摘要: 利用2021年东北地区13个机场天气报告(METAR)、气象站观测资料和数值模式产品,对易出现高影响低温事件的机场温度预测效果进行评估,并对高影响低温区间的预测能力进行检验,以期研究影响飞机起降的低温事件的预测能力,结果表明:东北绝大部分机场温度预报偏大,偏北、偏东和高海拔地区机场的温度绝对误差和均方根误差明显大于平原地区机场;温度误差、绝对误差和均方根误差均有明显的日变化和季节变化,06—07时是机场气温预报误差最大的时段;温度高于0 ℃时,预测与观测接近,温度低于0 ℃时,预测相对集中;ZBES、ZYMH和ZYLD采用累积概率密度订正方法对机场温度预报进行误差订正后,低温事件命中率分别提升56%、14%和9%。

Abstract: Based on Meteorological Terminal Aviation Routine Weather Report (METAR),meteorological station observation data,and numerical model products for 13 airports in Northeast China in 2021,this study analyzes and evaluates the performance of CMA-MESO temperature forecasts at airports prone to high-impact low temperature events,and examines the predictability of the high-impact low-temperature interval.The results indicate that the temperature forecasts for most airports are higher than the observations except for ZYDQ,the absolute error and root mean square error of airports in the northern,eastern,and high-altitude areas are significantly larger than those in plain areas; the temperature error,absolute error and root mean square error have obvious diurnal and seasonal variations with the largest forecast errors occurring at 06:00-07:00.When the forecasts of airport temperature are above 0 ℃,they are close to observations; when below 0 ℃,the forecasts are more clustered.After applying the cumulative probability density function correction method to the airport temperature forecast error for ZBES,ZYMH,and ZYLD airports,the hit rates for low temperature events increased by 56%,14%,and 9%,respectively.
