The impacts of tropical cyclones can be devastating, particularly from high winds and flooding due to heavy rainfall. Many developing nations with dense populations are particularly vulnerable and face high fatality rates and immense socioeconomic losses. Understanding trends in tropical cyclone related impacts, particularly for landfalling tropical cyclones regionally and globally, can help to better prepare these communities during such events, and provide a stronger foundation for studying climate related tropical cyclone trends.

Here, an analysis of the spatial characteristics of 21 years of tropical cyclone landfalling events sourced from the International Best Track Archive for Climate Stewardship from 1998-2018 on scales ranging from global to regional is presented. Using the NASA TRMM and GPM-based 3B42 and IMERG rainfall datasets along with DAV-based and Cross-Calibrated Multi-Platform wind fields from Remote Sensing Systems, the spatial and temporal characteristics of TC impacts are analyzed and mapped globally and regionally.  The trends in tropical cyclone impacts over the 21 years of the study will be discussed.
