Web[2] Superrotation is a feature of a number of planetary atmospheres, although the mechanisms that give rise to it may differ from case to case. It is a well‐known result that an axisymmetric atmosphere cannot superrotate if there is a diffusive mechanism that acts to mix angular momentum down gradient [Hide, 1969]. http://rsss.ece.illinois.edu/sites/rsss.ece.illinois.edu/files/Large%20Aperture%20LidarOptical%20Facility%20Workshop%20Description.pdf 10減10増WebJun 6, 2014 · Planetary superrotation commonly refers to atmospheric circulations with persistent zonal mean westerly winds over the equator.
