The planetary missions including the Venus Climate Orbiter ‘Akatsuki’ provide new information on various atmospheric phenomena. Nevertheless, it is difficult to elucidate their three-dimensional structures globally and continuously only ...
<jats:p>At the cloud top of the Venus atmosphere, equatorial Kelvin waves have been observed and are considered to play an important role in the super-rotation. We were able to reproduce the wave in a general circulation model (GCM) by conducting ...
We examine the role of the filaments on the axisymmetrization of an isolated elliptic vortex with non-uniform vorticity distribution for a two-dimensional incompressible barotropic fluid, numerically. In order to perform quantitative examination o...
Evolution of an isolated 2-D elliptic vortex with non-uniform vorticity distribution is investigated from the viewpoint of the palinstrophy generation. As pointed out in a previous study, the palinstrophy generation rate has a quadrapole structure...
