Hydrometeor model enhancement for Doppler polarimetric method of atmospheric hazards detection

Detection of atmospheric hazards that influence onto flight operation is important task of modern radar meteorology. It requires the development of real time methods and algorithms for operational atmospheric hazards detection including wind related phenomena. Many known approaches and algorithms to wind related phenomena detection and estimate operate with averaged data that complicate real-time measurements. For Doppler polarimetric radar, the most developed are models related with motions of water droplets in precipitation and clouds. In this paper the progress in model development introducing water-air-ice mixture additionally to the raindrops is done. Spectral-polarimetric parameters that include Doppler co-polarized spectra, spectral differential reflectivity and correspondent slope lines are studied and analyzed at different wetness parameters and different turbulence intensity values.
