[ACG52-P03] Detection and Analysis of Tropical Cyclones in the d4pdf Mega-ensemble Projection
Keywords:tropical cyclone tracks, d4PDF, climate ensemble, IBTrACS, JRA-55
Here, a tropical cyclone track dataset has been created for the d4PDF dataset. The detection method uses pressure difference, wind speed, and SST threshold parameters and is tuned to optimize annual TC count and cyclogenesis locations. Tuning and validation of the method is conducted using 30-year IBTrACS observation and JRA-55 reanalysis data. We will present an overview of the detection method, validation, and performance, and analyze properties of the TC tracks, such as projected changes in occurrence frequency, and cyclogenesis and dissipation locations.
