Cumulus cloud. Sky filled with "fair-weather" cumulus clouds stretching as far as the horizon. "Fair-weather" cumulus are small clouds of no great vertical extent and associated with mild weather. Cumulus clouds have rounded tops and a "cotton wool" appearance. Their flat bases,as seen here,show a clear condensation level at the level at which the cloud forms. Cumulus may be formed at a frontal system boundary or as a result of thermal cell activity,with a low-altitude cloud base at between 300 and 1,000 metres (1,000 and 3,000 feet). The depth varies generally between 500 and 1,500 metres (1,500 feet and 5,000 feet) | |
