Has anyone else noticed these long strange periods of the wind not being in the prevailing direction?
We notice fairly quickly because we stop getting planes over our house in Clapton: normally they're coming in to land at Heathrow and taking off from City, but when the wind is 'backwards' City planes take off over the estuary and come in over south/central London to land and Heathrow flights taking off turn before they reach us. Weirdly though you can hear takeoffs from City carried by the wind, even though it's about five miles away - as well as the A12 of course - although the weaker the wind the less we hear them.
It was like this for ages earlier in the month, briefly went back to normal then yesterday reversed again.
Every day for the last three weeks has been headwind all the way home, consistently (and annoyingly), riding roughly SE. I thought it was something to do with jet streams?

What does it all mean? Global warming?
