The Jet Stream

[Medskipper]

The jet stream is being blamed for this apalling summer we are having. It has been said that it is too far south which has caused all this rain to be dumped on us rather than well north out at sea.

None of the weather men I have been listening to on the news seem to have an answer to this question, the question is will the jet stream move back north again in the near future? from the little that I know about this sort of thing I reckon it moves very slowly indeed, so the rest of this summer is likely to remain pretty wet!

Any real experts out there know any different?

Granted that the position of the jetstream determines our weather but what determines where the jetstream is? Why is it further south this year than last?

That would be March, when I was happily wearing shorts, which have been retired to winter wardrobe for the rest of the year.

Just got this info from the BBC website if anyone's interested, mind you its by Michael-what hurricane-Fish......

Most people cannot have failed to notice that the weather has been generally overcast and dull lately. But before everyone writes off summer and mumbles something about global warming, let me explain why.
High in the sky above the United Kingdom, in a layer of the Earth's atmosphere called the troposphere, wind speeds can reach 200mph.
This ribbon of high altitude high speed wind is known as the polar jet stream, and is responsible for steering weather in our direction.
To bring us the summer we are longing for, the jet stream needs to pass to the north of the UK.
This allows the Azores High, an area of high pressure situated in the mid-Atlantic, to bring us warm and settled weather.
This type of weather set-up allowed the temperature to reach 33 degrees Celsius (91 degrees Fahrenheit) in Cardiff on this day last year, and brought us the prolonged period of hot weather in August 2003.
Lately, however, the jet stream has not been playing ball.
It is currently passing straight over the top of the UK, and is steering low pressure systems our way that are responsible for the damp, windy weather we've had to put up with recently.
This week in Cardiff we expected the mercury to only reach about 19°C (66°F). But as depressing as it sounds, 19°C is just one degree below the average daily maximum for Cardiff in July.
Gloom
The polar jet stream naturally wavers around in the upper atmosphere and so it is not uncommon for it to be passing over our latitudes.
We are therefore not in a "freak" weather pattern, it's just average.
Our cause is not helped by the fact that we Brits appear to have short memories.
Think back far enough and you may recall that most of the UK had beautifully settled weather for much of May and the first half of June.
Since then summer has taken a holiday.
Northern Europe is suffering the gloom the same as us.
So when will it be back? Well, there is no immediate return to summer as this weekend promises more rain or showers for most.
The Met Office seasonal forecast perhaps can offer a little glimmer of hope however - "through the middle of the month as the Azores high extends gradually towards the UK, the weather will become more settled, with temperatures gradually rising."
So don't pack away the sun lotion and beach towels just yet.

Experts are only good at explaining ex-post why these things happened.
'Long-term forecasts' should rather be called gambles.

Well I did notice that April was nice, but May and June? perhaps I was too busy working!

Still on the bright side its good to know that all the crap we have been having is NORMAL!! little wonder Spain and the Med areas have become so rich!
