A Columbia River Entrance Wave Forecasting Program Developed at the Ocean Products Center
Author: Yongyao Zhao
Publisher:
ISBN:
Category : Marine meteorology
Languages : en
Pages : 58
Book Description
This report describes the OPC spectral wave forecasting model for the Columbia River Bar, as well as the results of some numerical experiments, on both micro and main frame computers. The model, essentially, calculates the transformation of offshore wave spectra forecasted by the OPC global wave model due to the combined effects of bottom topography and tidal currents in the vicinity of the Columbia River entrance.

A Feasibility Study on Operational Use of Geosat Wind and Wave Data at the National Meteorological Center
Author: Tsann-wang Yu
Publisher:
ISBN:
Category : Altimeter
Languages : en
Pages : 36
Book Description
The feasibility of the use of Geosat altimeter-derived wind speed and significant wave height data for operational applications is investigated. Geosat wind and wave data are compared with buoy observations for a 17 month period to determine the error characteristics as a function of various data acceptance time windows and spatial separation distances between the colocated data points. The results show that Geosat wind speed errors are sensitive to the time acceptance windows and less so to spatial separation distances, whereas Geosat wave height errors are not so sensitive to spatial and temporal separations. Three days of Geosat wind speeds and two periods of near real time Geosat significant wave height data are assimilated into the NMC's operational weather and wave forecast models. The results show that inclusion of Geosat wind speed data leads to a small impact in the southern Hemisphere, and virtually no impact in the northern Hemisphere. The Geosat significant wave height data, on the other hand, are found to have a positive impact and are extremely beneficial in short range wave forecasts over the global oceans.
