Hey guys,
I just came across this on the UK Met office site. This is not the first
occurrence of such a system, and wondered if any of you had any thoughts on
these Mediterranean storms?

Visible imagery is at this url:

And a hi-res image is he
http://www.met-office.gov.uk/sec2/se...medtc2003b.gif

This storm occurred on the 17th - 18th September this year. Any details on
this or past occurrences (I.e. the storm of 15 - 16 January 1995) would be
appreciated.

Thanks

Hmmm, looks a little disorganized. More like a tropical depression.

Looks to me like nothing more than an Mesoscale convective vortex (MCV) from
a t-storm complex that moved offshore from Tunisia. You're simply getting
diurnal redevelopment around the mid level circulation. You can tell this by
the types of clouds being observed, the fact that the system has a closed
mid level center before it even moves offshore, and the fact that it
dissipated by the 19th. Definitely not a tropical surface based cyclone, nor
one born from Mediterranean waters.

You cld be right Evert.However,the following refers to a cyclone development that spun up in almost
exactly the same position on the Algerian coast in early October 1996.The satellite pictures
reproduced do seem to indicate a more organised system than the present one.It's an interesting idea
an MCV spawning this sort of system in the Med'-I haven't seen it mentioned in the literature.
http://www.ictp.trieste.it/cgi-bin/I...words=IC98007*
A TROPICAL-LIKE CYCLONE IN THE EXTRATROPICS by Oreste Reale and Robert Atlas
published in Weather & Forecasting V16p7
ABSTRACT: Between 4 and 9 October 1996 two sub-synoptic scale cyclones developed over the
western-central Mediterranean, causing floods, strong winds and severe damage. Satellite imagery
revealed two intensely convective vortices during this period with a spiral structure, the second of
which also displayed a well defined eye. The corresponding NCEP analyses, although limited by
$1^{0}$ resolution, also displayed the ³signature² of two tropical-like cyclones. These features
were particularly evident in the second event (7-9 October 1996) and included small-scale, alignment
between the cutoffs at all levels with the sea level pressure minimum, and a warm core from the
surface to the tropopause.The wind speed vertical sections in the meridional and zonal directions
corresponding to the eye revealed a virtually motionless column of air. The causative mechanism
detected for the October 1996 events is barotropic instability (produced by very strong horizontal
shear in the midtroposphere), enhanced by low-level convergence and upper-lever divergence and
latent heat release through intense cumulus convection. These findings suggest the need for a new
category in the classification of Mediterranean cyclones.

Aw, you take all the fun out of it. I spent three years forecasting weather
near Adana Turkey (Incirlik) and watched a very interesting vortex spin into
Cairo Egypt one time. Moved due south smack into the Nile delta. Sure wish
I had satellite loop and the HECA obs to post. Lots of flooding and loss of
life if I remember correctly. Sometime between 1993 and 1995. It was
perhaps late summer in '94 or '95. MB

Cool, a MARK IVB hi-res image. How'd you get that?
