For example, a westerly wind blows from west to east. Degrees: Alternatively, the wind can be reported in clockwise degrees counting from the north, which corresponds to 0°. Thus, 90° is equivalent to the east, 180° is equivalent to the south, and 270 ... WebThe wind is simply the horizontal movement of air. Wind measurement is composed of two complementary parameters: its speed (or force) and its direction. The units of measurement of wind used in the UK are km/h or m/s for its speed, and knots (1 knot = 1.852 km/h) which are mainly used by sailors and pilots. bitcoin flyer
