| 摘 要： | 运用各方面的观测资料,和非流体静力学中尺度模式第5版本对2002年12月2日发生在环渤海地区的一次低能见度天气事件进行了分析研究.利用MM5模式对本次事件进行了模拟,并计算了大气的水平能见度分布.模拟结果显示当能见度低于某一低值即1km,同时大面积爆发时,模拟结果与实况比较吻合;当能见度处于轻雾并零星分布状态时,模式还不能非常灵敏地将其有效模拟出来.

| Abstract: | In this paper,almost all available observational data and the MM5(nonhydrostatic messoscale model,version 5) model are employed to investigate a dense sea fog event occurred over the cincture of Bohai region on 2 December,2002.The result express that,when the visibility lower than 1 kilometer and burst out at the same time,the area of lower visibility calculated based upon the model outputs agrees surprisingly well with the sea fog region identified from this observation synoptic chart;when the lower visibility event occuer sporadically,the result of the model is not very well like the observation. |
