Experimental Tropical Cyclone Wind Probabilities

2004 Florida Hurricane Landfall Case Studies and 2005 Katrina and Rita Landfall Case Studies

Product Description

This web site shows experimental products that provide estimates of the probabilities of experiencing surface winds exceeding 34, 50 and 64 kt from tropical cyclones through five days. These products are based upon the tropical cyclone forecasts from the National Hurricane Center in Miami, and the Joint Typhoon Warning Center and Central Pacific Hurricane Center in Honolulu. The probability products take into account the track, intensity and wind structure uncertainties from these operational forecast centers, based on their performance from the last several years.

The purpose of this project is to demonstrate the product for the four Florida landfalling hurricanes from 2004. For each wind speed threshold (34, 50 and 64 kt), the cumulative probabilities from 0 to 12, 0 to 24, ... , 0 to 120 hours are displayed in a loop. The probablities in individual 12 hour time periods are also shown.

This work is part of a NOAA U.S. Weather Research Program (USWRP) Joint Hurricane Testbed Project. Project personnel include the following...
