And i suppose the irony is that on an exceptionally windy day here, do you see less in the way of craft out at sea and less people visiting the area, so a quieter day for you? when it's — the weather is like today, when it is quite breezy, you get less boats out. it's not so pleasant. we all do it for pleasure, boating, so conditions play a big part of that as well. how windy is it out there today? at the moment, it is blowing a force 6, which is approximately in the mid—20 knots range, so it is quite breezy. thank you, simon. well it's nice and warm and cosy inside here, but nick is outsi...

In the way of craft out at sea and less people visiting the area, so a quieter day for you? when it's — the weather is like today, when it is quite breezy, you get less boats out. it's not so pleasant. we all do it for pleasure, boating, so conditions play a big part of that as well. how windy is it out there today? at the moment, it is blowing a force 6, which is approximately in the mid—20 knots range, so it is quite breezy. thank you, simon. well it's nice and warm and cosy inside here, but nick is outside finding out just how it feels with that wind chill in a force six. well, sarah, i...

And this is a cup anemometer. in fact, it's the same technology as at that weather station at the old battery down there. the wind blows into the cup, spins it around on the spindle, and from that, you get just how windy it is. now, it's windier the higher up you go in the atmosphere, there's less friction to slow the air down — that is what the land surface does — so, actually, the uk's strongest wind gust was on cairngorms summit, of 173 miles an hour. a cup anemometer like this will probably get blown to pieces with a wind that strong, so you can have a sonic anemometer, which uses the ...

Metres above sea level. that wind is coming straight from the english channel, whizzing up the headland and then across and down, funnelling down into the solent and across the rest of the island. and this is what annette is talking about — a south—westerly wind has an unbroken path over hundreds of miles of open water, over which it blows towards the needles. then, when the wind hits the cliff underneath the weather station, it accelerates upwards and over it on to the anemometer, producing unusually high gusts. so, here, we've really got hundreds of miles, then, of unobstructed wind flow...

Now, it's windier the higher up you go in the atmosphere, there's less friction to slow the air down — that is what the land surface does — so, actually, the uk's strongest wind gust was on cairngorms summit, of 173 miles an hour. a cup anemometer like this will probably get blown to pieces with a wind that strong, so you can have a sonic anemometer, which uses the speed of sound waves to judge just how windy it is and from what direction. as clearly windy as it is here today, it's incredible to think the winds can be gusting over 100 miles an hour right here. a break from the wind now wit...
