Abstract

AbstractTo understand the impacts of global warming on tropical cyclones (TCs), we compared various TC properties and environmental conditions during the pre‐industrial period with those in a warm climate with quadrupled CO2 concentration using the Seoul National University Earth System Model Version 0 with a unified convection scheme (SEM0‐UNICON). TCs in warm climate are faster, stronger, and larger with more precipitation but are short‐lived and fewer than those in cold climate. Fewer TCs in warm climate are associated with the decreases in the climatological mean upward flow at 500 hPa (ω500) and the increase in saturation deficit at 600 hPa (δ600). In contrast, enhanced TC intensity is associated with the increases in sea surface temperature, upward ω500, column‐integrated water vapor, convective available potential energy, and horizontal moisture convergence below 700 hPa along TC tracks.
