Abstract

The Advanced Dvorak Technique (ADT) has been installed in India Meteorological Department experimentally since 2014. There is a need to validate this technique before it’s used operationally. Hence a study has undertaken to validate ADT (V8.1.3B) & ADT (V8.2.1) based on all the TCs (34 Knots & above) over the North Indian Ocean during 2014 & 2015 (total 7 no.). The performance of ADT has been compared with manual T number. It indicates that ADT (V8.2.1) overestimates by about 1 T number as compared to manual T number of 1.0 to 2.5 and underestimates by about 0.5 to 1 T number as compared to manual T number of 4.0 to 5.5. Further comparison with CIMSS ADT indicates that IMD ADT underestimates by about 1 T number compared to T number based on CIMSS ADT.
