STORM SURGE SIMULATION ON HURRICANE KATRINA IN GULF OF MEXICO USING AIR-WAVE-SEA COUPLING MODEL
The numerical system to study regional environment: SPEEDI-MP reproduces circulations of materials in the atmospheric, oceanic and terrestrial environments. The purposes of this system are the development of various environmental models, the connection of atmospheric, oceanic and terrestrial models and the construction of research bases for numerical environmental studies. In this system, authors developed the wind-wave-surge interaction modules for storm surge simulation and made clear its availability for storm surges in the extremely shallow water. An additional sea surface stress, the whitecap wave breaking stress, was introduced in this system to consider the processes of energy transfer from wind to current through whitecap breaking. The conducted hindcast of storm surge in this study clearly showed the importance of energy transfer path via whitecap dissipation of wind waves in the generation mechanism of mean current in the extremely shallow water. In this research, the result of thestorm surge simulation is shown in the hurricane Katrina case which considers the expansion mechanism of the surge on the continental shelf described above using the atmosphere-waveoceancoupling system.
