09.06.1984: CENTRAL RUSSIA OUTBREAK

Bild
photo: Ivanovo-Tornado (F5) [Komsomol'skaya Pravda Ivanovo]

data (status: 24.03.2007, 1st update):

- up to 22 (current thinking!) tornadoes occured in the embedded area of Rybinsk-Tver'-Moscow-Rjazan-Penza-Samara-Kazan-Vjatka-Vologda (~400.000 km²)
- duration: up to 8 hours (start ~0900 UTC / ending ~1700 UTC)
- highest activity began ~1130 UTC and ended ~1430 UTC
- at least two violent tornadoes (F5 and F4) and at least one F3 were produced
- occurence of strong and violent tornadoes mostly took place simultaneously (from ~1100 UTC to ~1430 UTC)
- path direction: SSW -> NNE / later on from S -> N (~1300 UTC)
- at least 400 people were killed throughout tornado occurence
- at least 1.500 houses were destroyed / at least 500 houses demaged
- at least 30 villages and 6 towns/cities were affected
- current thinking is that demages totally amounts billions of Rubels


- current thinking is to split the events of Rostov/Danilov and Vetluga/Ponazyrevo into four single cases because of the long distances between these villages/towns. The city of Jaroslavl' is situated straightly between Danilov (north) and Rostov (south), but the city was not hit by a tornado, so Rostov and Danilov were two different cases (?). The other cases (Vetluga/Ponazyrevo) can be more expected as two single cases: distance between both places is ~120 km in NW-direction. Thuderstorms shifted northward in this region, so these two events are more than likely two single events. So, 22 tornadoes probably occured on 09.06.1984.

24.06.1967: Tornado outbreak in the North of France, Belgium and Netherland

on June 23, large storms of hail on the south of the department of North. Several tornadoes of low intensity are announced. On June 24, very violent one storms in evening. Preceded by violent gusts of wind and falls by let us hail reaching 7 to 8 cm, two force tornadoes F4 and F5 (Palluel) devastates the south of Pas-de-Calais and the department of North: a multitude of houses, even out of bricks, are purely and simply shaven, of the trains are moved, the cars are carried in the airs, as well as whole herds of cows. The tornado F5 [...] even carried in the airs a whole house with its two occupants, found died in the middle of the debris of their dwelling which had landed a little further in a marsh. Assessment: 7 died, a hundred casualties, more than one thousand of homeless person and property damages considerable. This tornado F5 de Palluel was the most violent tornado of the XXème century in Western Europe. On June 25, new and violent one storms on the whole of North and Pas-de-Calais and several tornadoes, including two F3: hundreds of houses are destroyed, from the thousands of trees are torn off, many destroyed harvests. Trees centenaries are carried in the airs like “wisp of straws” (expression of a witness)! According to the file of the Weather Association of the Nord/Pas-de-Calais Area.

24 june 1967

1. Davenescourt (France) / F3 /Path Length: 8 km / Path Width: 400 m / 18h40 UTC
2. Palluel (France) / F5 /Path Length: 23 km / Path Width: 250 m / 18h40 UTC

3. Pommereuil (France) / F4 /Path Length: 23 km / Path Width: 2500 m / 18h40 UTC


25 june 1967

4 Argoules (France) / F2 /Path Length: 12 km / Path Width: 150 m / 11h45 UTC

5 Tricht (Netherland)/ F4 /Path Length: 11 km / Path Width: ? /

During the 25th the first tornado touched-down close to the Dutch border in northern Belgium where more than half of the 907 homes in Oostmalle were damaged or destroyed. The second tornado touched-down just over the Dutch border roughly halfway between the towns of Breda and Tilburg. In this area the tornado tracked for 11 km and whilst there were very few buildings along the tornado track many trees were blown down and two people at a campsite in Chaam were killed. A third tornado then touched-down, this time for 15 km, a little further north in the central Netherlands where this tornado tracked from Nieuwaal, near Zaltbommel to Tricht, near Geldermalsen. This time there were both more witnesses and more damage, most notably at a housing estate in Tricht where around 100 houses were damaged or destroyed and five people were killed.

6 Oostmalle (Belgium)/ F? /Path Length: ? / Path Width: ? /

At Oostmalle, 10 miles northeast of Antwerp, many homes were destroyed, dozens of cars overturned, and two people were killed. Others died in the Netherlands on the 25th and in France on the 24th.

The second tornado touched-down just over the Dutch border roughly halfway between the towns of Breda and Tilburg. The tornado tracked for 11 km and whilst there were very few buildings in the path many trees were blown down and two people at a campsite in Chaam were killed.

A third tornado then touched-down, this time for 15 km, a little further north in the central Netherlands (Wessels 1968). This time there were more witnesses and more damage occurred, most notably at a housing estate in Tricht where around 100 houses were damaged or destroyed and five people were killed.

The same system produced tornadoes over parts of north-eastern France the previous evening killing eight people and injuring 80. These tornadoes were two of the region’s most violent ever (Meaden 1985), whilst on the 25th another tornado may touched down in western Belgium (Wessels 1968).

Hello Rémy,

24.06.1967:

Thank you for the list and details. I've been to the ExtremeWeatherCongress in Hamburg last thursday and friday - there was a seminar report about 1967. Thunderstorm activities and tornado occurence was probably given from 24.06. and 25.06.1967, so we may can list the events in France with those in Belgium and Netherlands as one outbreak with a duration of 48 hours.
What do you think about that?

regards,

I am agree with you and I will modify my message to make the list of the events of Belgium of the Netherlands and France of June 24, 1967 to June 25, 1967. Just a question. Where you found the photographs and all the details of the outbreak of Russia? There is you a book or a work which I could obtain ? Thanks again for the picture of the tornado of Ivanovo

04.05.1961: Tornado outbreak in North France.

1 Sainville (Seine et Marne) / F? /Path Length: ?/ Path Width: ? / 17 h 00 loc.

2 Cormeilles (Calvado) / F3 / Path Length: 20 km / Path Width: ? / 17 h 20 loc. / 2 dead and 3 injured

3 Evreux (Eure) / F3 / path length: 8 km / path width: 500 m / 18 h 20 loc./ 1 dead 100 injured

Celebrate and present on a number of specialized publications, this waterspout is to my knowledge the only one in France which one could highlight the multiple vortices (in particular thanks to a famous photograph. See post Photographs and vidéos low). Formed in the afternoon during a storm with hail, it killed a person and in wounded 100 others on a course of 8 km and a width of 500 Mr. According to a Net surfer whose father saw the waterspout, it would have passed in full centre town (whereas Evreux would be located in a basin).

23.11. 1981 - Tornado outbreak in England

Bild

On 23.11 1981, a deep low formed to the west of Southern Norway.
Its center already lied nearby the upperlow core, no further significant deepening could be expected. However, corresponding cold front stretching over England was situated ahead of a striking trough axis over Ireland and Wales.

Upper flow has been rather strong and intensified the advection of cyclonic curvature vorticity ahead of the trough axis. Cold front propagated southeastward while the upperflow was directed to the northeast. As a result, rather dry air masses overlapped moist and warm air masses in the convective boundary layers, see the sounding of Cambourne

http://weather.uwyo.edu/upperair/images ... .skewt.gif

It reveals a broad area of potential instability sitting above of 800mb that could be released by the strong upward motions ahead of the trough axis respectively ahead of the cold front.

Hence, a preparatory shallow squall line consisting of not electrified showers formed, perhaps as a line echo wave pattern with bowing segments, crossing England during the afternoon hours. 105 mostly short-lived and weak tornadoes developed within only five hours in a bounded area in England, few were F2-rated.

Perhaps, most of the tornadoes formed at the leading edge of the squall line, as discussed in this paper of Atkins (2005).

http://www.mmm.ucar.edu/wrf/users/works ... Atkins.pdf

Thus, it would have been nonmesocyclonic tornadogenesis.

On the other side, sounding of cambourne indicates a larger area of potential instability and rather high vertical wind shear, perhaps with backing winds ahead of the squall line.

In any case, it is not possible to filter out the type (mesocyclonic or nonmesocyclonic) of tornadogenesis yet.

More information and references to this outbreak can be found in the synoptic forum of UK Weatherworld (registration required)

Cheers,
Felix

Hi,

may we please start new threads for single tornadoes around europe and post here only the outbreaks (at least 6 tornadoes in a short time in a small region?

Thx, Thomas Sävert

Hi Thomas,

you are right. We should better post only tornado outbreaks here. I will open a new topic for violent or severe tornado events in Europe.

@Rémy:

I will open a new topic for violent or severe tornado events in Europe, so we can discuss single tornado events (non-outbreaks) there.

The new topic is online.

Let us deal with violent (F4 and F5) and also with severely strong tornadoes (F3).

@Rémy:

please copy your analysis about 16.06.1957, 04.05.1961, the single case of Neede 1927 and the Portugese one and post it in the new created forum.
When you have finished it, please delete the single case studies in this topic here.
Thx ;)

We should only deal with tornado outbreaks here, otherwise it might be too unclear.

regards,
Thilo
