Spektakularen mezocklon in wall cloud v Furlaniji, 7. junij 2009

[markokorosec.net]

Ta zadnji vikend je bil naravnost za zgodovino. 9 supercelic v 24 urah, 2 funnel cloud-a in izjemne strukture. Kot da jih v soboto ni bilo dovolj, je bil v nedeljo spet izjemen chase dan. Tokrat počasnejše celice, a strig še vedno ugoden za razvoj supercelic. Če bi le bil prizemni strig močnejši, pa bi tornado povrgla. Ta prva mrcina je moja top5 struktura kariere... naravnost spektakularna je bila! Ker enostavno nimam časa tacat teksta, bom kar prilepil reportažo v angleščini... pa saj znamo vsi angleško, ne bo problema se kaj novega naučit

Spodaj sledi detajlni opis, tule so pavse slike v galeriji: http://www.weather-photos.net/gallery/thumbnails.php?album=269

Still pretty sheary and unstable conditions in place after an outbreak a day ago and few more severe storms were expected in Friuli region. I noticed a wild storm forming on radar NW of Pordenone and soon went towards it. It was clear this is going into supercell mode, its motion vector was inclined away from the main flow. Meanwhile driving towards Palmanova, a nice looking towers were on going towards western Slovenia with a cute wavy stratus deck undulating over...





I couldn't see my targeting storm from my home, but I already noticed it near Palmanova. Surprisedly it was going pretty slow and that was the best for calm approaching towards it. I dropped SW towards Latisana and Portogruaro via A4. First stop near Porpetto cleary shows its well organized structure with sharp updraft towers and anvil aloft, weakly striated structure visible as well. A closer look showed there is a monster LL mesocyclone with wall cloud beneath it... and I wasn't loosing time here for long...





It was becoming more and more impressive when I was already near Latisana... WOW what a low wall cloud monster, massive inflow tail and FFD way away from the updraft tower... perfect!







Closer look into the rapidly blasting inflow tail into the wall cloud...



I went a bit further, but had no reason to hurry now as it was really slow and in that moment still well NW of Portogruaro where I planned to exit the A4. These three image sequence nicely show how spectacular the whole structure was... first the whole system, then mesocyclone zoom and again insanely low level inflow tail close-up...







Oh man, if only such storm would have been formed a day before in that incredible LL shear and lower LCL heights... that would easily drop a tube onto the ground. Anyways, enough of utopia... have had LL winds/shear as they were there, weak to moderate according to 12z Udine skew-t. I moved forward for a few kms and wall cloud there was actually even lower than it was before... I couldn't see the ground due to a bit more vegetation, but definatelly it was dragged almost on the ground! Again zooming in...







I was already close to Portogruaro exit in the next minutes and took this shot just before I went off the A4...



Two photos taken at Portogruaro exit... I was right under the meso and when I stopped for a minute, I could already hear a large hail (reported near 5cm in diameter) roaring to my NW. Soon it started with large drops and I rapidly moved south into the city and then turned E on the road towards Latisana.





I wanted to go a bit further east, just to be well in front of the meso with better view over the whole monster. I couldn't see the meso in the mirror, also traffic was terrible there... anyways I stopped in a good open field and jumped out... holy s**t there was a majestic mesocyclone with spectacular striations and robust rain free base... I was speechless, mothership beauty!! Was just drolling over the structure and let the photos say it all...







I stayed there for a few minutes while noticed the mesocyclone wants to occlude soon, so I moved a bit more to the east to take few more pictures before it collapses. Still pretty beautiful striated meso, but well seen it was collapsing rapidly... it then got more outflow dominant and I say bye bye to my baby.



I then noticed few more cells firing along its outflow boundary convergence with sea breeze in the back and intercepted them a bit east of Portogruaro. For some time this new cell was was trying with a weak mesocyclone, but never generated a strong wall cloud... it was more an outflow dominant storm trough its whole cycle, but colors were amazing. I took a few shots of its structure...







About 30min later it was somehow trying to organize again, infow tail/clouds were rapidly taking place... looked like it was trying to cycle a bit and actually it made it further north of me, but I wasn't too impressed and gave up with it. Also I wasn't expecting much afterall, as the first monster supercell well mixed and cooled the air, so the warm juice was gone.



At sunset a nice tower poped up just west of me, nothing serious... but colors were cool...



I call it the end of day, though I saw a new cell firing more in the back. I jumped again onto A4 in Latisana towards home and had a clear view over that isolated cell it the back. Surprisedly it was working on the meso and wall cloud. Nicely defined also with an inflow tail forming... just a few more shots and the day was completed.

Happy with the evolution, got another 3 supercells and counting 9 supercells with 2 funnels in 24 hrs... pretty wild weekend for our regions... once again, Friuli simply rocks!

Vaou, kako lep mezociklon si ujel Marko, tista cirkulacija oblakov v polkrožni obliki je pa ena najlepših slik, kar sem jih videl v tem mesecu! 

Lepo.

Ma ti si profi

Mogoče je pa naš @Skywarn v Ameriki

[Aquatic]

Neverjetno s kakšnim žarom nam @Skywarn prikazuje reportaže. Še pred parimi let so priznani strokovnjaki zatrjevali, da za nastanek takih vremenskih pojavov v naši bližini ni potrebnih pogojev.
We want more.

Kjere strukture...

Mojster Mare. 

[Capillatus]

Odlično  
Zelo lepe strukture  

A prva supercelica je bila LP ali klasična?   Se nekako bolj nagibam k LP  
Toda tist mothership je bolj za klasično ali HP značilen če se ne motim

Damn  
Čestitke še enkrat več za ujeto v objektiv in razlago  

[urbang]

super poslikano

Mega slike!

Saj si že sam sebe zabil...

Bila je klasična supercelica z "mothership" strukturo mezociklona...

[maestro]

Nisem si mislu, da take mrcine nastajajo tako blizu nas...

[Cumulonimbus]

Tako kot si že sam povedal, je šibak prizemni strig rešil tiste predele pred uničujočim tornadom, ker tule se pa po slikah vidi, da se ne gre šaliti, saj bi ob morebitnem močnejšem prizemnem strigu, celica povrgla strahoten tornado na tla, ki bi zagotovo razdejal bližnjo okolico in ogrozil življenja tam živečih ljudi

Joooj, a se res ne da enkrat s tabo?!

Joooj, a se res ne da enkrat s tabo?!

Ampak res  !S tabo mora biti pa res najbolj uživantsko (z stalnim pogledom v radar) na Chase.Uživaj in komaj čakam na še  .
