Short Summary

This study, utilizing global drifter data, reveals that tropical cyclone-induced sea surface cooling is significantly weaker than previously estimated by microwave satellites and climate models, despite regional sea surface warming trends fueling cyclones at approximately twice the tropical mean rate.

Objective

• To re-evaluate the magnitude of tropical cyclone-induced sea surface cooling using in-situ observations and compare it with previous estimates from satellite data and climate models, while also assessing the influence of broader sea surface warming trends on tropical cyclones.

Study Configuration

• Spatial Scale: Tropical storm-affected areas.
• Temporal Scale: Contemporary warming climate, focusing on sea surface warming trends.

Methodology and Data

• Models used: Not explicitly stated as used by the study for its primary findings; however, the study contrasts its results with estimates from state-of-the-art climate models.
• Data sources: Global drifter data (primary observational source); contrasted with estimates derived from microwave satellites.

Main Results

• Tropical cyclone-induced sea surface cooling in storm-affected areas is considerably weaker than indicated by previous estimates derived from microwave satellites and state-of-the-art climate models.
• Despite an enhanced self-induced cooling mechanism driven by greenhouse warming, tropical cyclones are fueled by a localized sea surface warming trend that is approximately double the tropical mean warming.

Contributions

• Provides a novel, observation-based re-evaluation of tropical cyclone-induced sea surface cooling, challenging long-standing estimates from remote sensing and climate models.
• Highlights the critical role of regional sea surface warming, occurring at an accelerated rate, in fueling tropical cyclones, even amidst their self-induced cooling effects.
• Offers new insights into the complex interaction between tropical cyclones and the upper ocean in a warming climate, with implications for understanding cyclone intensity and future projections.
