应从其大尺度气候背景场分类和中尺度模型大气边界层物理过程参数化方面进行本地化改进，使之能更好的应用于中国风能资源评估工作。

It shows that the weather classification and the atmospheric boundary layer parameterization schemes of WEST need to be modified .

大气、海洋中边界层物理过程的强非线性会对切线性模式近似（尤其是当积分时间长时）有较大的影响，从而给相应的4维变分资料同化问题的求解造成困难。

The strong nonlinearity of boundary layer parameterizations in atmospheric and oceanic models can cause difficulty for tangent linear models in approximating nonlinear perturbations when the time integra-tion grows longer . Consequently , the related 4-D variational data assimilation problems could be difficult to solve .
