Abstract

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).

先进Dvorak技术(9.0)对北印度洋热带气旋的评价

先进德沃夏克技术(ADT)被世界各地的热带气旋预报中心用来从气象业务卫星上准确地评估热带气旋的强度。算法开发团队对目标ADT进行了新的改进，以进一步扩展其功能和准确性。因此，一项基于2018年、2019年和2020年所有北印度洋热带气旋(共15号)的研究对新版ADT(9.0)进行了评估。发现ADT(9.0)表现良好，符合IMD的最佳径迹T. No估计。ADT对T≥4.0 (VSCS至SCS)的强度估计较好，对T≤3.5(CS/SCS)的强度估计过高。

期刊介绍： Tropical Cyclone Research and Review is an international journal focusing on tropical cyclone monitoring, forecasting, and research as well as associated hydrological effects and disaster risk reduction. This journal is edited and published by the ESCAP/WMO Typhoon Committee (TC) and the Shanghai Typhoon Institute of the China Meteorology Administration (STI/CMA). Contributions from all tropical cyclone basins are welcome. Scope of the journal includes: • Reviews of tropical cyclones exhibiting unusual characteristics or behavior or resulting in disastrous impacts on Typhoon Committee Members and other regional WMO bodies • Advances in applied and basic tropical cyclone research or technology to improve tropical cyclone forecasts and warnings • Basic theoretical studies of tropical cyclones • Event reports, compelling images, and topic review reports of tropical cyclones • Impacts, risk assessments, and risk management techniques related to tropical cyclones
