1.A global environmental atmospheric transport model(GEATM) with 1°×1° horizontal resolution and 20 layers vertical resolution is developed to study atmospheric components such as sulfur dioxide,sulfate,black carbon and dust aerosol on a global scale. This model uses a terrain following altitude coordinate and adequately considers a series of complex processes including emission,advection,diffusion,chemistry,and deposition.
初步建立了以二氧化硫、硫酸盐、黑碳、沙尘气溶胶等作为主要研究对象的全球环境大气输送模式(Global Environmental Atmospheric Transport Model,GEATM),其水平分辨率为1°×1°,垂直方向分为20层,采用地形追随坐标系,考虑了上述大气化学成分的地面源排放、平流与扩散、化学转化以及干沉降、湿清除等过程。收藏指正
2.When view distances are med/high, flying at altitude while inverted can give you a great view of the terrain below.
当能见度为中或高时，飞行高度保持在当你倒飞时时下面的地形视野良好的状态。收藏指正
3.With the basic parameters such as the axes of the dike dam, altitude and width of dike top, the slope of up and down of river, altitude and width of the road etc. It can draw up the outline of the dike dams and the intersecting line of the dam and terrain immediately.
