A Reference Profile Based on the Average of Initial Value and Its Effect on the Prediction of Tibetan Plateau
一种依据初始场构造的参考大气廓线及对高原地区预报的影响

Usually,a reference atmosphere is used to deduce the computing error of pressure gradient in the terrain-following dynamical equations.The reference atmosphere is static,satisfied hydrostatic balance.The real atmosphere is a perturbation from the reference atmosphere.The nearer the real atmosphereis from the reference,the smaller is the prediction error.The reference atmosphere can be isothermal atmosphereor a constant vertical temperature profile;this temperature profile can also be set as horizontal avera...
