Good Morning Hong Kong….
Cirrocumulus clouds was seen over Tai Mo Shan. The above photo was taken at 06:23 a.m. on 30 October 2008.
Tai Mo Shan (大帽山) literally meaning “Big Hat Mountain” has the highest peak in Hong Kong, with an altitude of 958 m. It is located approximately at the geographical centre of the New Territories.
Cirrocumulus clouds (卷積雲) are high-altitude cloud, usually occurring at 16,000-40,000 feet. Like other cumulus clouds, cirrocumulus clouds signify convection. Unlike other cirrus clouds, cirrocumulus include liquid water droplets, although these are in a supercooled state. Ice crystals are also present, and typically, the ice crystals cause the supercooled water drops in the cloud to rapidly freeze, transforming the cirrocumulus into cirrostratus. This process can also produce precipitation in the form of a virga consisting of ice or snow. Thus cirrocumulus clouds are usually short-lived.
