潜热在2013年5月26日青岛地区降水过程中的反馈作用

Feedbacks of Latent Heat in Precepitation of Qingdao Region in May 26,2013

对2013年5月26—27日的青岛地区降水过程进行了数值模拟试验。结果表明,WRF中尺度模式能够较好地模拟此次暴雨天气,在暴雨过程中,受温带气旋缓慢移动的影响,造成了长时间的降水。其次,高低空急流的作用对暴雨发生发展起着重要作用;去除潜热"干"敏感试验验证了暴雨过程的正反馈作用。

A simulated test was made for a heavy rain happened in Qingdao region during May 26 to May 27,2013 by the WRF Model.The result showed that the WRF Model could simulate the precipitation process well.In the process of tile heavy rain,the long time precipitation was influenced by the extratropical cyclone moving slowly.The upper-level jet and the low-level jet played important roles in the development of the heavy rain.The test eliminating latent heat verified the feedbacks in the heavy rain process.
