Landfalling tropical cyclones perturb Earth‘s rotation

This project explores how landfalling tropical cyclones affect Earth’s rotation. We show that as a cyclone moves across land, surface friction enables a direct exchange of angular momentum with the solid Earth, leading to short-term day-to-day rotational variations. Notably, the magnitude of this effect is comparable to that associated with major earthquakes.

Reinforcement Learning for Pre-Landfall Typhoon Intensity Control

This is a highly ambitious and challenging project. We aim to leverage cutting-edge techniques, such as reinforcement learning, to pursue our goal: exploring how to weaken typhoon intensity at the lowest possible cost by reducing sea surface temperature (SST) through mixing colder subsurface water with warmer surface water.
