Cc floccus

Cirrocumulus with rounded heads like very small pebbles or tufts of cotton in the sky hence the sub-species floccus although the whole cirrocumulus cloud itself might have been composed of varied subspecies. Such cloud always develops at an altitude of above 5km but well below 11km. In fact, the weather sounding of the first thumbnail indicated high-level clouds at an altitude of between 5.8km and 10km which is the ideal zone for this specific cloud formation along with the required instability at that height. In our case, due to an overall unstable atmosphere because of a broad high pressure system (2nd thumbnail) bringing very light and relatively cool wind over the Maltese Islands contrasting with a warmer sea surface temperature, had caused very isolated rain showers to form later in parts of Malta holding true the case that they are a precursor of bad weather because the atmospheric conditions that normally form these clouds could lead to bad weather. The photographed cloud may have originated from a convective thunderstorm over Tunisia which remnants were swept eastwards by the prevailing upper-level wind. This storm is indicated on the third thumbnail. Further clouds that developed on the same day could be viewed by clicking here.
