利用MM5中增加的双参数显式云物理方案模拟了西北地区一次层状云降水过程，模拟结果显示对小雨的预报评分较高，对中雨以上评分低而且位置有一定偏差，即对层状云降水模拟效果较好。

Its generated mechanism is that poten-tial instability is touched off by the convergent and thermodynamics near theground in the favourable weather controlled by trough of high altitude.Thatmakes effective potential energy release greatly, forming strong convection.Meanwhile, intensive storms with convection are occurred because of the plentyof moisture flowing into the basin and favourable topograph...

吐鲁番盆地的大降水具有降水时间短、强度大、范围小，雨量集中等特点，它的发生机制是在高空低槽控制的有利天气形势下，地面动力辐合作用和热力作用触发了大气中的潜在不稳定结构，使得大气有效位能大量释放，形成强烈的对流；同时，有充沛的水汽输入盆地，在有利地形条件下，产生强对流暴雨。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
