Research Objectives Investigate the ability of GCMs to capture tropical storm activity in terms of location, frequency, intensity and structure, considering both model resolution and model formulation. Utilise our ability to run coupled AOGCMs for multi-century simulations to help us understand climate variability, and how this affects tropical cyclone activity Identify and extract storm tracks from these simulations to build a long-term, spatially consistent, database of dynamically simulated storms. Develop methodologies to combine the capabilities of observations and GCMs to create storm event-sets, to be used as tools to investigate the impact of long-term variability on climate- related hazards. 20 year timeslice of dynamically simulated storms Interannual variability: Atlantic tropical cyclone count Correlation with BestTrack: High res: 0.73 Mid res: 0.44 Low res: 0.13 North Atlantic annual tropical cyclone count 50 yrs observed 150 yrs simulated (HiGEM) Track density anomaly for El Nino/ La Nina storms El Nino La Nina
