The Convergence Cloudiness CM represents a quasi-frontal situation, in effect, attached to the end of an Occlusion. Therefore weather events are frontal in character.

  • Convective features are unlikely.

Wind (incl. gusts)
  • Surface winds weak at the transition zone where the cloudiness joins the Occlusion
