A climatology of tropical cyclone eye sizes classified by “citizen scientists” through Cyclone Center, a website dedicated to the analysis of the Global Tropical Cyclone record of infrared satellite images, will be presented. Through this global analysis, a record of tropical cyclone eye size is determined from classifications of over 8,000 people for storms forming between 1978-2009. Images of tropical cyclones classified as “eye storms” are tabulated and placed into categories of eye sizes which form the basis of the climatology. Intensity estimates for individual tropical cyclone images are calculated through a process of synthesizing multiple weighted user classifications to form a consensus for the individual image. Tropical cyclone intensity estimates are then correlated to the specific categories of eye diameters in order to better distinguish the relationship between eye size and storm intensity.
