Great Lakes Nearshore Wind Predictions from Great Lakes MOS (Model Output Statistics) Wind Guidance

摘要

Marine forecasters on the Great Lakes are charged with the responsibility of forecasting wind conditions over the lakes and near the shore. Ship reports and forecast guidance are available for wind conditions which occur 5 or more n mi from shore, and wind observations are available at the coast, but little objective guidance is available within 5 n mi of the shore. The report attempts to fill that void. Winds at selected coastal stations have been compared and related to winds over the Great Lakes near those stations. Statistical relationships have been derived for various stratifications of the data, and a procedure has been developed to forecast coastal winds from wind forecast guidance over the lakes under specific conditions.
