OROGRAPHIC EFFECTS ON FRONTAL CLOUD

by ZAMG and DHMZ


Common Remarks

Whilst passing a mountainous area a front can be modified by orography. Front delay is one possibility, decoupling of clouds at different heights is another. Two phenomena cannot be completely distinguished and are sometimes even difficult to detect because they occur in the same front.
Therefore, these two modifications will be treated as one CM in the Manual.
