摘要：The Advanced Dvorak Technique (ADT) is used by tropical cyclone prediction centres around the world to accurately evaluate the intensity of tropical cyclones (TCs) from meteorological operational satellites. The algorithm development team has introduced new improvements to the objective ADT to further extend its capabilities and accuracy. A study has therefore undergone to evaluate the new edition of ADT (9.0) based on all the North Indian Ocean Tropical cyclones during 2018, 2019 and 2020 (Total 15 No.). It is found that ADT (9.0) performed well with the conformity of IMD’s best track T. No estimates. ADT is reasonably good in estimating the intensity for T ≥ 4.0 (VSCS to SuCS) and overestimate the intensity for T ≤ 3.5(CS/SCS).
