The innovation
The SINOPTICA prediction algorithm for the first time merges a radar based nowcasting algorithm in synergy with a very high resolution version of WRF model that assimilates GNSS, lightnings data, in situ weather stations and radar reflectivity to achieve the needed performance in forecasting severe convection. SINOPTICA develops a short-term forecasting system of severe thunderstorms affecting airports and together with the air traffic managers deploys new strategies to adjust the flights trajectories avoiding the adverse weather areas.
Into practice
Example of severe weather predicted over Milano Malpensa airport (black circle) the 11th of May 2019 and flight trajectories diverted (white lines). The large quantity of hail over the runaways caused the closure of the airport for 40 minutes and some flights delay. Nine planes were diverted to other airports. The heavy precipitation produced several floods in the city of Milan, the strong winds caused the fall of trees and billboards.
