摘要
文章利用三维冰雹云模式对呼和浩特地区一次冰雹天气进行模拟。结果表明:一是云水、雨水比含水量高值区可以反映出冰雹的生成位置,云水、雨水、雪水比含水量快速减小可以反映出冰雹云已经发展旺盛。霰粒子快速增长转变为冰雹,为冰雹云发展强盛贡献了主要力量;总含水量增长促使了冰雹云的发展变强。二是冰雹云生成前期及初期,在7km高空有强的风速辐散促进地面的辐合上升;冰雹云发展强盛时,强劲的上升气流促使7km高度的风速由辐散转为辐合。三维冰雹云模拟结果可为呼和浩特地区冰雹天气的预报提供参考意见。
In order to research the trigger conditions of hail and the macroscopic and microcosmic conditions of the formation of hail in Hohhot,we simulate the hail process in Hohhot by 3D hail cloud model.The results show that The high-value area of cloud water and rain water is the area of hail occurred.When cloud water,rain water and snow water decrease quickly,it means that the hail cloud has developed strongly.Also,hail cloud developed as while as graupel changed to hail,and the whole water increased.In the earlier stage of hail,there is strongly wind divergence in high level,which contributes to wind convergence in the close ground.When the hail cloud becomes strong,the powerful updraft makes the wind divergence turn into convergence in high level(7km).The 3D hail cloud model provideguidances to hail occurred in Hohhot.
