This lesson introduces forecasters to the complex and multifaceted process for creating a forecast. It also discusses how NWP fits into that process. In addition, the lesson provides a broad overview of the basic components of NWP and how they combine to produce a model ... Read more »
This lesson is focused on how a model forecast and the interpretation of that forecast, is affected by the basic design of the model. Topics include how meteorological variables are represented in grid point and spectral models, fundamental differences between hydrostatic ... Read more »
This lesson introduces the processes of model data assimilation. It also discusses the impacts of errors in the data assimilation on model forecasts and how a human forecaster can compensate for ... Read more »
This lesson describes model parameterizations of surface, PBL, and free atmospheric processes. It specifically addresses how models treat these processes, how such processes can potentially interact with each other, and how they can influence forecasts of sensible weather ... Read more »
Both the processes of convection and of rainfall formation are typically subgrid scale, and require parameterisation. This lesson examines two types of precipitation parameterisation used by models: Convective parameterisation Microphysics The lesson ... Read more »
