2009/1/19
Empirical orthogonal function (EOF) analysis in the frequency domain is extended to complex time series. EOFs are calculated from the eigenvectors of the band-averaged rotary cross-spectral matrix. Th...
Fetch Relations for Wind-Generated Waves as a Function of Wind-Stress Scaling
Canadian Atlantic Storms Program Wind-Stress Scaling Wind-Generated Waves
font style='font-size:12px;'>
2008/12/30
We present the variation that results when fetch relations for wind-generated wave spectra are sealed by the friction velocity component in the dominant wave direction rather than the magnitude of the...
The Calculation of the Dynamic Sea Surface Topography and the Associated Flow Field from Altimetry Data：A Characteristic Function Method
