摘要

For wave prediction, wind at sea is estimated with synopticrnmaps or wind observed on land. For inland sea with a short fetch,rnwind observed on land seems to be more precise and frequentlyrnobtainable than the wind estimated with large scale synopticrnmaps. However observed wind is always affected by surroundingrntopography and buildings. Wind observed on land is convertedrninto wind at sea with a presumed multiplier. Here the authorrnproposes theoretical “quantifying” estimation to replacern“presumed” multiplier, with land-sea coeffkieat as a product ofrnroughness coeffkient, topographical coefficient and contractionrncoeffkient.
