摘要
用500 hPa 月平均高度对小麦雨后青枯逼熟灾害性天气进行了相关分析,并对各优势相关区进行主成份合成。用主成份变量建立的灾害预报方程,在实际使用中取得了较好的效果。
Analysis is undertaken of disastrous weather for post-rainfall forced maturity of wheat in late May to early June in relation to monthly mean 500hPa height,followed by compositing of the principal components of the preferred correlation sectors.The variables of the principal com- ponents are adopted for constructing a disaster-forecasting equation.The application shows good benefits.
