Blending Extrapolated Radar Reflectivity with Model Simulated Reflectivity for a Seamless Significant Convection Nowcast in support of Meteorological Services for the Terminal Area
This paper presents an experimental blending algorithm that merges the extrapolated and model simulated radar reflectivity. The algorithm extracts the time evolution information of the convection systems as predicted by the NWP model and integrates them with the extrapolated radar reflectivity. Preliminary performance of this blending method will also be highlighted in this paper.
The seamless significant convection nowcast would be useful for generating the trajectory-based convection forecast and for estimating the impact of the significant convection on the planned flight path in support of the ASBU Block 1 and 3 of the Global Air Navigation Plan development which has been adopted by ICAO for the next generation of civil aviation initiative in the next 15 or more years.
