中文摘要: 用石家庄1955~2002年11个站的温、湿、风、云资料,查找高温个例,统计分析了高温当日及高温前一日的气象要素特征;还普查了1972~2000年的历史天气图,系统地总结归纳了石家庄高温的气候特点和高温出现的高空、地面形势场特征。在此基础上结合各家数值预报产品提取预报指标,建立了经验指标法定性预报流程和高温预报方程及定量预报流程,对40℃以上高温有了较好的预报能力。经业务使用检验,能显著提高石家庄高温预报准确率。
Abstract:Based on data of air temperature, humidity, wind, cloud at eleven weather stations from 1955 to 2002 in Shijiazhuang, high temperature events are investigated. The synoptic and climatic characteristics of high temperature events are analyzed. Prediction equation and quantitative forecast flow are developed, and the high temperatures (≥40℃) can be more successfully forecasted.
