Snowbound


From the MERIS satellite, the United Kingdom covered in snow. Travellers have been stuck at Heathrow airport up to two days, many sleeping on the floor. At St. Pancras station in London, terminus for the Eurostar, other travellers waited outside in the cold for hours. Some forecasts have the temperature sinking to -26C. These people need to pay more attention to Earth's climate.

The storm approaching California this week. Satellites are so invaluable for weather forecasting that today we take them for granted. Before spaceflight, weather forecasting was far more inexact than today. The billions saved due to weather satellites would probably pay for our entire Space program.

I would love to be there in the snow now, since I don't cope too well with the summer heat. Travelling long distances at this time of year is a nuisance at the best of times.

We had heavy snow near London at the end of November and last week. It's been removed from most of the roads now, but the pavements (sidewalks for Americans) are more icy than ever.

Temperatures are well below freezing at night but slightly above freezing during the day, so the snow gets trampled down and turns a bit slushy and wet during the day, then is frozen to a slippery icy surface overnight.

No use for running unless you want a broken leg. I would swap for a hot climate! The reported cause of the extremely cold weather in England is a deflection of the jetstream (blowing from the gulf region) away from England due to a high pressure system in the Atlantic. This allows Siberian cold air masses to dominate. The same happened last year as well.

It's possible that the deflection of the jetstream by the high pressure system over the Atlantic is a permanent winter fixture, due to a slight warming of the Atlantic ocean. Maybe someone could get some tugs and tow a floating ice shelf into the middle of the Atlantic to keep it cool and prevent the problem.

For Kea: Your concern about Earth's climate is always appreciated. Thanks again for the posts.

Glad you are hilding out, nige. Your comments on "Flatness" were cool too. Might make a post out of that.
