| Term | Definition |
|---|---|
| Cumulus | Often called “fair-weather” clouds, cumulus clouds are common over land on sunny days, when the sun heats the land creating thermal convection currents |
| Cumulonimbus | Tropospheric winds need to increase considerably with height to encourage it to slant forward |
| Stratus | are formed when a large air mass cools at the same time (e.g. – a warm air parcel drifts into or above a cooler region) |
| Stratocumulus | Similar to cumulus clouds in form and composition, stratocumulus clouds are textured and puffy, but also joined into a semi-continuous layer |
| Altocumulus | are high in the sky, they are generally above the influence of thermals, |
| Altostratus | are potentially dangerous to aircraft because they can cause ice accumulation on the wings. |
| Nimbostratus | has no species or varieties. It is a thick, wet blanket with a ragged base caused by the continual precipitation |
| Cirrus | are the highest of all clouds and are composed entirely of ice crystals |
| Cirrocumulus | are usually a transitional phase between cirrus and cirrostratus clouds. |
| Cirrostratus | clouds are difficult to spot and appear as a pale, milky lightening of the sky. |
