An Isolated Cumulonimbus with Pileus Cloud over Mount Slavnik (1028m a.s.l.) Beyond Sunset; Slovenska Čičarija, Istrian Coastal Karst, Primorska, Koper, Slovenija

01-september-2022: there is a need for a certain quiet although this photo still demonstrates how energy is abundantly present in the atmosphere even in inland areas and without solar ground overheating.

 

The cloudy veils called "Pileus", that envelop this cumulonimbus cloud in full phase of development, are (basically) orographic lenticular clouds, where the Cumulus, of which they are accessory clouds, represents a sort of mountain which with its ascent generates, around itself, condensation and solidification of water vapor into these horizontal clouds (made up of ice crystals), a bit like what happens around real mountains when humidity increases and temperatures decrease.
