摘要
随着交通线路的快速发展,雾对交通运输的影响越来越大,浓雾天气常常引发交通事故,给人民的生命财产造成严重损失,危害性极大。应用秦皇岛1957—2006年"气表-1"资料,统计分析秦皇岛内陆、沿海地区雾天气时空分布特征,返查1981—2000年历史天气图,得出本地区出现雾的主要天气类型,筛选出影响雾的主要天气要素,建立MOS预报方程,为雾预报及临近预警信号的发布、解除提供有利依据,达到监测、预报之目的。
With the rapid development of highway communication,the influences of the dense fog on the transportation system are becoming more and more serious.The dense fog often leads to the traffic accident,and gives rise to tremendous loss to the lives and the property of people,thus it is very harmful.By using the meteorological data from 1957 to 2006,the characteristics of the temporal and spatial distributions on the dense fog in its inland and the coastal area of Qinhuangdao City are analyzed,and by means of the historic synoptic charts from 1981 to 2000,the synoptic patterns of the dense fog are also obtained.The major meteorological elements influencing the dense fog are selected from many factors,and thereby the equation of the MOS forecast about the dense fog is set up.That will offer a strong support to the forecast of the dense fog,the issuance of early warning signal and its annulment.Therefrom,the purpose of monitoring and forecasting the dense fog will be achieved.
