Prediction of Slant Wind Shear with an Offset Tower Observation System.

Abstract

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.
