Re: NE of Azores Islands : INVEST 92L
It's funny this invest has looked better than some of the tropical storms last year like Arthur and Nana.

for me it's an evident tropical storm like others insolit north Atlantic Hurricane over cold water and derived from exstratropical cyclone or cut off (Vince,Karl,ecc.)

Re: NE of Azores Islands : INVEST 92L
It sure looks cold core to me. Shallow convection, possibility of frontogenesis on the SE quadrant, cold anomaly. (The warm anomaly aloft is the result of tropopause suppression and stratospheric air getting into the cross section...it is north of 40N after all).

Re: NE of Azores Islands : INVEST 92L
Reanalysis? 92L was never a TC. Sure it looked great from space but it was cold core all the way.....MGC

I don't expect it to be upgraded to TC on reanalysis but maybe to a Subtropical Cyclone.

92L it's a Tropical storm for me, with warm core, 994 hpa and 45-50 knots wind.
92L it's evident tropical storm like others insolit north Atlantic tropical cyclones over cold water and derived from exstratropical cyclone or cut off (Vince, Karl, Zeta, Ivan, Edouard, hurricane eight, ecc).
This is my final comment.

We were following 92L evolution with great interest from Spain... I would like to say that threshold values in Meteorology is a dangerous area.
As Daniele argues, 92L showed a warm core (I think shallow, of course), 994 hPa of minimun pressure and 45-50 KT winds close to the center. Even NHC assumed it was adquiring tropical characteristics.
In my opinión, if not named ANA, this little system has been very interesting. I would like to see another more in september - october, with a higher SST in that area..........................

Reminds me of a Nor' Easter off of the coast of North Carolina back in May of 2005...Sat picture saved by NWS Newport/Morehead City, NC of this system:

Write up on that Nor' Easter from same NWS office:

Wow.............. very interesting, Brunota
Extracting of that paper: "indicating that the smaller-scale circulation embedded within the synoptic extratropical system had probably obtained subtropical (hybrid) characteristics."
