Space options for tropical cyclone hazard mitigation

• We review the emerging field of tropical cyclone hazard mitigation.
• Potential space contributions to ground-based concepts are introduced.
• Cyclone mitigation concepts employing space solar power technology are discussed.
• Technology roadmaps for the space-borne concepts are presented.

This paper investigates potential space options for mitigating the impact of tropical cyclones on cities and civilians. Ground-based techniques combined with space-based remote sensing instrumentation are presented together with space-borne concepts employing space solar power technology. Two space-borne mitigation options are considered: atmospheric warming based on microwave irradiation and laser-induced cloud seeding based on laser power transfer. Finally technology roadmaps dedicated to the space-borne options are presented, including a detailed discussion on the technological viability and technology readiness level of our proposed systems. Based on these assessments, the space-borne cyclone mitigation options presented in this paper may be established in a quarter of a century.
