Hurricane Eloise wave spectra

Abstract

Wave spectra from deep-water data-buoy measurements of hurricane Eloise were analyzed using the JONSWAP spectral shape formula. Correlations of α, $\text{g}\text{(}\text{Uf}{}_{\mathrm{<mtext>m</mtext>}}\text{)}$, and $\text{gH}{}_{\mathrm{<mtext>8</mtext>}}\text{U}{}^{\mathrm{<mtext>2</mtext>}}$ with $\text{gr}\text{U}{}^{\mathrm{<mtext>2</mtext>}}$ were found for values of wind speed U at the data buoy when the eye of the hurricane was at distance r away. H_s is the significant wave height, f_m the spectral peak frequency, and α is Phillip's “constant”.
