Mississippi/Louisiana Gulf Coast Yan Ding NCCHE, University of
Mississippi, 6/4/2011
Slide 2
Computational Conditions for Modeling Storm-Surge Tide
Hypothetical Hurricane: Central Pressure = 970 mbar, Max. Radius =
50km, Moving speed = 25km/h, Direction = from SE to NW Tide: M2,
Tidal Amplitude = 0.2m Tide Hurricane
