One of the things I forgot about living in London is how the sky is different. There are no stars at night. Just one or two of the brighter planets. And lots of planes. The planes also leave vapour trails, which criss cross the sky during the day.
According to the online Britannica:
“[vapour trails or contrails are] streamers of cloud sometimes observed behind an airplane flying in clear, cold, humid air. It forms upon condensation of the water vapour produced by the combustion of fuel in the airplane engines. When the ambient relative humidity is high, the resulting ice-crystal plume may last for several hours. The trail may be distorted by the winds, and sometimes it spreads outwards to form a layer of cirrus cloud. On rare occasions, when the air is nearly saturated with water vapour, air circulation at the wing tips of an airplane may cause sufficient pressure and temperature reductions to cause cloud streamers to form.”
Right. That should sort out those who need to know.
Either way, they’re beautiful.
In other news, although some people might be a bit rude about Twitter, it’s proved itself as a place for great romance today. Ashton Kutcher arranged to have his followers greet his wife Demi Moore with love tweets when she got up in the morning and logged on (she’s away on business). Over 3600 tweets in the first 7 minutes and they’ve been streaming in all day. A love wave indeed.
If you were on twitter, my love, I’d send you a love wave.
