Another NH Low Near 930 MB Within 2 Weeks

[bluewave]

We just saw a very deep low in the Pacific last week strengthen rapidly down to near 930 mb.

The Euro is hinting that we may see another low bomb out across the North Atlantic

later this week potentially down to near 930 mb or possibly lower. The -500 meter

or greater height anomaly is a signal that a very intense storm will develop there.

 

 

 

 

I am not sure how frequently we see a low near 930 mb or below in both the Pacific

and the Atlantic within two weeks in January. Any low in the North Atlantic under

930 mb mb  is noteworthy as the record is 914 mb back in January 1993.

The GFS is dropping the pressure down to 920 hpa.

 

Here is another shot of the Pacific beauty I took when it was approaching our far western Aleutians zones:

 

What was particularly impressive about the N Pac bomb was the latitude it formed at.

Nice one!  Since you mention it, here's the GFS:

Now that might be worthy of a name.

[baroclinic_instability]

ECMWF is progging some 60 hpa central pressure drop in 24 hours. That is getting up there with some of the greatest deepening rates of all-time in terms of pure central pressure drop without taking into account latitude variations (bergerons).

Yeah, it has the pressure this run falling down into the 920's  with a -569 meter anomaly at 500 mb.

Very warm SSTA in the NATL probably contributing to the strong intensity

Yeah, anytime a low reaches such intensity much of the energy is latent via incredibly warm/moist oceans. 12z GFS, once again, bottoming the low out to impressive low 920 levels.

[baroclinic_instability]

Surprised this event is not receiving more hype. We are nearing a record level N Atl low. Latest 00z GFS bottoms out the low sub 920 hpa again with near 65 hpa 24 hr pressure falls. Pretty incredible stuff should this even remotely verify, which, given the upper air setup and the current observational network the upper low/jet max is sitting over, is likely going to verify close to the latest modeling. Whether it hits near record levels remains to be seen, but this is an impressive event.

What type of wind would you expect in a storm of that magnitude? I would assume a large area of low end hurricane force winds in the SW quadrant. Regardless that would be a prolific swell producer for Europe with potential record breaking surf heights in Ireland.

Actually, a there was a 944mb storm in the North Atlantic south of Iceland. 00z January 20th.

[thewxmann]

I believe there was a 929 mb storm in that area a few years back. Would be cool if this got lower.

[bluewave]

So far there are only two known North Atlantic extratropical lows to drop below 920 mb.

NORTHERN HEMISPHERE: There are apparently two contenders for the record lowest pressure established in the northern hemisphere. 1) Storm of January 10, 1993 deepened to a central pressure of 912-915 mb (26.93”-27.02”) between Iceland and Scotland near 62°N 15°W and, 2) Storm of December 15-16, 1986 deepened to at least 916 mb south-east of Greenland near 62°N 32°W. A ship in the vicinity actually made a measurement of 920.2 mb on December 15th while still some distance from the center of the storm. The British Meteorological Office assessed the central pressure of the storm at this time as being 916 mb (27.05”) but the West German meteorological service proposed a pressure possibly as low as 912-913 mb (see Stephen Burt article in Weather magazine Vol. 42 pp. 53-56, February 1987).

 

The strongest low since those storms may be March 8, 2003.

Intense North Atlantic Storm, March 6-9: Strong high pressure developed behind the departing hurricane-force low above, forcing two following storms on more northward and then northeastward tracks, with the second system becoming absorbed by a much more intense storm late on March 7. The period of most rapid development of this powerful storm is shown in Figure 4. This low emerged off the mid-Atlantic coast of the U.S. as a 1001-hPa low at 1800 UTC March 6 and is shown passing south of Newfoundland twelve hours later (first part of Figure 4), about to absorb the preceding storm system east of Newfoundland (970-hPa). In the twenty-four hour period ending at 1200 UTC March 8, the central pressure dropped a remarkable 55-hPa (1.62 inches), or more than 2-hPa per hour. The system is shown at maximum intensity at 1800 UTC March 8 (second part of Figure 4) with a pressure of 924-hPa (27.29 inches). A search for intense North Atlantic lows in prior issues of Mariners Weather Log done in September 2002 for research turned up a 916-hPa low near the Faeroe Islands on January 11, 1993 as apparently the last low that was deeper than this one (Reference 2).

Very good memory. That looks like the deepest recent storm in that area.

0z/24 GFS, 920mb:

I wonder if they have adequate records of these things in the southern ocean.

Down to 950mb at 00z

 

[Dark Energy]

at 6z, it is down to 939mb!!

[Eyewall2005]

Can someone post a few links on were to get 1KM images of this low. Been searching but no luck on close ups.

[Superstorm93]

Down to 930mb

 

 

[OKpowdah]

Any good POES resources for satellite shots of this thing?

From OPC:

 

As awesome as the 936 bomb was in the N Pac, this system is just so much more impressive from a pure cyclogenesis viewpoint. A much more classic look to such an intense system. ERICA field experiments would have had fun with this storm.

 

[baroclinic_instability]

The entire cyclone, all the way from the frontal/jet cloud bands associated with the WCB all the way to the back of the bent-back emerging head, equals the size of Europe.

 

 

[andyhb]

Gorgeous.

[Superstorm93]

Such a beautiful beast of a cyclone.

Nice satellite animation of the storm.
