This study examines how tropical cyclones affect Earth's climate system through large-scale radiative cooling of the atmosphere. While previous research has focused on how climate influences tropical cyclone formation and behavior, this work investigates the reverse relationship—how tropical cyclone activity modifies atmospheric temperature on a planetary scale. The research demonstrates that tropical cyclones produce a measurable cooling effect across the atmosphere through their radiative properties.
Why it matters
Understanding the feedback loop between tropical cyclones and atmospheric temperature is crucial for improving climate models and predictions. This finding suggests that tropical cyclones play a previously underappreciated role in regulating Earth's energy balance, which could affect projections of future climate scenarios as cyclone patterns change with global warming.
Proceedings of the National Academy of Sciences, Volume 123, Issue 21, May 2026. <br/>SignificanceAlthough the effects of the large-scale climate on tropical cyclones (TCs) have been broadly explored, it is not yet fully understood how TC activity modifies the climate system. In this study, we analyze the upscale influence of TCs on the …
