Automated tropical cyclone eye detection using discriminant analysis
MetadataShow full item record
Eye formation is often associated with rapid intensification of tropical cyclones, so this information is very valuable to hurricane forecasters. Linear and Quadratic Discriminant Analysis (LDA and QDA) were utilized to develop a method for objectively determining whether or not a tropical cyclone has an eye. The input to the algorithms included basic storm information that is routinely available to forecasters, including the maximum wind, latitude and longitude of the storm center, and the storm motion vector. Infrared imagery from geostationary satellites in a 320 km by 320 km region around ...
