Fetch in waves
WebFeb 24, 2005 · The JONSWAP spectrum (equation 17) was developed by the Joint North Sea Wave Project for the limited fetch North Sea and is used extensively by the offshore industry. This spectrum is significant because it was developed taking into consideration the growth of waves over a limited fetch and wave attenuation in shallow water. Over 2,000 … WebThe wide-swath mode of synthetic aperture radar (SAR) is a good way of detecting typhoon/hurricane winds with a cross-polarization mode. However, its ability to detect wind waves is restricted because of its spatial resolution and nonlinear imaging mechanisms. In this study, we use the SAR-retrieved wind speed, Sentinel-1 SAR wave mode and buoy …
