This thesis investigates the observational capabilities of the Wind Velocity Radar Nephoscope (WIVERN) mission, recently selected for Phase A studies within ESA Earth Explorer 11 program. The mission aims to address a longstanding gap in the global observation system: the lack of direct measurements of three-dimensional wind fields within clouds, particularly in the context of tropical cyclones. Unlike conventional remote sensing systems, WIVERN is designed to provide vertically resolved, in-cloud wind observations across an 800 km-wide swath with kilometre-scale horizontal resolution and quasi-daily global coverage. This represents a significant advancement in the ability to monitor storm-scale dynamics from space. The study explores WIVERN potential in two key aspects of tropical cyclone research: the reconstruction of internal wind structure and the detection of storm rapid intensification.
