Mean zonal wind has decreased markedly at 60N.



Merry Christmas everyone :-)



Will,

Your link shows the zonal wind. The stratwarm is shown he

But if it is going to bring us cold weather surely the stratwarm has to

happen at the right longitude. What is the longitude for the stratwarms that

have brought us cold? How can we tell where this stratwarm is happening?



Cheers, Alastair.

It's really not difficult to do the research guys. The last minor SSW event (around 13th Dec) produced precisely *no* discernible effect on the UK weather.........not quite what some on here predicted. A minor event is currently happening. They quite often do during the boreal winter. The forecast is for the zonal wind at 10hpa to *increase* and certainly not to decrease, or to reverse. Thus the chances of this event affecting the surface would be extremely remote. The Meto 6+ day forecast implies they think exactly the same as I do.

You can see the reversal caused by the SSW of mid-dec can easily be seen in the 10hpa winds.

It's not hard to do the research on thisand learn. We've had people inferring that every SSW at all magnitudes will affect the UK weather in some way. That's plain daft. There is no research that says that* and it's just the butterfly's wings and the Atlantic hurricane stuff yet again. Basically, just ignore them. They know not what they say. *))

*All I say is show us the research that shows that they do. It's not much to ask.
