Thirdly, short term distribution of wave period conditional on the large individual wave height in a sea state is given by multiple regressions...

... Abstract The objective of this work was to develop a robust methodology for deriving hurricane wind, wave, and storm surge design criteria for offshore structures in the Gulf of Mexico. The hurricane simulation model takes advantage of detailed historical database of Gulf of Mexico hurricanes...

...-inertial oscillations generated by the storm and the eddy front leads to accelerated vertical and downstream propagation of near-inertial oscillations. This process produces increased amounts of near-inertial energy at depth and, consequently, stronger currents. Due to its nature, the effect...

.... The influence of sea surface temperature and mixed layer depth on storm intensity is accounted for explicitly. The model is validated by comparing the results of a 100,000-year simulation to historical storm data. Using 300,000 years of storms derived from the model, wind criteria across the Gulf has been...
