospheric sounding was analyzed, and the obvious structural differences between the different types of precipitation were found in the V-3θ diagram. The convection intensity of general rainfall or a large area of the disastrous rainstorm was much weaker than the strong convective weather. The predictability information of the different types precipitation weather was extracted, and provided a certain reference for the forecast and early warning of disastrous weather. |
