Looks like the only thing that can save our sorry bunch!!

Hard to believe the Aussies have lost 5 or 6 world class players and
yet they can still outclass England in their own back yard.
Hope we don't lose 5-0 that would be a grim Summer!
Let's hope we get some heavy showers in Cardifff soon as the sorry bunch
who call themselves the England cricket team are struggling on a flat
pitch at 55 for 4

long axis typical of anomaly patterns that have been responsible for
prolonged cold westerlies.

As to GW being responsible for this pattern, I don't see why. The only
reason GW could cause something like this is if the NAD weakened
significantly or shut down altogether. The SST anomalies would then evolve
into a pattern similar to what I described above, only much more severe,
with a strong cold pool extending from Newfoundland to the UK. This would
lead to strong, cold, cyclonic westerlies over the UK but with low
rainfall
because of the low SST.


Why is the 564DAM line persistently a bit further north than it should be
then?
Or is it? GW could easily be responsible, if the Tropics are warming then
warmer, moister air is going to end up further north, is it not?

Sorry, I agree that the 564 line being further north - and all the others
too - is down to GW but not that the 564 line being further north is
responsible for the jet being further south. I think that reduced N-S
temperature contrast, because of the increase Arctic warming relative to the
tropics would lead to weaker jets and, presumably, they'd be further north.

Certainly, warmer, moister air due to GW will lead to heavier outbreaks of
rain when they occur. Deeper troposphere will also, I would have thought,
lead to more violent storms. How often we get these is something I wouldn't
like to guess - I'll leave it to the climate models.

I've lost interest. You cannot watch it nowadays anyway unless you have
access to Sky :-(
In 2005 it was brilliant, uniting the country, now it is all about money -
pathetic.

I'm not a massive cricket fan, though I enjoy a good Test Match.
You're right about 2005, people who had hitherto only had a
passing interest in the game suddenly found themselves hooked.
I recall more than once hurrying home from work to watch it!

Now of course, I can't do that.
The moneymen have seen to that.

Admittedly, I can't say where the 564 DAM line normally is this time of
year, but looking at the charts I don't see it being particularly far north.

and in the middle of the Atlantic it seem quite far south. Certainly
it's close to us on the near Continent, but am I missing something here?

In case there is anyone else, like me, who does not understand the
significance of the 564 DAM, I found the following on the Met Office
web site:

Thickness lines
Pressure decreases with altitude, and thickness measures the
difference in height between two standard pressure levels in the
atmosphere. It is proportional to the mean temperature of this layer
of air, so is a useful way of describing the temperature of an
airmass.

Weather charts commonly show contour lines of 1,000-500 hPa thickness,
which represent the depth (in decametres, where 1 dam = 10 m) of the
layer between the 1,000 hPa and 500 hPa pressure levels. Cold, polar
air has low thickness, and values of 528 dam or less frequently bring
snow to the UK. Conversely, warm, tropical air has high thickness, and
values in excess of 564 dam across the UK often indicate a heatwave.

Graham,

What you are saying makes more sense to me. The cold pool of surface
water in the North Atlantic seems to be flowing out from Baffin Bay.
My idea is that it is melting Arctic sea ice and/or melting ice bergs
from a fast retreating Greenland ice sheet. Melting ice would explain
why the cold water remains on the surface rather than sinking. It is
fresh water and so does not the higher density of saline sea water.
OTOH why don't we see it coming down from the east of Greenland.

I suspect that the features we see in Western Europe at present and
blame on global warming are caused by the melting Arctic sea ice. When
that is completely melted, there will be a new regime much like that
dreamed of by Will.

Cheers, Alastair.

Cheers, Alastair.

I'm with you on that. Nothing of mine will ever land up in

I'm not mad about sport, except possibly football and therefore a
certain club. Don't ask.
