J. Hurricane Charley
From SCOOP Wiki
The following lesson uses the CH3D-SSMS (Storm Surge Modeling System) to demonstrate the effects of the different forecast tracks of Hurricane Charley on storm surge in the Charlotte Harbor region. You can select from seven different model tracks and up to eight different forecast times for each track. By comparing the various tracks, the difference in storm surge impact can be seen.
Use the following steps as a guide to the Hurricane Charley SSMS, or go through yourself and run as many simulations as you like.

Storm Surge Simulations
- Notice that you can change Forecast Time and Hurricane Track. Each Hurricane Track was generated by a different forecast model, and by scrolling through them, the differences between models can be seen on the map. Within each Hurricane Track model, the Forecast Time can be changed as well. The Forecast Time refers to the time that the model was generated. By scrolling through the different times, you can see how the models changed over time.
- First, look at the different tracks on the map to the left of the screen without running the simulations. You can either find tracks of particular interest to you, or use the following tracks to see the results of different forecasts on storm surge and coastal inundation.
Simulation 1: Forecast Time: Aug 12, 2004 00:00, Hurricane Track: OFCL
Simulation 2: Forecast Time: Aug 12, 2004 12:00, Hurricane Track: OFCL
Simulation 3: Forecast Time: Aug 12, 2004 06:00, Hurricane Track: BAMD
Simulation 4: Forecast Time: Aug 11, 2004 18:00, Hurricane Track: OFCI
- For each track simulation, you can choose to process it locally or on a grid. Execute Locally runs the simulation on your own computer. This option is best when only running a few simulations. Execute On Grid runs the simulation on a SCOOP grid. This option is best when running a large number of simulations, as it utilizes external computational power.
- After clicking Run Simulation for each case, the SSMS will show the progress of each simulation in the SSMS Inventory link. Once
the status says Completed, click Click Here under the View Results column in the SSMS Inventory link to view the storm surge plots.
- View each one of the simulations. Each simulation was chosen for the following reasons.
Simulation 1: Close to the actual track of Charley. Storm surge reaches 2.5 m in the southern part of the region, and inundation is widespread.
Simulation 2: Shows results of a Tampa Bay region landfall. Storm surge reaches 1.75 m in isolated spots, but overall maximum values stay below 1.25 m, half of what was shown in Simulation 1.
Simulation 3: Shows results if landfall would have been in far north Florida, possibly the panhandle. Because the storm track is offshore, surge stays below .2 m and inundation is minimal.
Simulation 4: Shows results if landfall would have been south of the Port Charlotte region. Because of the extra barrier of Key West and the shallow Florida Bay, storm surge is slightly higher than Simulation 3, but never exceeds .5 m.
