摘要: Abstract Extratropical cyclones and how they may change in a warmer climate have been investigated detail with high-resolution version of the ECHAM5 global model. A spectral resolution T213 (63 km) is used for two 32-yr periods at end twentieth twenty-first centuries integrated Intergovernmental Panel on Climate Change (IPCC) A1B scenario. Extremes pressure, vorticity, wind, precipitation associated are compared lower-resolution simulation. Comparison observations extreme wind speeds indicates that model reproduces realistic values. This study also investigates ability to simulate extratropical by computing composites intense storms contrasting them same from 40-yr ECMWF Re-Analysis (ERA-40). Composites time evolution reproduced great fidelity; particular central surface pressure almost ex...
