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,
Wind power in Uruguay of which wind power comprised 34 percent. The national government has supported this nascent but fast-moving wind power transformation by providing a policy environment of incentives like feed-in tariffs and utility-scale bidding. The former helped incentivize small-scale installations, while the latter enabled large-scale projects. In 2008, the Uruguayan government set a target of 15% joint participation in the national electricity grid by a number of alternative renewable sources, namely biomass, wind power, and mini-hydro. Wind power alone far surpassed that proportion in the several years following the setting of that goal. Electricity generation auctions, first put forward in 2006, have
