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.

Boring blue sky


























No clouds today - not one! I've included the sun and some vegetation in this photo, or it would be just a blue square.
The Cloud Appreciation Society's manifesto includes the words,
We pledge to fight ‘blue-sky thinking’ wherever we find it. Life would be dull if we had to look up at cloudless monotony day after day.
I'm hoping for some clouds tomorrow, even if only a few little ones. And some rain. It hasn't rained for days. The garden is parched.

Golden sunset

After a cooler day and an even cooler evening.

Wisps

A hot day with mostly clear skies, apart from a few cumulus humilis and even fewer wisps of cumulus fractus, like these, that evaporate within minutes.

Blended colours

Someone took an airbrush to the sky over the horizon at moonrise.

Cloudy ripples

Another hot day. At about 12:30 these neat cirrocumulus stratiformis were overhead, high in the atmosphere (between 5 to 14 km or 16,000 to 45,00 ft) where upward air currents meet high cirrostratus clouds formed of ice crystals, some of which turn into supercooled water droplets. Not long afterwards they'd disappeared, or almost disappeared; just a ghostly trace of a few in small transparent patches in an otherwise blue sky.

Hot and bright

A hot day, even at about 18:45, when these were taken. Streaks of cirrus show that there were high winds at high altitude, while clumps of cumulus mediocris and wisps of cumulus fractus moved more slowly.

Cool sunset

Looking south-east, reflected light on altocumulus bobbles, like fluff.
Sunset streaks at different levels - stratocumulus, altocumulus, cirrus and contrails.
A little later - blue, grey, and apricot.
