Scientific Visualization
• The representation of data in a graphical and interactive way
as a method of gaining
understanding and insight into the data

Hurricane Katrina Visualization http://www.gfdl.noaa.gov/flash-video?vid=katrina&title=Hurricane%20Katrina%20Model%20Forecast
A lesson plan focused on visualizations…

Storm Surge: The real killer during Hurricanes

Storm Surge Animation http://www.nhc.noaa.gov/surge/animations/hurricane_stormsurge.swf
Storm Surge + Wave Setup
WAVE SETUP: An increase in water elevation in addition to storm surge caused by the storm’s waves

Storm Surge + Wave Setup + Tide
While tide is not included in storm surge heights, astronomical tides can drastically effect how areas of coastlines are effected during a hurricane. STORM TIDE is the combined height of the
storm surge and tide height.

Normal High Tide
Storm Surge vs. Inundation
STORM SURGE: the increase in normal water elevation caused by the storm' s winds and pressure
INUNDATION: the depth of water over what normally would be dry land, including tides, surge and wave setup

Inundation Math: High Tide
Total Possible Inundation for the House = (+2ft + 14ft + 6ft) – 12ft
Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation
Sea Level
Storm Surge = 14 ft Elevation = 12 ft

High Tide = +2 ft
Wave Setup = 6ft Inundation 10ft
Inundation Math: Low Tide
Total Possible Inundation for the House = (-2ft + 14ft + 6ft) – 12ft
Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation
Sea Level
Storm Surge = 14 ft
Low Tide = -2 ft
Wave Setup = 6ft Inundation

Elevation = 12 ft
