MED: (Sub)Tropical Cyclone over the Mediterranean Sea

[DanieleItalyRm]

The second INVEST of this summer over the Mediterranean sea moved to east. probably it dissipate in the next 24h. Sea surface +26°C.

Where can i Follow tropical weather in the Mediterranean?

You're probably on it right now.

[DanieleItalyRm]

You will not be able to follow tropical weather in the Mediterranean, does not exist a chase..

These systems often seem to form in the same sorta way as the N.Atlantic systems you get sometimes in the autumn, colder air aloft which helps to increase the lapse rates enough to allow a warm cored system to form.

some people will say they are polar lows, and indeed some may well be, but some are IMO way too well defined to be anything other then real Tropical Cyclones.

Right! polar low? ignorance.. many of these systems are the same as Vince, Grace or Karl, same formation, same latitude, same time of year.. are the same thing.
But in this case only a INVEST for me..

It's not an "INVEST" since there is no agency officially putting out an ATCF file on it. More of an "area of interest".

[SEASON_CANCELED]

Hurricanes have happened in the med. before. It is extremely rare but they do happen.

Like Brazil gets them every one inawhile.

Who tagged this an invest if I may ask? Last I checked no agency tags invests in this region.

[CrazyC83]

What would they call it if officially declared one, 90M?

[Cryomaniac]

What would they call it if officially declared one, 90M?

Who knows, they seem to have settled on Q for the S.Atlantic.

[DanieleItalyRm]

Im Sorry I thought invest it was a simply: "The designation of a system as an invest does not correspond to any particular likelihood of development of the system into a tropical cyclone;"
But if a hurricane is formed we must say that it is not if it is not followed by the NHC, CPHC, or JTWC? This is wrong we have eyes to see.. They will never follow the mediterranean systems.
Distrurbance is more correct? "A discrete tropical weather system of apparently organized convection -- generally 100 to 300 nmi in diameter -- originating in the tropics or subtropics, having a nonfrontal migratory character, and maintaining its identity for 24 hours or more."

Yeah Invest is an official term so we can't use that here.

Med systems are interesting, would love to see research done on them.

I'm sure if one really developed and smahsed into somewhere like Rome and caused alot of damage it'd get alot of attention, then that maybe whats needed to get things going, abit like Catrina in the S.Atlantic.

in October 1996 this cyclone (call in italy mediterranean hurricane CORNELIA) produced floods, damages and 3 deads.. the wind exceded 140 km/h over Eolian islands:




In this summer, Another interesting disturbance (or like TD) occured over the central Adriatic Sea on 5 July (26°C sea surface); it's derived from a convectiv vortex over central italy:




And on 30 July over 25°C sea surface; it's derived from a well organizated convectiv complex over Balearic sea :



In August a probably TC occured over Black sea over 25°C sea surface:

SAB's Dvorak fix page now has a section for Mediterranean systems, which is a step forward. This came into effect yesterday:

Well thats interesting, perhaps this is the first step of the global agencies in taking seriously the potenial of the Med to produce at least TS/STS systems, if not the odd hurricane now and then.

[DanieleItalyRm]

I'm very happy !!

[AJC3]

I'm very happy

This is good! Please continue your excellent job of keeping the board informed about Mediterranean cyclones.

Ciao dagli Stati Uniti!

It's funny, a friend of mine is doing a seminar talk on exactly the 'Tropical Systems in the Mediterranean Sea? Yes/No' issue in a couple of weeks. Gonna be interesting to see which papers she's going to refer to.
