Abstract: Global behavior of the 5- and 10-day waves, which are typical modes of normal mode Rossby waves, has been investigated for the region up to the mesopause with the aid of Upper Atmosphere Research Satellite Improved ...

Abstract: The influence of normal mode Rossby waves on the mean field is investigated with the aid of TIROS-N/NOAA satellite observations by applying the Eliassen-Palm (E-P) flux diagnostics. Despite the fact that the normal mode ...

Abstract: A global analysis is made of large-scale traveling planetary waves in the upper stratosphere by the use of stratospheric height and thickness data up to the 1 mb level derived from the Stratospheric Sounding Unit (SSU) on ...

Abstract: As an extension of our recent previous study, the global structure and behavior of higher-mode Rossby waves am investigated with the aid of TIROS-N and NOAA-A satellite observations for the period November 1979 through ...

Abstract: Predictability of a zonal-wavenumber (WN) 1 stratospheric sudden warming (SSW) event occurring in December 1998 is examined using the operational 1-month forecast dataset based upon a numerical weather prediction model ...

Abstract: Though normal mode Rossby waves frequently appear in the troposphere and the stratosphere, excitation mechanisms of normal mode Rossby waves are not clear. In this study, excitation mechanisms of the 5-day wave, which is ...

Abstract: The major stratospheric sudden warming (SSW) event of January 2009 is analyzed using the Japan Meteorological Agency (JMA) Climate Data Assimilation System (JCDAS). This SSW event is characterized by the extraordinary ...
