Rainfall associated with landfalling tropical cyclones plays a crucial role in terms of rainfall extremes and climatology in many areas of the world, from the tropics to the mid-latitudes. The flooding caused by these storms have been responsible for significant societal and economic impacts, with hundreds of fatalities and losses in the billions of dollars. In the United States alone, Hurricanes Harvey, Irma, and Maria (2017) and Hurricanes Florence and Michael (2018) represent some of the latest examples of the devastation associated with these storms. Therefore, an improved understanding and prediction of the heavy rainfall and flooding associated with tropical cyclones can provide basic information towards improving our preparedness, mitigation and management of these hazards.
