中文摘要: 用中尺度数值模式(MM5v3.7)模拟了2005年6月25—26日河南一次强降水天气过程。
模式计算的整层积分所有水凝物总含水量、模拟的雷达回波特征、24小时雨量分布、强降水
阶段雨量时变特征与实况对比均具有比较好的模拟能力,在此基础上利用模式输出的资料分
析了强降水形成的湿热力动力条件、降水区不同位置不稳定指数以及强降水区各种水凝物随
时间的变化,并用Reisner霰方案计算出的雪、霰、冰晶、雨水、云水比含量资料,对比分
析了降水初生和显著增强两个阶段云中的微物理结构特征的差异。
Abstract:Using the fifth generation PSU/NCAR Meso scale Model (MM5V3.7), a rain
storm on June 25 to 26, 2005 in Henan Province is successfully simulated. The output of
the model such as integrated hydrometeor, the Doppler Radar echo, and the 24 ho
ur precipitation are very the same like the fact. Based on the good res
ults of the model, the dynamic and thermodynamic conditions, the changes of the i
nstability index in two different areas and the hydrometeor changes are analyzed
. Besides, the differences of the microphysical structures characteristics
in the different phases of the precipitation process are analyzed by using the quality content of snow
(Qs), graupel (Qg), ice (Qi), rain (Qr), and cloud water (Qc) calculated by Reisner microphysical schemes.
