Tropical cyclones are among the most destructive meteorological phenomena on Earth. In a changing climate, researchers wish to understand how various aspects of tropical cyclones are changing. One aspect of tropical cyclones that has received recent attention is size. The purpose of this project is to explore the relationship between tropical cyclone size and insurance losses. To that end, a dataset of tropical cyclone size, specifically the radius of outermost closed isobar size parameter, is created with the retroactive analysis dataset NCEP/NCAR Reanalysis I. Insurance loss data was collected from the catastrophe insurance provider Icat. Exploratory analysis is conducted on both the size and insurance data, followed by investigations into the relationship between size and insurance on both global and regional scales.
