Wind atmosphere based upon how far clouds move from one image to the next. Wind engineering describes the study of the effects of the wind on the built environment, including buildings, bridges and other man-made objects. Historically, the Beaufort wind force scale (created by Beaufort) provides an empirical description of wind speed based on observed sea conditions. Originally it was a 13-level scale, but during the 1940s, the scale was expanded to 17 levels. There are general terms that differentiate winds of different average speeds such as a breeze, a gale, a storm, tornado, or a hurricane. Within the Beaufort scale,
Full-Scale Wind Tunnel of some aviation historians, demolition of the tunnel began in 2010. Full-Scale Wind Tunnel The Full-Scale Tunnel (abbreviated FST, also known as the 30-by 60-Foot Tunnel) was a wind tunnel at NASA's Langley Research Center. It was a National Historic Landmark. In 1929, National Advisory Committee for Aeronautics began construction of the world's first full-scale wind tunnel. The design team was led by Smith J. DeFrance. The tunnel was completed in 1931 (dedicated 27 May) at a cost just under $900,000. It was a double-return tunnel capable of moving air at speeds up to 118 miles/hour (190 km/h) through its
