摘　　要：航空运输受灾害天气影响严重,引入数值预报模式进行天气诊断分析,可提高气象信息的准确性和实用性,对航空公司采取及时、有效的运行控制决策有重要的实际意义。以发生在北京地区的一次特大暴雨天气为例进行研究,利用新一代中尺度WRF模式对当时北京区域的大气状态进行了数值模拟,对模拟结果分别从能见度、抬升凝结高度、低云碎片量、理查逊数(Ri)等方面进行诊断分析,发现诊断结果与实际探测数据有很好的一致性,因此可利用数值模式为航空器起降及巡航阶段提供气象信息保障,为航空管制人员提供更快捷、有效的气象信息,提高运行决策的效率。The severe weather has a strong effect on air transportation. The introduction of numerical weather prediction model for diagnostic analysis would be a good way for the airlines to take effective operational control decisions by improving the accuracy and usefulness meteorological information. The torrential rain occurred in Beijing area is taken for example, the new generation mesoseale WRF model is used to simulate the atmosphere and weather, then the visibility, lifting condensation level, the amount of low cloud and Richardson number are analyzed with simulation results. It is found that diagnostic results and the actual probe data are in good agreement, so the numerical model can be used to provide more efficient and effective meteorological information when aircraft are taking off, landing and cruising, which will improve the efficiency of controlling and decision-making for air traffic control officers.
