三维强风暴动力-电耦合数值模拟研究--模式的初步检验

利用文献「１」所发展的三维强风暴动力－电耦合模式对ＣＣＯＰＥ（Ｃｏｏｐｅｒａｔｉｖｅ Ｃｏｎｖ－ｅｃｔｉｖｅＰｒｅｃｉｐｉｔａｔｉｏｎＥｘｐｅｒｉｍｅｎｔ，１９８１）计划中７月１９日的一次强雷暴过程进行了模拟检验，并对雷暴云宏观和微观两个方面实测和模拟值进行了对比。通过分析表明，该模式基本能反映出雷暴云在各发展阶段上动力、微物理和电学特征的时空演变规律，模拟结果与实际观测结果较为接近。

The numerical simulation study with three dimensional electrification model-Preliminary simulation verification

In this investigation we compare the results of the three dimensional dynamical electrified model simulation of the July 19 Cooperative Convective Precipitation Experiment(CCOPE) case study cloud against the actual observations with respect to the cloud's electrical characteristics, as deduced from the data of two aircrafts. It is found that the 3D model reproduced the basic microphysical, charge and electric field structure of the cloud on a time scale similar to that observed. The comparability of the modeled and observed values of the field strength and charge within the thunderstorm is directly related to the proximity of the aircraft to the main active core of the cloud. The character of the some microphysics appears to be well modeled, at least at the time of observation, even if some values simulated are little high than that observed. Finally, a few problems related to the model are advanced and discussed.
