Abstract: The 5-day wave has been detected in composite maps of geopotential height fields of European Centre for Medium-Range Weather Forecasts dataset for 7 years (1984?91, except 1985) and shows a characteristic northwest?southeast ...

Abstract: The composite analysis of the 10-day and 16-day waves, the observational counterparts of the second antisymmetric and symmetric rotational Hough mode with the zonal wavenumber 1, respectively, were performed as an extension ...

Abstract: The characteristics and formation mechanism of an anticyclonic vortex street of meso-? scale, which appeared near a cold front around the Ryukyu Islands, Japan, on 11 April 1995, were examined by an analysis of observational ...

Abstract: A polar low was observed over the Japan Sea on 21 January 1997. Part I of this paper focuses on the observational analyses by using all available observational data from surface meteorological stations, Geostationary ...

Abstract: The characteristics and development mechanism of four meso-?-scale polar mesocyclones (M?PCs), which appeared as a vortex train over the Japan Sea from 0000 to 1700 UTC on 11 February 1997, are studied by means of observational ...

Abstract: In the fall of 1994, the Beaufort and Arctic Storms Experiment (BASE) was held to collect information on the structure and evolution of mesoscale weather systems over the southern Beaufort Sea and the Mackenzie River delta ...
