Course Content (Syllabus)
Introduction: general characteristics of atmospheric numerical weather prediction models, historical aspects, applications. Equations: The primitive equations, prognostic and diagnostic equations, hydrostatic and non-hydrostatic numerical weather prediction models. Numerical Methods: Round off and truncation errors, finite difference schemes, linear advection equation, diffusion equation, non-linear advection equation, stability, aliasing and non-linear instability, spectral methods, time differencing. Grids: The grid point, horizontal differencing, staggered grids of Arakawa, Gaussian grids, boundary conditions, choice of the model domain, nesting, vertical coordinates, boundary conditions over land/sea surface (land/sea mask, topography, land use). Physical parameterizations: Surface energy balance, soil schemes, surface moisture and heat fluxes, viscous sublayer, microphysical schemes, convection schemes, treatment of snow. Ensemble Forecasting: the gridded analysis, operational numerical weather prediction, data assimilation, forecast errors, ensemble foreacasting methods, singular vectors, available forecast products. Analysis of the latest available numerical weather forecasts.
