Does this actual case reflect the conceptual model well? Compare the ideal configuration!
Isotachs 300 hPa:
- Lee Cloud Alps:
There is jet streak in connection to the front west of the Alps; but there is no clear connection of the Lee Cloud to the anticyclonic side of the jet axis. - Lee Cloud Scandinavian mountains:
There is a double structure of jetstreaks and no clear connection to the anticyclonic side of the jet axis.
Wind Vectors 500 hPa:
- Lee Cloud Alps:
The wind vectors clearly show a perpendicular orientation to the mountain chain and the developed Lee Cloud. This is very typical for this conceptual model. - Lee Cloud Scandinavian mountains:
The wind vectors clearly show a perpendicular orientation to the mountain chain and the developed Lee Cloud. This is very typical for this conceptual model.
Showalter Index:
- Lee Cloud Alps:
In this case, there is an unstable area South of the Alps which seems to reach also the lee side of the mountain chain. The results of this instability can clearly be seen at the leading edge of the frontal cloud band south of the Alps in form of extended cloud cells. North of the Alps where the lee cloud has developed the unstable values deviate from the expected configuration. - Lee Cloud Scandinavian mountains:
Values of Showalter index show a stable situation which is typical for this kind of cloud.
