    This was a programme on BBC4 this week and it looked at how the jet stream was detected by USAF Stratocaster bombers over Japan starting a programme of discovery (or rather rediscovery as a Japanese scientist had observed the phenomena 20 years earlier but he wrote his report in Esperanto and it got overlooked!).

    Its impact on this part of the world was interesting - I did'nt realise the stream in the northern hemispehere starts over North Africa and weaves its way around the globe to us where it peters out in a flurry of storms. The most intriguing part suggested that the stream is pushing north bit by bit. The met-office in UK seems to belive the outlook will be warm/wet in winter and hot summers spiked with intense rainfall events thanks to the lack of jet stream. The possibility of a greater frequency of blocking highs in winter was considered unlikely so snow fiends can forgot anymore 1963 events.

    The programme is repeated Saturday night at 12:25 am

    Well if that's what you took from it the programme must have been flawed!

    There are 2 jetstreams in the Northern Hemisphere.

    The Subtropical Jetstream around 10N and the Polar Jetstream which moves along the polar front(40-60N), the polar jet is what affects our weather ;)

    Good programme, well thought out. Worth watching.
