The deviation angle variance (DAV) method is an objective tool for estimating the intensity of
tropical cyclones (TCs) using geostationary infrared (IR) brightness temperature data. At
early stages in TC development, the DAV signal can be also a robust predictor of tropical
cyclogenesis. However, one of the problems with using the DAV method at these early
stages is that the operator has to subjectively track potentially developing cloud systems,
sometimes before they are clearly identifiable. Here, we present a method that allows us to …
