Wind speeds usually mean the movement of air in an outside environment, but the speed of movement of air inside is also important in many cases, including weather forecasting, aircraft and maritime operations, construction and civil engineering. High wind speeds can cause unpleasant side effects, and strong winds often have special names, including gales, hurricanes, and typhoons. The highest wind speed ever measured on earth, 253 miles per hour, was recorded on Barrow Island, Australia.
