Wind speedups or reductions were measured at several hundred locations, wind speeds were measured for 22.5-degree increments of wind direction at each measurement location, and the resulting information was interpolated on a geographic information system (GIS) to provide detailed contouring of the wind flow speed-ups.
 
Martin & Chock then constructed a unique phenomenological model to fit the measured data, and used that model to predict the wind speedup in all areas of Oahu, Kauai, Lanai, and Molokai, and Guam.
 
This project has provided GIS-based micro-zoning of the wind amplification.

Modeling and Analysis of topographic Wind Effects and Hurricane Damage

Using Geographic Information System Technology
 
Terrain or topographic amplification of wind speed has been a significant contributing factor in past hurricane loss experiences of Hawaii and various islands in the Pacific region. NASA-sponsored hurricane risk projects performed by Gary Chock produced new methodologies pertaining to modeling of hurricane wind speeds and topographic effects.
 
To determine speedup factors, 1:6000 scale models of selected developed portions of Kauai, Oahu, and Guam terrain were constructed based on a 10-meter digital elevation model, and tested in a boundary-layer wind tunnel to determine wind velocity accelerations (or decelerations) for a grid of data acquisition points.
