摘要:
按欧阳首承教授溃变原理的V-3θ非规则结构信息分析方法,对三明2006~2012年133个暴雨日进行了检验分析和预测应用。结果表明:暴雨日前08时或20时三明周边探空站的V-3θ结构信息图对锋面暴雨、锋面暖区暴雨、低空低涡暴雨、热带气旋暴雨可分析出明显的前兆特征,对副高边缘暴雨(包括副高南界的东风波)部分可分析出明显的前兆特征,以上五个暴雨型表现出的共同的基本机制为对流层高层出现超低温现象,3θ曲线的非均匀结构,较好的水汽条件和整体顺滚流。
Abstract:
133 rainstorms occured in Sanming from 2006 to 2012 were analyzes and forecast by V-3θirregular structure information analysis method of degeneration theory developed by Professor Ouyang. The results show that obvious precursory characteristics of frontal rainstorm, warm section heavy precipitation, vortex heavy rainfall and tropical cyclone torrential rain can be shown and analyzed by using the V-3θstructural information graph of sounding station around Sanming from 08:00-20:00 before the rainstorm day. In addition, heavy rain events at the edge of West Pacific Subtropical High (including the easterly wave of southern edge of Subtropical High) can be partially shown and analyzed as well. The common basic mechanisms of these five types of rainstorm as described above include the ultra-low temperature at the troposphere top, non-uniform structure of 3θ curve, good moisture conditions and the clockwise tumble flow.
