Altocumulus castellanus cumulogenitus clouds as seen from Floriana which developed over North Africa due to intense convection over the area because of strong heating. The first thumbnail is the weather sounding at the time that showed steep lapse rates at the upper levels of the atmosphere. Cloud formation may have been enhanced due to lots of dust in the atmosphere as per second image. It is well known that if atmospheric dust load is high enough, condensation could begin at a lower relative humidity hence forming clouds of water vapour mixed with dust that could also enhance lightning activity. The third thumnail shows a heat low that was present over North Africa whilst the fourth thumbnail is the unusually warm tongue representing the 25C line at 850mb height. The fifth image confirms the hazy atmosphere through actual visible satellite image. A blood rain shower with large drops occured from the photographed clouds.
