| Abstract: | An analytical form for the source function is formulated by comparing the fetch-limited approximation of the Ocean Wave Transport
equation and the empirical equation for the fetch-dependent wave forecast nomograms. The source function thus generated has
been utilised in the numerical model based on Toba’s formulation of wave transport equation and tested for the seas around
the Indian subcontinent (5°S to 25°N latitude; 45°E to 100°E longitude). The grid averaged hindcast wave heights are found
to be moderately matching with the GEOSAT altimeter measured significant wave heights of the 1987–1989 period, particularly
for waves higher than 1 meter. |
