Activity of the volcano continues: a new viscous lava flow effuses at the lava dome. Ash explosions > 10 km (> 32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft. Seismic activity of the volcano decreased: only three explosive events occurred from 02:15 till 15:46 UTC on September 11

If you want to see images of the volcano before the eruption, including closeups of the dome, check out the KVERT page for Shiveluch.

“All memorable Dutch winters happened when the Atlantic was in a cold phase.
Nothing more nothing less.”

There is no relation. I have said what I’ve said. You may come with sources giving evidence to your hypothesis! I checked e.g. the record cold of 2 March 2005 and found the Atlantic in a warm fase.

“Any “hobby” meteorologist can tell you not to expect a cold August when the North Sea has warmed up to 20 degrees Celsius.”

After July 2006 the North Sea was record warm at 20-22° C. The ensuing August was decidely cool (also record wet). The North Sea does nothing to the jet.
By the way, there is no relation between a warm North Sea and rainfall in September/fall. Checked last week.

“Expect to have a winter similar to last year.
In other words, keep you skates at hand.”

It is well known that season prediction doesn’t work. Best we can say is: the chance winter 2009-10 will be warmer than the 1971-2000 average is near 5/6.

Hi Ron, as Jeroen explained above cold winter weather in Holland derives from blockings over the region Greenland-Scandinavia-Northwest Russia and these are associated with negative NAO. Blockings are relatively rare, but negative temp anomalies are large then. A winter sporting only four weeks of this generally ends up at the coldest in the record.
So yes, there is a definite link, which is well known in the met community here.

But it is hard to correlate the NAO with the distribution of cold and warm SST-pools in the Atlantic. We would have expected a cool to normal August based on the distribution this summer, but the month went into the top 10-percentile.

We all love ya! But long lines of plutonic activity are for nerds. Meet me at Nepenthe’s in Big Sur next weekend and I’ll show you some lines of unplatonic activity. ;-)

“Your link unfortunately does not work.”

Strange. Works for me. Shows global temperature anomaly for summer (JJA) 2009 and shows the US as on of three cool islands on a very warm globe.

“For colder weather conditions in the Netherlands you have to wait until the Atlantic cools down a little more but that’s only a matter of time.”

Wouldn’t help, as there is no discernible relation between cool pools in the Atlantic and winter weather in Holland. By the way, which part of the Atlantic do you mean?

RR Kampen,
I don’t know why the link does not work.

In regard to the winters in the Netherlands,
Have a look at this graph and tell me there is no link between the negative phases of the NOA and Dutch winters.
