Geostationary Active Microwave Doppler Radar for Tropical Cyclone Monitoring

Consider implementing a geostationary active microwave Doppler radar for continuous coverage of ocean basins affected by tropical cyclones. This technology would enable forecasters to monitor cyclone structures in 3D and enhance prediction models, offering unmatched precision.

  11. Recommendation • Serious consideration should be given to the design and launch of a geostationary active microwave (Doppler radar) observation platform. • Continuous Doppler radar coverage of ocean basins frequented by tropical cyclones would : • Allow forecasters to monitor the 3D structure of tropical cyclones • offer the opportunity to assimilate cloud and mesoscale information into a cloud resolving tropical cyclone prediction model that would lead to incremental improvements in the prediction of tropical cyclone track, intensity and precipitation that could not be matched by any other foreseeable technology.
