Impacts of Global Warming Events on Tropical Cyclones
Meng-Pai Hung, The Ohio State University, Columbus, OH; and J. Lin
This study investigates the variability of tropical cyclone (TC) activities in all ocean basins associated with the global warming events in the last 43 years (1966-2008). Most of the previous studies on TC-global warming relationship focused on the long-term trend, while our study focused on the shorter time-scale global warming events. The datasets used include TC data from the International Best Track Archive for Climate Stewardship (IBTrACS) and large-scale surface and atmospheric conditions from NCEP/NCAR Reanalysis. We found significant impacts of global warming events on TC activities in the Western North Pacific (WNP), in terms of the number of TC genesis, number of TC presence, mean accumulated cyclone energy (MACE), and total accumulated cyclone energy (TACE). Detailed results will be presented at the conference.
