摘要
2019年10月31日至11月2日六盘山气象站发生了2次大雾天气过程,为初步了解我国北方高山大雾宏微观特征,基于六盘山国家基准气候站和院内安装的FM-120雾滴谱仪的观测数据,对2次大雾天气过程的雾滴谱分布特征进行综合分析。结果表明,六盘山大雾天气发生发展、爆发和消散迅速,爆发阶段持续时间长;气温、相对湿度、风和雾滴特征的变化早于大雾消散,同时辐射-平流雾在发生发展和消散前能见度与气象要素和雾滴浓度、大小呈反增长关系,而平流雾与液态水含量、中值体积直径、有效直径呈反增长关系;平流雾的粒子数浓度小于辐射雾,而液态水含量大于辐射-平流雾,但整体六盘山粒子数浓度较低。
Two fog weather events of different nature occurred at Liupan mountain Meteorological Station from October 31 to November 2,2019.A preliminary understanding of the characteristics of alpine and foggy weather in northern China is based on the meteorological elements of the Liupanshan National Reference Climate Station and the installation in the hospital.The fog droplet spectrometer observation data is used to comprehensively analyze the characteristics of different types of fog droplets.The results show that the heavy fog weather in Liupan mountain develops rapidly,erupts and dissipates,and the duration of the eruption phase is long.The changes of meteorological elements and fog droplets are earlier than the dispersal of the fog.At the same time,the visibility and meteorological elements and fog droplets of the radiant fog before the development and dispersal occur.Concentration and size show a reverse growth relationship,while advection fog has a reverse growth relationship with liquid water content,median volume diameter,and effective diameter;the advection fog has a smaller particle concentration than radiation fog,and the liquid water content is greater than radiation fog.But the concentration of particles in Liupanshan is relatively low.
