ATL : TROPICAL STORM GRACE
Moderator: S2k Moderators
Re: ATL : Invest 90L
Where are you getting those QuikSCATs? Those are old, as the system is not as close to the Azores now as it was. The OPC analyzes the system as a 998-mb gale center from an occluded front:
So does the UK Met Office (not shown). Also, unlike a pure tropical system, the wide extent of higher winds north of the center is not typical of a tropical system and suggests much of this comes from the gradient between it and a 1023-mb high to the north. The convection is highly asymmetric and mostly to the north and east of the center
Also, as stated above, any warm core is very shallow, as the 500-mb analysis shows (note that this is a TIF file).

OLd?? this is the ultime two Quickscat! no old.

These system very like at many north atlantic tropical cyclones (Vince, Karl, Unnamed, ecc.).. In particular cases cut off col core become in warm core tropical cylone.
The last nighy the convection present in the perfect center. Today convection asymmetric, but the asymmetric convection common in many tropical storm or depression:
90L 35 knots
90L 35 knots

I'm not sure if it is warm core it looks waaaaay better than Danny did.

thunderstorm activity and convections is impossible in a cold core cyclone center, only in warm core cyclone possible.

The disturbance passed North of Ponta Delgada METAR:

The maximum gust was 70km/h, but well away from the center.

That's definitely not true... convection is certainly possible in cold core systems.

Curious that this perturbation after the loop to north yesterday and today return to a slightly lower latitude has recreated again the eye-like feature we have seen 2 days ago. Very exotic system with only 50 km radius

please you can post a cyclone cold core with mesocyclone thunderstorm -covective center?
and however it is not this case.
