Historical Extreme Winds for the United States - Atlantic and Gulf of Mexico Coastlines and Great Lakes and Adjacent RegionsEntry ID: gov.noaa.ncdc.C00025
Abstract: Historical Extreme Winds for the United States are two historical publications archived at the National Climatic Data Center (NCDC). The Historical Extreme Winds for the United States are two separate publications: Atlantic and Gulf of Mexico Coastlines and Great Lakes and Adjacent Regions. Both were prepared by the NCDC for the U.S. Regulatory Commission, Washington, D.C. These publications ... contain narrative descriptions and formulae, where appropriate, on instrumentation history, measurement of extreme wind speed, categorization of station exposures, height reduction, and statistical analysis. Tabular data presented for each station are annual fastest-mile of wind speed (mph) for each year (corrected to 10 meter data for airports, 30 meters for city offices) and wind direction when available. Statistical data include computed fastest-mile of wind (mph) for return periods of 2, 5, 10, 25, 50, 100, 200,500, and 1000 years for elevations of 10 meters or 30 meters.
Purpose: To make a wide range of climatic data available to researchers and the public.

PROCESS DESCRIPTION: The initial aim of these reports was to ... extract a large set of annual fastest- mile data for all available stations in each area. To include all data, the following procedures were used: 1. For the stations of interest, published annual extremes (obtained by ordering the daily values) were checked against the original trace charts. Readings judged reasonably accurate (+2 mph) were left unchanged due to the subjectivity involved in using the measuring scale. Many cases required adjustment to a higher value. If the next highest was larger than the adjusted, it was checked for accuracy and accepted as the annual extreme if reasonably accurate. Otherwise, succeedingly lower were checked until one was found to be accurate. 2. For the period of record through June 1887 and for 1905-1911, fastest mile data were not extracted on station. Another measurement (five-minute maximum) was extracted and published. The annual five-minute maximum provided the highest five-minute speed for the year and proved to be a guide to the occurrence of the extreme fastest mile would occur at the time of the annual extreme five-minute maximum. Under certain conditions (such as thunderstorm- related winds), however, an extreme fastest mile could be included in a five- minute period with lower speed than the published annual extreme five-minute maximum. 3. For a few stations, no fastest mile or five-minute data have been extracted. For these, a visual check of all daily charts for each year was required. This was accomplished by determining an extreme for January (normally one of the windier months) and using this as a guide in visually reviewing daily charts for each succeeding month until a higher extreme was determined. This new value was then used in reviewing succeeding charts. By using some measure of extreme wind as a guide, the majority of daily charts could be eliminated with only a cursory glance. Through this process an annual extreme was determined.
