The Cyclone Center algorithm, which relies heavily on the traditional Dvorak Enhanced Infrared (EIR) technique, has been recently enhanced by weighting individual classifiers through an Expectation Maximization (EM) algorithm. The EM technique is an iterative statistical process that weights user performance by comparing their classifications of scene type (e.g., eye storm, curved band, embedded center) to the most likely correct answer for a particular TC image. The classifications of users with the higher scores are then weighted more toward the final intensity estimate.
A presentation of the global tropical cyclone activity for 2005 - as determined by citizen scientists - will be made to highlight the performance of the enhanced Cyclone Center algorithm. The anticipated completion of the 32-year data set may provide a valuable resource for a global TC reanalysis.
