In-Depth Information
(Figure 5(b)) any more, using the surface anemometers and TDWR base data, windshear
alerts with magnitude ranging from +15 to +25 knots were issued for the four western
corridors. Meanwhile, areas with the microburst alerts shifted westwards and affected the
eastern corridors. WTWS issued microburst alerts of -35 knots to the four eastern corridors.
During the event, the WTWS functioned properly and was able to provide adequate
warning to the aircraft of the windshear to be expected due to the thundery weather.
