[4] A foehn wall cloud may exist at the lee side of the mountains, however this is not a reliable indication of the presence of lee waves. A pileus or cap cloud, similar to a lenticular cloud, may form above the mountain or cumulus cloud generating the wave.
The peculiar cigar-shaped cloud is called an altocumulus standing lenticular cloud (ASLC) and is created when winds encounter a steep barrier such as a mountain range, Nasa explained in a statement.
