Tropical cyclones in a warming world - first results from the ICCP high-resolution CESM simulations

Tropical cyclones play an important role in the global water and energy cycles. To understand how their character changes in response to greenhouse warming, it is crucial to properly resolve their synoptic to mesoscale dynamics as well their interactions with the ocean. Here we present the first results from a series of present-day and future climate change simulations conducted with the fully-coupled high-resolution Community Earth System Model (HR-CESM). The model uses 25 km horizontal resolution in the atmosphere and 10 km in the ocean. We apply cyclone tracking algorithms to detect the tropical cyclone paths. This presentation will discuss how increasing greenhouse gas concentrations and the resulting changes in sea surface temperature, atmospheric stability, humidity and background circulation will influence genesis location, extreme winds, cyclone tracks, as well future landfall characteristics.
