Abstract:

利用一个极地中尺度数值模式(PolarMM5)对北极地区大气环流进行了2005年7月17-19日48h的中尺度数值模拟研究。数值分析表明,2005年7月19日500hPa高度上,北冰洋上空北极点以东由一个冷低压控制,在极点以西则是一个暖性高压系统,在地面图上对应的则是一个气旋性环流和反气旋性环流;整个极区呈现出高(反气旋)-低(气旋)-低(气旋)-高(反气旋)的波动分布型态。选择了5个北极地区探空站与相应温度场和风场的数值模拟结果进行了对比;气象变量统计分析和垂直分布表明了数值模式很好地再现了观测大气特征,表现为小的模式偏差和较高的相关系数。在Barrow站2m处空气温度,感热通量和潜热通量具有明显的日变化特征,PolarMM5还有效地反映出此处极地逆温层和下降风的垂直结构特征。
