[Thunderstorms 2007] Caccia ai tornado Plains 2007: Nowcasting e forecasting

[griffa-petrucci]

Da ora vi invito qui a postare carte e radarate per il nowcasting e forecasting.
Vi dico subito che domani atterreremo a Oklahoma city alle 8pm locali e saremo nel bel mezzo di un probabile tornado outbreak. Purtroppo sarà troppo tardi per cacciare qualche supercella ma se riusciremo a prendere le valige e a noleggiare le macchine in un tempo ragionevole proveremo a cacciare qualcosa di notte; bisogna sottolineare che il cap dovrebbe tenere fino a sera tarda e la convezione potrebbe svilupparsi dopo le 8pm per cui in linea teorica potremmo anche vedere qualcosina, ma rimane una ipotesi remota.

In bocca al lupo ragazzi!

notizia da una mailing list sulle meteoriti

Greensburg, Kansas was hit with a tornado about an hour ago. There is
seven
miles of damage thrown around highway 54, around the downtown district.
The
hotal/diner is gone, the water tower is gone, the Big Well where the
1,000
lb. Brenham meteorite is/was located was hit....along with all the
buildings
around it. The main farming dealer lot was destroyed. Basically
everything
that was anything in Greensburg was hit.

I hope our Greensburg neighbors make it through the night, and that the
meteorite is intact.

This is pretty bad, glad I don't chase them anymore.

Salve a tutti!

E' iniziata l'avventura sulla Tornado Alley per i "nostri cacciatori".
Dovrebbero essere arrivati ormai da qualche ora in Oklahoma e in che situazioni, per le Plains!
Siamo, infatti, in pieno outbreak già da ieri, giornata che ha visto numerosi tornado e, haimè, anche vittime.
Vediamo quindi di riassumere queste ultime 2 giornate, una attualmente in atto visto il fuso orario.

Ieri ...

Da notare come il Kansas abbia subito le peggiori conseguenze con linee simili fra ieri ed oggi! Incredibile!!

Tornado snatches 1,000 pound pallasite meteorite

GREENSBURG, Kan. The tornado that razed the Kansas town of Greensburg
also
snatched one of its most valuable treasures. The thousand-pound Brenham
pallasite meteorite is gone.
Greensburg has drawn world-class meteorite hunters for decades to this
remote
Kansas hamlet. Trooper Ronald Knoefel says even the town's own
extensive
meteorite collection is gone.

And the town's other claim to fame -- the world's largest hand dug well
-- is
buried under a mountain of debris.

The nearby gift shop for the attraction had housed the famous
meteorite.

l'email da parte dello scopritore della meteorite

Hello List,

As many of you know, with my recoveries at the Brenham site, I bought
a
house in Greensburg, Kansas a while back as a location to base my
field work
from. I got a call last night from my brother in Wichita wanting to
be sure I
wasn't at my house in Greensburg, when the news of the tornado hit.
This last
week I was in Iowa on a hunt, and I was planning to return to Kansas
yesterday. At the last minute I decided to return to Arkansas first
instead of going
straight back to Kansas.

Reports are that 100% of Greensburg is damaged, and 70%+ of the
buildings
are destroyed, so I am expecting my home to be gone.

Of course I have dozens of close friends in and around Greensburg.
And my
heart and prayers go out to them. The uncertainty of their well being
as well
as the conditions of their homes is on the forefront of my mind.

The town is evacuated now, but I plan to get back up there as soon as
I can
this week.

Yesterday Greensburg's claim to fame was the world's largest hand dug
well,
and the 1,000 pound Brenham Meteorite they had on display. This
morning it
is "the Kansas town that got wiped off the map." It is amazing what
can
change in one night.

It is a reminder to all of us what is really important in life.

More news when I get it.
