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,
United States Wind Energy Policy offshore leases. The first (3.6 GW) went to Deepwater Wind near Massachusetts and Rhode Island, the second (2 GW) went to Dominion Virginia Power 23 miles off the Virginia coast, and the third (1.45 GW) went to US Wind 10 miles off the coast of Ocean City, Maryland. United States Wind Energy Policy Modern United States Wind Energy Policy coincided with the beginning of modern wind industry of the United States, which began in the early 1980s with the arrival of utility-scale wind turbines in California (see Altamont Pass). Since then, the industry has had to endure the financial uncertainties
