Take a look at AIP Gen 3.5.10 pars 7.4

7.4 When there is no cloud below 5000 ft or below the highest minimum sector altitude (whichever is the greater) and there is no
towering cumulus or cumulonimbus, 'NSC' (no significant cloud) is reported. However, the amount, height of cloud base and cloud type
of towering cumulus or cumulonimbus shall be reported, irrespective of the cloud base height.

AIP Gen 3.5 is the best reference for Aviation Met meanings and definations.


Cheers***
