LOW-LEVEL FRONTAL WIND SHEAR FORECAST TEST

A summary report of low-level wind shear forecast tests for seven east-coast airports is provided. The tests were conducted between November 1976 and April 1977. The purpose of the tests was to verify and if possible improve upon a technique which forecasts significant low-level wind shear when a 10 F (6 C) or greater surface temperature exists across a frontal zone and/or a frontal zone has a surface movement speed of 30 knots or more. The test results indicate that the forecast technique had limited sucess for warm frontal zones and that it is ineffective for cold frontal zones.
