Research Abstract |
We reported in a cover article of Nature (13 Mar. 2008) that the Gulf Stream causes a series of atmospheric responses, not limited to the atmospheric boundary layer, but penetrate to the free troposphere. Also, we found two different atmospheric modes, i.e., the shallow heating mode prominent in winter and the deep heating mode in summer. The difference of the summer and winter atmospheric responses is associated with the atmospheric stability between the two seasons. A long-term numerical integration of an Atmosphere-Ocean Coupled General Circulation model realistically reproduces major features of the recent satellite surface-wind observations. Furthermore, the first observational evidence of wave breaking, which is expected to cause low sea-surface temperatures, associated with ocean tide is obtained.
