Man-made clouds
The only clouds in a clear cold sky today were contrails, the condensation trails left by aircraft exhaust gases turned to ice crystals at high altitudes. They're evidence of the pollution of our skies by aircraft. For three days after 9/11, all commercial flights over the US were grounded. The exhaust fumes containing water, carbon dioxide, oxides of sulphur and nitrogen, hydrocarbons, carbon monoxide, unburned fuel and particles of soot and metal were dispersed. The difference between daytime and night-time temperatures was greater than normal, showing that contrails, which can spread into sheets of persistent cirrus, have a warming blanket effect.

Still grey
Took this from the car on the way home on another murky afternoon.
The forecast for tomorrow is "sunny intervals".

Can't quite make up its mind
The weather, that is. At bedtime last night it was pitch dark outside but the stratus cleared overnight and I woke to a clear blue sky. Since then, a few cumulus humilis have been hanging around, waiting for their mates, and now they're all joining up and forming proper cumulus heaps.

A cumulus humilis sort of day
Clear blue sky this morning. A few scattered fair weather cumulus later on. Lots of people out walking in the Sunday sun.
Cumulus humilis, with raggedy edges, come and go in less than ten minutes, drifting about in a lackadaisical sort of way. The blurry bits underneath indicate some precipitation, but it quickly evaporates.

Cirrus
There were lots of trails and hooks in the sky a few days ago.
These clouds were named by Luke Howard, who thought they looked like a lock of child's hair. Cirrus is the Latin name for a curl.
