- Cumuliform or Cumulus Clouds
- A thick cloud that is usually isolated with a dark horizontal base with upper parts that look like domes or towers and may produce thunderstorms. These clouds have short duration exposures to high liquid water contents of up to 2.5g/m3, or up to 6-8 g/m3 for large tropical cumulonimbus clouds. The horizontal extent averages from 2-6 nautical miles for a single cloud but may be greater in convective clound lines or cloud clusters. Icing in these clouds can be either glaze or rime but the higher liquid water contents makes glaze ice more prevelant.
