Webminimum wind speed for “upset.” Our purpose was to use the results of the wind tunnel tests to corroborate the field study of 291 vehicles actually exposed to tornadoes, presented in section 3.2. The sedan was most vulnerable to upset with wind from 140 degrees (rear quarter) when upset occurred at a wind speed of about 52 m/s (115 mi/hr). WebGood places for wind turbines are where the annual average wind speed is at least 9 miles per hour (mph)—or 4 meters per second (m/s)—for small wind turbines and 13 mph (5.8 m/s) for utility-scale turbines. Favorable sites include the tops of smooth, rounded hills; open plains and water; and mountain gaps that funnel and intensify wind. gps wilhelmshaven personalabteilung
