The claim that hurricane eyes lack severe storms and precipitation despite being low-pressure regions is a matter of basic meteorological fact and everyday scientific observation, requiring no citation.
The provided retrieved papers focus on climate change health impacts, tropical cyclone modeling, rain rates, and dynamics, but none directly test or serve as primary academic receipts for the textbook meteorological definition of a hurricane eye. Because this is a standard descriptive physical fact about tropical cyclones, it is classified as common knowledge.
