摘要
从MM5模式垂直坐标定义出发,将大气静力学方程应用于整个大气,并在相邻层之间进行等温大气假设,进行求解层的高度,从而可由MM5的模拟结果中得到不同轮毂高度风场数据。对比验证表明该方法可靠,为从MM5结果获取轮毂高度的风场数据提供了另一种简便而准确计算的方法。
According to the vertical coordinate theory in MM5 model, the atmospheric static equation was applied to the whole atmosphere. With the isothermal atmosphere assumption, i. e. , the atmospheric temperature between two neighboring σ layers is isothermal, the height of σ layer was solved. And wind field data at different hubheights （height-above-ground） were acquired based on MM5. The results were proved to be reliable by comparing with the results of common method. It provided an alternative, simple, convenient method for obtaining wind field data at hub-height from MM5 results.
