英文摘要: Global climate models have been shown to simulate tropical cyclone-like behavior even at relatively coarse resolution, and recent higher resolution simulations more accurately capture the intensity, structure, and interannual variability. Even the highest resolution global models, however, continue to underestimate the intensity of the strongest tropical cyclones. The simulated cyclone intensity has been shown by many studies to be greatly influenced by the fluxes at the air-sea interface. A simple modification has been implemented in the GEOS-5 atmospheric general circulationmodel (AGCM) based on existing theory and laboratory experiments, which demonstrated that the ocean roughness does not increase with surface stress beyond some threshold. A series of strong tropical cyclone simulations were performed with the GEOS-5 AGCM to evaluate the impact of imposing a limit on ocean surface roughness at high wind speeds. The results demonstrated clear improvements in cyclone intensity and structure in the simulations with limited ocean roughness. © 2013. American Geophysical Union. All Rights Reserved.
