- 摘要:
- 为探究微波辐射计对不同类型雾的探测预警能力,利用微波辐射计、地面自动站、观测月总薄和ERA5(0.25°×0.25°)再分析资料对西安机场2019年11月辐射雾(7日)和锋面雾(9日)不同发展阶段的温度、水汽、液态水、积分水汽含量、积分液态水含量垂直分布演变及其与能见度变化关系进行研究。微波辐射计可以准确识别两类雾的大气温度、湿度分布演变并判别逆温层变化、水汽与液态水的转化。结果表明:西安机场“11.7”辐射雾过程中,贴地逆温层与雾同步出现,成熟阶段逆温层有减弱,是因为中低空降温使上下温差缩小,逆温层消失时雾消散; “11.9”锋面雾过程没有出现逆温层。“11.7”辐射雾过程以贴地层水汽为主,液态水量很小; “11.9”锋面雾过程水汽、液态水在降水时段明显增加,起雾时段贴地层水汽密度高,液态水含量低。“11.7”辐射雾过程降温时段有水汽转化为液态水; “11.9”锋面雾过程降水时段有水汽转化为液态水,起雾时段有液态水转化为水汽。
- Abstract:
- To explore the detection and early warning ability of microwave radiometer for different types of fog, the vertical distribution evolution of temperature, water vapor, liquid water, integrated water vapor content, integrated liquid water content and the relationship between radiation fog(7th)and frontal fog(9th)in different development stages of radiation fog(7th)and frontal fog(9th)at Xi'an Airport in November 2019 were studied by using the reanalysis data of microwave radiometer, ground automatic station, monthly weather observation logbook and ERA5(0.25°×0.25°). The microwave radiometer can accurately identify the evolution of atmospheric temperature and humidity distribution of these two different types of fog and distinguish the change of inversion layer and the transition between water vapor and liquid water. The results show that during the “11.7”radiation fog of Xi'an Airport, the inversion layer and the fog appear synchronously, during the mature stage, the inversion layer weakened as cooling in the upper-middle levels reduced the vertical temperature difference, and the fog dissipates when the inversion layer disappears. The “11.9” frontal fog process did not show an inversion layer. The “11.7” radiation fog process is dominated by water vapor close to the formation, and the liquid water volume is very small. The water vapor and liquid water in the “11.9” frontal fog process increased significantly during the precipitation period, the water vapor density of the ground layer was high, and the liquid water content was low during the fogging period. “11.7” during the cooling period of radiation fog, water vapor was converted into liquid water; In the “11.9” frontal fog process, water vapor is converted into liquid water during the precipitation period, and liquid water is converted into water vapor during the fogging period.
