Using complex climate models, Chavas studied hypothetical scenarios such as land surface changes to understand their effects on severe weather. The latest findings, published in the Proceedings of the National Academy of Sciences, show how surface roughness in South America and the Gulf of Mexico affects hurricane frequency.
Thus, the smoothness of the South American surface increases the likelihood of hurricanes, while the roughness of the Gulf of Mexico surface reduces hurricane activity in North America—at least that’s what the models suggested.
The study not only deepens our understanding of hurricanes, but also provides insight into how future climate change could impact “global-scale severe weather dynamics.”
