A potential explanation for the global increase in tropical cyclone rapid intensification

K. Bhatia, A. Baker, et al.

This groundbreaking study by Kieran Bhatia and colleagues explores the alarming rise in tropical cyclone rapid intensification events worldwide. The research highlights the role of human activities in increasing these intensity rates, suggesting a significant shift in the thermodynamic environments surrounding tropical cyclones, and calls for enhanced coastal resilience in the face of future climate challenges.

Abstract
This study investigates the global increase in tropical cyclone rapid intensification (RI) events. By comparing observed trends with simulations from a high-resolution global climate model, the authors find a significant increase in intensification rates, with a positive contribution from anthropogenic forcing. Thermodynamic environments around tropical cyclones have become more favorable for intensification, and climate models indicate that anthropogenic warming has substantially increased the probability of these changes. The study highlights the need for improved coastal resilience to prepare for more frequent and intense hurricanes.
