Weather Events

Since Lee Cloudiness develops in a stable stratified atmosphere and is characterised by clouds with generally small vertical extent, normally there is no convective activity nor precipitation.

Parameter Description
Precipitation
  • Hardly any precipitation due to stable stratification.
  • Superimposed over lower layered cloudiness slight rain or snow can observed (seeder feeder mechanism)
Temperature
  • No significant feature
Wind (incl. gusts)
  • No significant feature
Other relevant information
  • Moderate precipitation when lee clouds merge with frontal clouds.
  • Risk of high level turbulence in rotor flows near the mountain crests
