Cold clouds on a hot day
Altocumulus (lower left) and cirrocumulus (all the rest) on another hot day, 31° in the shade. Poor grocery delivery driver said it was 33° in his cab - no air conditioning.
Can't get my head around the fact that it's so hot down here, and heat rises, yet those cirrocumulus clouds will be at least 20,000 feet up, formed from ice crystals or super-cooled water.
