Abstract:

A Web serviceWeb interface software package has been engineered to address the need for an automated means to run the Weather Research and Forecasting WRF model with four-dimensional data assimilation. The user provides a model center point and selects a domain configuration and model start hour. Global Forecast System model data is then downloaded from the National Centers for Environmental Prediction to provide the initial conditions for a model run. In addition, surface and upper-air observations are acquired and are merged with the forecast fields for the first 6 h to provide the most realistic picture of the atmosphere possible. JavaServer Faces toolkit is used to generate the user interfaces in conjunction with HTML5. Glassfish Web server is employed for Web service implementation.
