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
