wind-erosion basin

The Arid region of China ( includes xinjiang province, Hexi Corridor of Gansu province, Qaidam basin and the west of Helan Mountain), with drought climate and strong wind, is the most rigorous region of eco-environmental problems.

我国干旱区（包括新疆全境、甘肃河西走廊、青海柴达木盆地及内蒙古贺兰山以西地区）气候干旱、风大沙多，是我国生态环境最为严酷的地区。

The wind speed basically followed empirical Ekman spiral curve with height distribution. These results could find their application in Sichuan basin universally.

风速随高度分布基本遵循经验爱克曼螺线，这一经验公式可在四川盆地内推广应用。

An improved three dimensional quasi static model is developed from conservation equation for momentum and mass in a terrain following coordinate system, to simulate the winter wind field and temperature field over the eastern part of the Lanzhou basin.

采用地形追随坐标系下具有1.5阶精度的三维准静力模式，模拟兰州东部地区的风场和温度场。

The avalanche of water fills the rock basin with spray and consequent wind.

奔腾的水流注入到岩石池中,泛着飞沫,激荡生风.
