Vertical windshear below 5.5 km is presented in this report based on 1200 GMT (Greenwhich Mean Time) observations taken at the Berlin-Templehof Airport. The vector shear calculations take into account both windspeed and wind direction changes, and represent the deviation of the windspeed and direction from one measurement point to another. Frequency distributions of differences in windspeed (scalar shear), differences in wind direction (angular differences), and vector shear were tabulated for various permutations of five pressure levels: surface, 1000mb (near surface), 850mb (1.5 km), 700mb (3 km), and 500mb (5.5 km). The 50, 90, 95, 97.5 and 99 percent values of the scalar shear, angular differences, and vector shear are also included. The results are presented by month and season along with annual means. The magnitude of the windshear in the layer surface of 1.5 km for the selected thresholds are (in sequence) 20.8, 31.4, 38.2, 44.2 and 46.1 knots for January, decreasing to 9.5, 18.7, 22.5, 24.0 and 24.2 knots for July. The smallest windshears were found for the layer surface to 1.5 km, and are (annual averages) 7.5, 15.7, 18.5, 21.6, and 24.9 knots. The largest windshear magnitudes were associated with the surface to 5.5 km layer and are 31.9, 57.0, 59.6, 76.8, and 77.7 knots, decreasing to 17.8, 32.6, 38.4, 44.8, and 49.2 knots in July for the selected thresholds.
