摘要
利用 1 95 5～ 2 0 0 2年甘肃省 80个站的观测资料 ,对发生在甘肃境内的 64个强或特强沙尘暴个例逐个进行了天气气候分析 ,总结了甘肃沙尘暴天气气候特点 ,沙尘暴爆发的天气类型 ,移动路径。得出沙尘暴短期和临近预报的着眼点 ,建立了甘肃沙尘暴短期预报概念模型。通过用计算机语言和模块化设计方案 ,成功设计了中国西北地区沙尘暴监测预警人机交互预报平台 ,实现了沙尘暴监测预警预报业务化。
According to the observational data from 1955 to 2002 at 80 stations in Gansu Province, 64 examples of stronger sand-dust storm occurring in the province are analyzed. Their climate, weather circumstances, influential system, influential range, the cold air source, cloudy features, and conception diagnosis are studied. The climate characteristics, the weather patterns and the moving tracks of sandstorm in Gansu province are summarized. The short-term forecasting methods of sand-dust storm are built, and the short-term forecasting conception model is given. Applying the computer language and model design method, the sand-dust storm monitoring and forecasting platform is successfully built to achieve the practical need of sand-dust storm monitoring and forecasting.
