Extreme Wind Speed Data Sets: Hurricane Wind Speeds

Extreme Wind Speed Data Sets: Hurricane Wind Speeds
Data Origin	This section contains data sets of simulated 1-minute hurricane wind speeds at 10m above ground in open terrain near the coastline. For details, see M. E. Batts, E. Simiu and L. R. Russell (1980), "Hurricane Wind Speeds in the United States," Journal of the Structural Division, Vol. 106, Issue 10, pp. 2001-2016.
Structure of the Data Files	There are 55 files with data for locations ranging from milepost 150 (near Port Isabel, TX) to milepost 2850 (near Portland, ME), spaced at 50 nautical mile intervals. The structure of each data file is as follows: Line 1: Milepost identifier, plus other information not needed for the analysis program. Line 2: Blank, usually. In some files, the milepost number is repeated here. Line 3: URATE and NSTRMS. URATE is the estimated annual rate of occurrence of hurricanes at this milepost, and NSTRMS is the number of simulated storms used to create the data. For all datasets included in this section, NSTRMS=999. Lines 4-1003: The windspeed data for each of the NSTRMS simulated storms. There are a total of 18 numbers on each line. The first 16 are the maximum windspeeds in 16 specified directions, beginning with NNE and moving clockwise to N. The next number is the maximum windspeed for ANY direction (i.e., the largest of the previous speeds). The wind speeds are 1-min speeds in knots at 10 m above open terrain near the coastline. NOTE: From the first 17 numbers of each line, the respective mean hourly wind speeds in meters per second at 10 m above ground over open terrain near the coastline are obtained via multiplication by the factor [0.447 m/s/mph x 1.15 mph/nmi x(1/1.24)]. The final number (18th) number in each line is the storm identifier (see the map).
Location Map	Locator map with coastal distance intervals (mileposts) marked, in nautical miles. From F. Ho, R. Schwerdt, and H. Goodyear, Some Climatolgical Characteristics of Hurricanes and Tropical Storms, Gulf and East Coasts of the United States, NOAA Technical Report NWS 15, Washington, DC, 1975.
Available Datasets	The following is the list of simulated hurricane data sets. Milepost 150 Milepost 200 Milepost 250 Milepost 300 Milepost 350 Milepost 400 Milepost 450 Milepost 500 Milepost 550 Milepost 600 Milepost 650 Milepost 700 Milepost 750 Milepost 800 Milepost 850 Milepost 900 Milepost 950 Milepost 1000 Milepost 1050 Milepost 1100 Milepost 1150 Milepost 1200 Milepost 1250 Milepost 1300 Milepost 1350 Milepost 1400 Milepost 1450 Milepost 1500 Milepost 1550 Milepost 1600 Milepost 1650 Milepost 1700 Milepost 1750 Milepost 1800 Milepost 1850 Milepost 1900 Milepost 1950 Milepost 2000 Milepost 2050 Milepost 2100 Milepost 2150 Milepost 2200 Milepost 2250 Milepost 2300 Milepost 2350 Milepost 2400 Milepost 2450 Milepost 2500 Milepost 2550 Milepost 2600 Milepost 2650 Milepost 2700 Milepost 2750 Milepost 2800 Milepost 2850 You can also download all of the files as a single zip file. Note that if you unzip this file on a Unix/Linux platform, you should use the "zip -a" option in order to obtain the correct "LF/CR" convention. Top of the Page
