利用MM5模式对河西暴雪的数值模拟分析
暴雪 大气环流 数值模拟 诊断分析
2013/9/25
利用NCEP资料和MM5模式模拟分析了2005年3月14-15日出现在甘肃河西西部的一次暴雪天气过程。结果表明:这次暴雪天气过程产生在从低空到高空的急流轴附近;由于600~500hPa的辐合,促使形成近地面上升运动,从而使地面形成低压系统;相对湿度最大值在750~450 hPa之间,与辐合层基本一致,表明600 hPa附近有一条水汽输送通道,它与高空急流、500 hPa正涡度层、上升运动区等相吻合...

地表物理参数影响MM5模式预报的个例分析
地表物理参数 MM5 模式预报 敏感性试验
2009/7/2
据美国国家大气研究中心(NCAR)提供的和利用卫星遥感反演资料所得到的地表物理参数分别应用于中尺度数值模式MM5中,选取1998年6月28～30日的辽宁强降水过程进行了敏感性试验。结果表明卫星反演的下垫面物理参数使模拟结果更接近观测值,其优势随着网格距的减小而逐渐明显。同时,下垫面物理数的改变对于动力、热力场也有一定的影响。
