The Advanced Dvorak Technique (ADT) is used operationally by Tropical Cyclone Forecast Centers (TCFC) worldwide to help estimate the intensity of tropical cyclones (TCs) from satellites. New enhancements to the ADT are currently being explored and implemented by the development team at UWisc.-CIMSS to further expand the capabilities and precision of the objective algorithm. These advancements include 1) an upgraded algorithm to objectively estimate a storm center position, 2) adjustments to the intensity estimates during extratropical transition, 3) operability and tuning for improved use with subtropical cyclones, and 4) a 2D Wind Radii estimation routine. The goals of these upgrades are to provide TCFC analysts/forecasters with an expanded tool to more accurately estimate intensity for TCs, and those storms forming from, or converting into, hybrid/non-tropical systems. In addition, the algorithm developers will show the algorithm performance from the historic 2017 North Atlantic tropical cyclone season, including results obtained with GOES-16 imagery.
