This course will introduce the advanced applications of numerical weather prediction (NWP), mainly using the WRF model. The spectral and pseudospectral methods typically used in the global model and tropical cyclone studies will be discussed. Relaxation method used in solving the Laplace and Possion equations will be presented. Several methods for lateral boundaries used in regional models will be discussed. Class projects based on the material covered in this class will be assigned. Students taking this course are assumed to have the basic knowledge of finite-difference methods and numerical analysis.
