Is the climate changing towards more extreme swings of the NAO?  It's an interesting question.  Let's collect data for a few centuries, and then I think we will have an answer.... 32840 what kind of extreme cyclone would it take to actually form a black hole?! To get the most extreme cyclones, you w...

32775 I think it would be extremely interesting if we ever found two planets that shared an atmosphere (or more likely) a planet and a moon that share an atmosphere and if both were habitable we could see the swapping of life back and forth! Is it even possible, even if we ignore how they could evo...

If that prediction holds, merging into a 915 hPa centre, it will be very close to the lowest pressure ever recorded or even estimated in the North Atlantic.

32828 The effect on color balance is something that could be solved in post process Yes, but not trivially, I think, since amplifying the suppressed colours wiil also bring back the light pollution.  I think some kind of masking is necessary. One can argue that if post processing is necessary, then...

"GFS model generates an obscenely strong "extratropical cyclone" over the North Atlantic down to 918 mb (equivalent to a Category 5 hurricane -- a tropical cousin)"

Qr Bbpost What is going on? 

The North Atlantic Oscillation is going on.  Low pressure near Iceland, high pressure near the Azores.  This makes an expressway of warm and humid air into northern Europe.

Oh boy, this paper turned out to be trash.

32788 Have heard it has been down to 944 hPa Officially, 942.7 hPa was the lowest recorded yesterday, not far from the all-time record in Norway (excluding off-shore measurements) of 938.5 hPa.  Combined with the full moon, and near minimum distance to the moon, the result was extremely high sea le...

32780 Is this Storm Ciara? Yes, but different name in different countries.  It's a very big weather system seriously affecting a huge area from the upper the 40's to lower 70's latitude. 32782 Yes a lot of planes, mostly the aircrafts to Widerøe has been grounded in Northern Norway earlier today du...

Extremely low pressure between Iceland and Norway. pr.gif Several meteorological stations in Norway will approach 940 hPa today, close to the all time low ever measured in Norway.  Even in Oslo I now measure 952 hPa, which is the lowest I've recorded and my record goes back 17 years.  This situation...

Wow.

32672 Isn't there some weird star out there which seems to show variations that haven't been explained by natural means?  I forget its name.... There are so many stars out there that there will also be some stars behaving in unusual ways. The universe is big and extremely rare events happen all the...

32657 I have already considered whether the decrease in the brightness of Betelgeuse could not have been caused by a kind of star-lifting. That sounds pretty ridiculous.  Even if you manage to focus the stellar mass quite a bit, it will still be a pretty thin soup to harvest.  Betelgeuse is practic...

Meteorite impact 2 billion years ago may have ended an ice age Well, perhaps.  I'm not too fond of such hypotheses.  A process that could take tens of million years, so no need for a catastrophic event that took place 2nd August 2,264,175 BCE, tea time, to explain it.  Also, there's no need for a s...

32605 I heard that snow has been making it down to sea level in Washington State! Whilst in Scandinavia there is hardly any snow at the sea level now.  You need to go north of the arctic circle for that.  Here in Oslo we had a decent amount of snow in November, but since Christmas the  NAO  has sen...
