  In this work we study in a general view slow rotating planets as Venus or
Titan which present superrotating winds in their atmospheres. We are interested
in understanding what mechanisms are candidates to be sources of net angular
momentum to generate this kind of dynamics.
  In particular, in the case of Venus, in its atmosphere around an altitude of
100 Km relative to the surface, there exists winds that perform a full rotation
around the planet in four terrestrial days, whereas the venusian day is
equivalent to 243 terrestrial ones. This phenomenon called superrotation is
known since many decades. However, its origin and behaviour is not completely
understood. In this article we analise and ponderate the importance of
different effects to generate this dynamics.
