CL = 8



Cumulus and Stratocumulus other than Stratocumulus cumulogenitus, with bases at different levels.


(i) The code figure CL = 8 applies when Cumulus clouds form beneath patches or a sheet or layer Stratocumulus non-cumulogenitus.

(ii) Cumulus may penetrate (enter or enter and pass through) the Stratocumulus.

(iii) Cumulus does not, however, spread out and form Stratocumulus cumulogenitus.

(iv) The code figure CL = 8 also applies when Cumulus are observed above Stratocumulus. An example is Altocumulus castellanus towers developing and transitioning into Cumulus mediocris or congestus.
