Available in PDF, EPUB and Kindle. Book excerpt: Analysis of remote tower measurements of wind speed collected at the AFGL Weather Test Facility at Otis AFB, Massachusetts, demonstrated the accuracy of an offset tower system to predict the Sland Wind Shear (SWS) over a runway. The study of wind shear has been one of a continuing program of observing and short-range prediction capabilities to meet future Air Force requirements. The objective was to evaluate the relative effectiveness of two statistically-based approaches (extrapolation and screening-regression-determined equations) using offset tower data in predicting SWS speed for intervals of 0, 5, 10, 15, 30 and 60 min at two levels of severity. A surface-based runway wind observation system was used as a comparative measures.

Available in PDF, EPUB and Kindle. Book excerpt: Wind data have been analyzed to produce frequencies of occurrence of slant wind shear with respect to surface wind speed, time of day, vertical temperature gradient and wind shear direction differences. Slant wind shear (SWS) is a measurement that more closely approximates the shear encountered by an aircraft on takeoff or landing. It is computed as the wind shear between a higher level wind (in this study, 60 m) and the surface separated by a horizontal distance equivalent to that which an aircraft would traverse in descending or ascending that height. Additional study was also completed on the specification of slant wind shear along the runway through the use of an offset towersurface site system.
