Abstract: Linear and nonlinear behaviors of Venus?s planetary-scale waves are examined by using the two-dimensional model in the equatorial longitude?height plane. The zonal wave 1 gravity waves with phase velocities of 79 and 131 ...

Abstract: The Venus 4-day circulation, with wind speeds 60 times greater than the surface rotation, is located at the top of the cloud layer (65?70 km) in the middle atmosphere of the planet. This dramatic phenomenon is related to ...

Abstract: Venusian Y-shaped clouds have been observed by ultraviolet (UV) detectors. Recently, it has been demonstrated that the Y-shaped cloud pattern is maintained by the dynamical combination of an equatorial 4-day wave and a ...

Abstract: Fully developed superrotation?60 times faster than the planetary rotation (243 days)?is simulated using a Venus-like atmospheric general circulation model (AGCM). The angular momentum of the superrotation is pumped up by ...

Abstract: The present study examines the influence of an assimilation SST product on simulated monthly precipitation. The high-resolution SST structures located close to the oceanic front and coastal areas are important in regional ...

Abstract: Formation and maintenance of the fully developed superrotation in the Venus atmosphere are investigated by using a Center for Climate System Research/National Institute for Environmental Study (CCSR/NIES) Venus-like ...
