中文摘要: 以实测资料作为初始场,用套网格的中尺度数值模式分析和模拟了与9610号热带低压相伴随的特大暴雨过程,结果发现模式对本过程的模拟效果较好,不论粗细网格,在揭示中尺度涡旋方面都具有参考价值。粗网格的模拟结果对降水落区的预报有参考意义,但降水的量级明显偏小;细网格的模拟结果不仅能较好地模拟出降水的量级,而且落区也有参考价值。此外还对造成此次特大暴雨的成因进行了分析。
中文关键词: 中尺度涡旋,特大暴雨,数值模拟,成因分析
Abstract:ased on observational data and a mesoscale numerical model (MM4),the numeric simulational results of a deep mesoscale vortex at high level which related to a heavy rain event are presented. The heavy rain caused a severe damage and lots of people death after tropical cyclone 9610 landed over Fujian province. The simulation and analysis also gave the reasons for the heavy rainfall.
