Clouds and Precipitation
![Page 2: Clouds and Precipitation. Cloud Naming Prefix indicates height – Cirro high, 5-13 km – Alto middle, 2-5 km – (none) low, 0-2 km Name for appearance.](https://reader036.fdocuments.net/reader036/viewer/2022062518/56649d2c5503460f94a023a9/html5/thumbnails/2.jpg)
Cloud Naming
• Prefix indicates height– Cirro high, 5-13 km– Alto middle, 2-5 km– (none) low, 0-2 km
• Name for appearance– Cirrus wispy strands– Stratus layered,
uniform– Cumulus puffy with
vertical structure
Nimbo/nimbus indicates significant precipitation potentialAdditional adjectives are used (table 7.3, p. 189)
