| 摘 要： | 利用最新版的RegCM3模式,通过改变青藏高原冬季地面向大气的感热输送,分析了高原冬季感热异常对春季沙尘暴的影响.结果表明:当冬季高原地区的感热通量增大时,春季在我国上空蒙古气旋加强,位势高度西高东低,即西风加强,有利于沙尘暴增多.西风加强最显著区域在南疆盆地;西北地区降水以减少为主,这也有利于沙尘暴的增多.降水减少最显著区域在新疆东部、内蒙古和甘肃的西部;反之亦然.

| Abstract: | The influence of sensible heat abnormity over the Tibetan Plateau on sand-dust storm in spring were analyzed.Using the latest edition of the RegCM3 by changing the sensible heat transmission from surface to atmosphere.The results showed that when the sensible heat flux of surface of the main body of Plateau is increase,Mongolia cyclone strengthen in spring,and geopotential height is higher in the west than in the east,the latitudinal wind is stronger,precipitation reduces in Northwest China,and the most not... |
