Abstract: On 17 September 2006, three tornadoes occurred along the east coast of Kyusyu Island in western Japan during the passage of an outer rainband in the right-front quadrant of Typhoon Shanshan. To clarify the structure of the ...

Abstract: A remarkable isolated polar low observed over the Japan Sea on 21 January 1997 is studied by numerical simulations using a 20-km-mesh regional primitive equation model [Regional Spectral Model (RSM) of the Japan Meteorological ...

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: A high-resolution version of the limited-area primitive equations model of the Bureau of Meteorology Research Centre is used to investigate the dynamics and prediction of the mesoscale, extreme rain event of 1 August 1993 ...

Abstract: The structure and formation mechanism of a supercell-like storm in a moist environment below a melting layer were investigated using dual-Doppler radar analysis and a cloud-resolving storm simulator (CReSS). The supercell-like ...

Abstract: The spectral boundary coupling (SBC) method, which is an approach used to couple a limited-area model with a large-scale model, was introduced into a nonhydrostatic model. To investigate whether the SBC method works well ...

Abstract: An operational nonhydrostatic mesoscale model has been developed by the Numerical Prediction Division (NPD) of the Japan Meteorological Agency (JMA) in partnership with the Meteorological Research Institute (MRI). The model ...
