摘要
本文利用FGGEⅢb资料与原始方程模式对两次寒潮过程进行了数值模拟。结果表明,东亚的地形动力作用对以下天气系统有重要影响:(1)蒙古高压的生成、发展;(2)青藏高原东北边缘附近地形槽的形成;(3)兰州高压的形成和发展;(4)冷空气南下的路径。
In this paper we have investigated two cold-outbursts through numerical simulations with FGGEⅢb data and the model of primitive equation over the complex topography. It shows that the mountain dynamic effect plays important role in four weather-systems over the East-Asia: (1) forming and developing of the Mongolian High; (2) forming of topographic trough over north-east side of the Qinghai-Xizang Plateau; (3) forming and developing of the Lanzhou High; (4) the moving southward path of the cold air.
