Clouds Formation

+ Species Cumulus fractus (Cu fra): Cumulus clouds broken up into ragged and changing fragments.
+ Species Cumulus humilis (Cu hum): Small cumulus clouds usually with just a light grey shading underneath.
+ Species Cumulus mediocris (Cu med): Cumulus clouds of moderate size with medium grey shading underneath. Cumulus mediocris can produce scattered showers of light intensity.
- Genus Nimbostratus (Ns): A diffuse dark grey non-convective layer that looks feebly illuminated from the inside. It normally forms from altostratus along warm fronts and around low pressure areas and produces widespread steady precipitation that can reach moderate or heavy intensity.
