Weather Events

A Deformation Band occurs when there is deformation of the cloudiness at middle or upper levels in the troposphere. There are no weather events at the surface associated with a Deformation Band. The example below shows a Deformation Band over Western Europe.

Parameter Description
Precipitation
  • No precipitation associated with Deformation Band. Existing rainbands tend to weaken at deformation areas.
  • Precipitation from low level clouds not dependent on deformation at upper levels
Temperature
  • No significant change
Wind (incl. gusts)
  • No significant change
Other relevant information
  • Upper/middle level cloudiness dispersing
  • High level cloudiness in the form of fibres
