Extremely low pressure brought down air traffic over northern Norway
The Barents Observer ^ | Feb 11 2020 | Atle Staalesen

Posted on 02/14/2020 8:05:07 PM PST by texas booster

Airline company Widerøe has in its almost 90 year history never experienced this kind of weather.

The past months have seen extraordinarily rough weather along the north Norwegian coast. Early this week came another extreme. The air pressure dropped to a level not seen in several decades.

According to the Norwegian meteorological institute, the air pressure across major parts of the region was below 940 hectopascal, a level that makes flying unsafe.

The Widerøe company that serves most of the regional routes put almost its whole aircraft fleet on the ground.

"Our smallest aircraft type Dash 100, 200 and 300 can not fly with pressure lower than 948 hectopascal,"

More than 2,000 passengers were affected by the weather conditions. Only on Tuesday afternoon did the pressure return to a level that allows aircraft to operate normally.

The low pressure also resulted in high waters levels along the Norwegian coast. In Tromsø, the north Norwegian town, the sea water was on Tuesday 354 cm higher than normal, the Meteorological Institute informs.

354 cm = 139.37 inches...

The water level was up by 11.614 feet?

Didn’t see that you two had addressed this already.

That didn’t sound right.

11.614 feet.

Hmmmmmm...

Great thread! Hectopascal indeed.

I suspect the low pressure screwed with automated instrumentation somehow, since fixed wing aircraft work just fine at the stated barometric pressure.

In the US planes take off and land at airports at and above 5000 ft every day. Check the air pressure at 5000 ft altitude...

Yes. “Polar Vortex” repackaged under a new name.

From https://www.newsinenglish.no/2020/02/10/record-high-sea-levels-predicted/:

Sea levels are due to rise by as much as a meter above tidal tables in Vestlandet and Møre og Romsdal, both along the outer coast and within the fjords. Stavanger may see as much as a two-meter rise while Måløy in Vestland County was told to brace for nearly three meters, breaking the record of 282 centimeters over normal in January 1993.

The extremely high tides are blamed on the full moon combined with high astronomical water levels and a severe low-pressure system.

“Our smallest aircraft type Dash 100, 200 and 300 can not fly with pressure lower than 948 hectopascal”

I’ve never heard that before. Is that due to engine performance? I assume these aircraft are turboprop.

There are few things in life that I would enjoy more than flying that tin can over mountains where winds shift every mile or so.

Or not flying ...

Translation of photo:

Then the water level peak is also reached in # Tromsø. At 15, 354 cm was measured. It is a bit away from the record of 386 cm from 2011, but within the criteria for orange hazard warning. The water reached well over some jetty edges where one usually goes dry-shod.

All I know is that it was pretty rough in the ICW heading south this winter.

“Our smallest aircraft type Dash 100, 200 and 300 can not fly with pressure lower than 948 hectopascal,”

The Millennium Falcon did the Kessel Run in less than 948 hectopascals.

Probably a takeoff and landing issue. Not enough lift at friction-limited speeds for takeoff. Too much speed required to have enough lift to slowly descend to land.

We had very high tides here in Maine on Tuesday and Wednesday, but very calm weather. The water came right up to the road on Ocean Avenue at one of its lowest point in Kennebunkport. I did not have need to be at the water in other low lying spots on the coast so I don’t know if they had the same issues.

Thanks for the mention.

I’m not familiar with those instruments, so your take on it is appreciated.

That star wars quote was always so stupid, but probably wowed the low-inf types.

The MF did the run in units of pressure???
