Living in England, it is of course imperative to talk about the weather

Well, it rained in Sydney for the World Cup final, it is raining and the sky is grey here in London, and two cricket matches in Sri Lanka have been abandoned without play due to rain. Are these separate weather patterns, or is it one big patch of cloud and rain covering Europe, Asia, and Australia? (Yes, I do know the answer, and even that this speculation is silly, and in any event it is easy to check by looking at a satellite photograph or too. However, the weather is getting me down a little).
