Description
Summary:A satellite multi-sensor approach is being evaluated to extract improved estimates of tropical cyclone intensity and storm structure. Forecast centers have operationally relied on intensity estimates derived from the Dvorak method (Dvorak, 1984) applied to visible and infrared imagery. This methodology has several shortcomings inherent with this type of imagery, such as when multiple cloud decks obscure the features required for accurate classification. Problems also arise when dealing with storms that. rapidly change intensity, storms spun off of monsoon depressions, and midget typhoons.
