Abstract:The 6 geostationary and polar-orbiting FENGYUN meteorological satellites in orbit have formed a layout serving the Belt and Road Initiative and the service mechanism of FENGYUN satellite data for disaster emergency and mitigation is established. The study summarizes the methods and latest progress of tropical cyclone monitoring over the Belt and Road area by FY-2H, FY-4A, and FY-3C/D. Moreover, the major tropical cyclones in 2018 and 2019 are listed and some typical cases are revealed in particular, including the cyclones that caused heavy disasters, cross-ocean cyclones, and two/three/four coexisting cyclones. The results show that in the tropical cyclone monitoring over the Belt and Road area by FENGYUN satellites, it is of great significance for the monitoring and forecasting of the life cycle of tropical cyclones when combining the evolution of tropical cyclones with the observation of different instruments onboard the meteorological satellites and applying corresponding instruments in accordance with different stages of tropical cyclone.
