Weather Events

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.

Parameter Description
Precipitation
  • Widespread precipitation in the form of rain or snowfall, in some cases it can be more than from Occlusion cloudiness.
  • Convective features are unlikely.
Temperature
  • Rises weakly after Convergence Cloudiness
Wind (incl. gusts)
  • Surface winds weak at the transition zone where the cloudiness joins the Occlusion
Other relevant information None
