Wave Cloud

A terrific display of orographic lee wave cloud across NENE North East Scotland that extends eastward into Norway. Unusually, all the LCBR across northeast Scotland are reporting zilch in terms of medium or upper cloud heights this lunchtime, so I had to revert to some Weather Watcher images as a last resort.

These Weather Watcher pictures show the base of the lenticular ACAC Altocumulus clouds are generally associated with settled weather and will normally appear white or grey with shading. Height of base: 7,000 - 18,000 ft Shape: Bands or areas of individual cells Latin: altum - height; cumulus - heap Altocumulus clouds are small mid-level layers or patches of clouds, called cloudlets, which most commonly exist in the shape of rounded clumps. There are many varieties of altocumulus, however, meaning they can appear in a range of shapes. Altocumulus are made up of a mix of ice and water, giving them a slightly more ethereal appearance than the big and fluffy lower level cumulus./CICI Cloud, comprised of ice crystals that form wispy filamentous tufted streaks or ‘mare's tails’ at high altitude usually 16,500 to 45,000 ft./CSCS Ice cloud forming a thin, more or less uniform semi-translucent layer at high altitude, usually 16,500 to 45,000 ft. cloud is very high, maybe 18,000 ft or higher by the look of it.
