Describing two-dimensional vortical flows : the typhoon case
  We present results of a numerical study of the differential equation governing the stationary states of the two-dimensional planetary atmosphere and magnetized plasma (within the Charney Hasegawa Mima model). The most strinking result is that the equation appears to be able to reproduce the main features of the flow structure of a typhoon.
