Gustav-Ike tracks superimposed by MODAS sst (Sept. 1, 2008)

Gustav made landfall at Louisiana on 1 September and Ike at Texas on 13 September. Tracks are colored by hurricane wind speed (m/s).

SST and SSH hindcast during the passage of Gustav, Ike

This animation illustrates simulated SST and SSH in the GoM for Aug. 16-Sep. 28, 2008. Wind vectors are superimposed.

Mean sea level time series from tide gauges

This figure illustrates mean sea level time series observed at 10 tide gauges (shown in the right panel) during the passage of Gustav and Ike.

Volume transport through two channels

This figure depicts volume transport through inflow and outflow channels of the Gulf of Mecico during the passage of Gustav and Ike and depth-averaged temperature.  Significant transport decrease is noted. This figure can be compared to Figure 4 in Zamudio et al. (2008). The question is what makes the decrease.

This figure illustrates a comparison between model and satellite sst in a box in the central GoM, which well demonstrates the hindcast capability of model. Significant surface cooling (1.5-2.5C) is noticeable after the passage of Gustav and Ike.

Heat flux through Yukatan and Key West Channels

This shows time series of heat flux due to advection (top), diffusion (mid) and advection+diffusion (bottom) for 8/16/2008-9/28/2008. Keywest channel (black) shows greater values than Yukatan channel (blue).
