As we are just about to have thunderstorms in the UK I thought I would start a discussion about the weather. What I really don't like is the forecasting system says it is very accurate but keeps getting it wrong, as I write we are supposed to be having heavy rain but it is dry as a bone.

  • I've been learning the gentle art, they've now got the world pretty much covered to about 5 days forwards. It starts with the various jet streams pushing things around, and the areas where the sea can't buffer if. At the moment, that's Central Africa along the equator, pumping energy across Panama onto the Pacific, although some drags around an Atlantic high, picking up more from the US. That was the case when this started mid-month, it was actually the remains of Tropical Storm Elsa, which flooded New York out, caught by the jet stream. Right now we're getting output from the US heat dome, picking up from the Gulf Stream. Sites like TropicalTitbits and WeatherNerds have the satellite shots showing the water content and wind, in terms of vorticity. It gathers at the coast until there's enough for standing winds like the Trades to grab, it then depends on water temperature c26°C to survive - 28 or 30, it'll grow, as long as no contrary winds rip it apart. We've seen a hurricane do exactly that last year, over a distance of maybe half a mile.
