摘要
本文在分析研究了形成贵州省春季冰雹天气的 5 0 0hPa五种主要影响系统的基础上 ,以量化的影响系统特征值和无降雹条件指标为依据 ,建立了冰雹短期预报模型。预报模型的样本年代准确率为 5 7% ,经 2 0 0 1年的实际预报检验预报准确率达 5 9% 。
Short_range weather forecast model of hailfall is established in this paper,through analyzing five main synoptic influential systems at 500 hPa for Guizhou spring hailfall,by metriczable characteristic value of influential system and non_hailfall index.Prediction model acuracy for sample period equal 57%.Prediction model acuracy in 2001 equal 59%.Practical forecasting results indicate that this method is efficient.
