"WebTurbine blades vary in size, but a typical modern land-based wind turbine has blades of over 170 feet (52 meters). The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field. When wind flows across the blade, the air pressure on one side of the blade decreases. " - How wind direction described

WebWhen the wind is perpendicular to the isobars (so parallel to the pressure gradient), the cross-isobar angle is 90º. When the wind is parallel to the isobars (and perpendicular to the pressure gradient, the cross-isobar angle is 0º. An example of a cross isobar angle used to show the wind’s direction relative to the isobars. WebIn Figure 1(a), the wind speed dependency of the radar backscatter is plotted for wind speeds between 2 and 18 m/s. For this plot, the mean backscatter at range distances between 330 and 1650 m was retrieved considering the entire azimuth of the radar, which is equivalent to all wind directions.It can be seen that the radar backscatter increases with …
