However, the cloud sheet is not completely uniform, so that separate cloud bases still can be seen. This is the main precipitating type, however any rain is usually light. If the cloud layer becomes grayer to the point when individual clouds cannot be distinguished, stratocumulus turn into stratus clouds.
Stratus clouds do not produce accessory clouds, but a supplementary feature praecipitatio is derived from Latin, which means "precipitation". Stratus clouds are generally too low to produce virga, or rain shears that evaporate before reaching the ground, although higher stratus clouds can produce it.
Volutus clouds are much more common in the form of stratocumulus, as opposed to altocumulus volutus. [4] Stratocumulus volutus clouds are not severe, and may only bring several minutes of rain. [5] Alternatively, stratocumulus volutus clouds may form with numerous layers, contradicting the usual rounded form. [6]
If air near the surface becomes extremely warm and unstable, its upward motion can become quite explosive, resulting in towering cumulonimbiform clouds that can cause severe weather. As tiny water particles that make up the cloud group together to form droplets of rain, they are pulled down to earth by the force of gravity.
At level with stratus nebulosus translucidus (V-90) and opacus (V-91) clouds Stratus fractus (V-89) cloud. Abbreviation: St [9] Clouds of the genus stratus form in low horizontal layers having a ragged or uniform base. Ragged stratus often forms in precipitation while more uniform stratus forms in maritime or other moist stable air mass conditions.
Clouds and potentially fog can form within a marine layer when the water-saturated air is cooled and reaches a humidity of 100%, where it will then condense and turn into water droplets. [3] Stratus and stratocumulus can form at the top of a marine layer in the presence of these conditions. A marine layer can often be dispersed by sufficiently ...

Several factors influence cloud formation, including atmospheric temperature, humidity, and the presence of aerosols. Cloud types are classified based on their appearance and altitude, with major categories including cirrus, cumulus, and stratus. Understanding these processes is fundamental to studying weather patterns and climate dynamics.
