Abstract

Several types of satellite data collected during SEASAT-A overpasses of hurricane Fico are used to adjust input parameters in a hurricane wind prediction model. Derived winds are then used in a complex discrete spectral wave prediction model to calculate wave heights and directional spectrum distributions. Three different areas of the storm with winds ranging from 12 m/s to 23 m/s and hindcast wave heights varying from 4 m to 8 m were used to compare model normalized directional wave spectra with those from SEASAT synthetic aperture radar (SAR) imagery. The two-dimensional normalized spectral energy results from the SAR and wave model showed an average difference in peak directions of 0.9° with a standard deviation of 6.8°. Wind and wave model results are also compared with altimeter data along a subsatellite track. This study shows the value of satellite observations in model validation and, conversely, the value of the model results in verification of the efficacy of the satellite data sets. Especially noteworthy is the snapshot view of the characteristics of the storm, a demonstration of the potential power of satellite remote sensing.
