VOLUME 46 JOURNAL OF APPLIED METEOROLOGY AND CLIMATOLOGY OCTOBER 2007 Extreme Value Analysis of Tropical Cyclone Trapped-Fetch Waves
Many of the extreme ocean wave events generated by tropical cyclones (TCs) can be explained by examining one component of the spectral wave field, the trapped-fetch wave (TFW). Using a Lagrangian TFW model, a parametric model representation of the local TC wind fields, and the National Hurricane Cen...
