Microbursts nowcasting for the Havana’s International Airport José Martí using a weather radar.

The low level wind shear has been the cause of many aviation incidents and accidents. This work is about the development of a nowcasting method for low level wind shear produced by microbursts in the Havana’s International Airport “José Martí”. Using Vesta Process software for the analysis of Casablanca’s weather radar observations, it was identified patterns of radio-echoes associated with microbursts which produced wind gusts higher than 30 knots. For that, it was analyzed the meteorological radar images considering echoes intensity in dBZ, the reached height and the morphology of them, as well as the proximity to the airport and the movement of the cumulonimbus clouds that represent damage for it and the air traffic operations. It was established a procedure to emit microbursts alerts and alarms for the airport.
