A great deal of cloud physics is wrapped up in this printable chart.
The mastery of the chart will give you deep insight about the formation of particular types of clouds.
Clouds appear in a variety of pure and transitional forms. This chart gives a "grapenuts", concentrated, description of the factors that determine which of the l2 major cloud forms will be present at a given moment under a given set of circumstances.
A particular cloud is determined by the stability of the airmass in which it appears, the amount of positive (upward) buoyancy , or negative, in the airmass, the water vapor content, the temperature range, the presence of uplift due to fronts (cold, warm, occluded) and physical barriers (hills and mountains).
The information below the chart clarifies the meanings of the symbols e.g. under airmass stability uuu means very unstable, uu means somewhat unstable, etc.; under buoyancy +++ means very buoyant, ++ means somewhat buoyant, etc.
(You can print this chart, however it will be broken in half. A printable version is coming soon.)
