WIND SHEAR CALCULATIONS FOR SMALL SHEAR LAYERS,
Abstract
Wind shear computed from data obtained at Cape Kennedy using a Jimsphere wind sensor and an AN/FPS-16 radar to track the sensor is compared with wind shear computed from three other wind measuring systems: namely, rawinsonde, rocketsonde, and Contraves cinetheodolite. This comparison indicates that the Jimsphere winds were subjected to considerable smoothing. In particular, the slope of a line on a log-log representation depicting the exponential relationship between layer thickness and wind shear is found to decrease as the wind profile is smoothed. The observed wind shear for an 82-foot layer thickness (as derived from Jimsphere wind data) is compared with the theoretical value computed using an exponential relationship between wind shear and layer thickness. Differences are less than 0.2 foot/sec for the 82-foot layer approximately 75% of the time. (Author)
