Abstract
About 5000 planes are flying at any time over most of the world's regions. Meteorological security - in presence of intense, highly-turbulent, and hail generating convective systems - is ensured by means of airborne radars operating in X-band (frequency 10 GHz,wavelength 3.2 cm) with poor spatial resolution and a strong attenuation of the microwaves by clouds and precipitation. This study addresses the difficulties and the constraints that a pilot faces, and discusses the impact of the choice of the technical characteristics of these airborne radars: how do they affect the retrieval of the convective systems and the estimation of the meteorological hazard? Numerical simulations are used and an algorithm for hail detection is presented. Some ideas for the future are presented
