    摘要:

    利用 CloudSat卫星数据处理中心(Cloudsat Data Processing Center,CloudSat DPC)提供的CloudSat卫星数据、欧洲中期天气预报中心(European Centre for Medium-Range Weather Forecasts,ECMWF)提供的ERA5再分析资料和美国国家航空航天局(National Aeronautics and Space Administration,NASA)提供的 Aqua卫星可见光云图,对冬春季发生在大西洋上四个爆发性气旋个例的云微物理参量垂直分布特征进行了分析。结果表明:爆发性气旋中心云系多为层积云或积云,中心外围云系以雨层云为主,雨层云外部往往伴随着相似高度的高层云,气旋冷锋云带内以雨层云、高层云和高积云为主,冰粒子出现的最低高度与0℃等温线高度几乎重合;冰粒子有效半径随高度的增加而减小,而冰粒子数浓度随高度増加而増大;冰水含量大值区主要位于雨层云中部;液态水主要分布在高层云和层积云底部,冬季爆发性气旋个例内的液态水含量大于春季。

    Abstract:

    In this paper, the vertical distribution characteristics of cloud microphysical parameters of four explosive cyclones over the Atlantic Ocean occurred in winter and spring are analyzed by using CloudSat satellite data from the CloudSat Data Processing Center (CloudSat DPC), ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF), and satellite visible imagery from the National Aeronautics and Space Administration (NASA) Aqua satellite. The results show that stratocumulus or cumulus dominants the cloud system in the center of explosive cyclone, while the cloud system outside the cyclone center is dominated by nimbostratus. The outside of nimbostratus is often accompanied with altostratus at similar height. The cold front cloud system of the cyclone is dominated by nimbostratus, altostratus and altocumulus. The minimum height of ice particles almost coincides with the height of 0 ℃ isotherm. The effective radius of ice particles decreases with the increase of altitude, while the ice particle number concentration increases as altitude increases. The value of ice water content is large in the middle part of nimbostratus, while the liquid water content is mainly distributed at the bottom of altostratus and stratocumulus. The content of liquid water in an explosive cyclone in winter is greater than that in spring.
