春季大风、降雪和沙尘暴天气的信息数字化方法的分析

摘要

Using informational digital diagrams, we analyzed the snow event that occurred on Feb 26, 2006 and the sandstorm on Apr 11, 2006 in Xi'an. Results indicate that, under similar weather circumstances, different events evidently exhibit unique vertical structure features. Informational digital diagrams provide a method for transitional weather prediction,a problem for present extrapolative analysis system.%本文运用信息数字化方法结合实例分析预测2006年2月26日和4月11日发生在西安的大风、沙尘、降水天气过程.结果显示,即使天气现象相似,不同的过程也有其各自独特的结构特征和差别性.重要的是,信息数字化方法揭示了转折性天气的可预测性,而解决现行外推分析体系遇到的难题.
