Abstract:

采用WRF模式模拟一次影响中国广东省的飑线过程,分别选取Morrison、Thompson07、Thompson09和WDM6云微物理方案实施了四组试验,每组试验包括不同云凝结核(CCN)浓度的三次模拟,称为“低浓度”、“中浓度”和“高浓度”,将模拟区域划分为深对流、浅对流和层云区域,对比分析四组试验中CCN浓度变化对模拟的总降水量、不同区域降水率和不同区域面积的影响,进一步分析了云微物理过程、动力环流强度等受CCN浓度变化的影响。发现:(1)由于不同云微物理过程与CCN浓度有着直接或间接的联系、不同云微物理过程之间存在复杂的关联、云微物理过程与动力环流之间发生非线性耦合,采用不同的云微物理方案导致模拟的CCN—降雨影响既有相似、也有差异;(2)模拟的CCN—降水影响在采用Thompson09和Thompson07方案时更显著,采用WDM6方案时最小;(3)四组模拟试验均出现CCN浓度增加延迟降水产生、初期降水减弱的情况,在模拟后期降水量也随着CCN浓度增加而减小,而飑线成熟阶段CCN—降水影响更加复杂。
