Operational Test of Wave-forecasting Models During the Canadian Atlantic Storms Program (CASP)

📖 The Scoop

Description of the work to set up and test a regional spectral ocean wave model for providing real-time wave forecasting during the Canadian Atlantic Storms Program (CASP), from January 15-March 15, 1986. The ocean data gathering program (ODGP) spectral ocean wave model, a fully directional spectral model which resolves the spectra into 24 directional bands and 15 frequencies, was used for the test. A modified version of the ODGP was developed to include shallow-water equations describing wave propagation in the CASP-OC area. A large number of field measurements (both wind and wave) were collected from a number of locations on the U.S. east cost, Georges Bank, Scotian Shelf and the Grand Banks of Newfoundland. These data sets were used for the evaluation of both wind and wave predictions. This study provided a comprehensive evaluation and statistical measures of the accuracy of the operational wave model when driven by two different wind fields. In addition, a 1-D shallow-water wave model was tested within the area.
