11. Free convective clouds generally form at the altitude of the convective condensation level ( CCL ). 12. Convective rain, or showery precipitation, occurs from convective clouds , e . g ., cumulonimbus or cumulus congestus. 13. Central Argentina, which includes the Pampas to the east, and the convective cloud tops, in the world. 14. The largest free-convective clouds comprise the genus cumulonimbus which are multi-�tage because of their towering vertical extent. 15. Pyrocumulus ( No official abbreviation ) is a free convective cloud associated with volcanic eruptions and large-scale fires. 16. Convective precipitation falls over a certain area for a relatively short time, as convective clouds have limited horizontal extent. 17. Convective rain, or showery precipitation, occurs from convective clouds ( e . g ., cumulonimbus or cumulus congestus ). 18. Moderate turbulence will typically transform a fog bank, lifting it and breaking it up into shallow convective clouds called stratocumulus. 19. Moreover, the International Cloud Atlas ( ICA ) is not entirely precise regarding how to determine the genus of a convective cloud . 20. If the airmass has one or many LFC, it is potentially unstable and may lead to convective clouds like cumulus and thunderstorms.
