Scientists have known for years that Florida receives more rainfall in decades when North Atlantic waters are warmer than average, but the UM research team wanted to learn more about this interaction to help communities prepare for a wetter future. This study showed that ocean temperatures are most influential on Florida precipitation in late summer, during the region's highest high tide events.

The researchers used a suite of climate models to show that the link between ocean temperatures and rainfall only develops as a result of human influences on the climate system, such as greenhouse gas emissions and industrial pollution.

"We know that humans are continuing to make North Atlantic waters warmer, so we expect an increase in late summer rainfall in Florida in the future," said Jeremy Klavans, a PhD student at the UM Rosenstiel School and lead author of the study.
