Ailleurs dans le monde - Juin 2008


Recommended Posts

Ben nous ici mon cher Thierry, on se les pèle grave, pour parler comme les djeuns !

Par contre à Deming, dans le Nouveau Mexique, sud des Etats-Unis, il fait en ce moment 37°C (rien d'étonnant), mais en revanche, le point de rosée est apparemment aussi bas que -16°C !!!! donc une HR de 4% !!!! :blink: :blink:

Serait-ce encore un affaissement de la tropopause ??!!

Freak snowfall in Sweden

 

By Olafur Kr. Olafsson on May 23, 2008 in Countries, General, MBL, Sweden

 

Snow in SwedenA cold snap has caused confusion in Sweden, as heavy snow fell on northern parts of the country on Saturday. According to reports in The Local, weather forecasts predict the freak storm will bring the seasons last snow.

 

Residents, geared up for spring, were not expecting the large amount of snow, which caused large-scale power cuts.

 

Evelyn Nykvist in Sorskog told a local news agency: I am just heading out to shovel the snow, its feels a little tough. I measured this morning and 24 centimetres of snow had fallen during the morning.

 

The storm affected most of Dalarna as well as inner Halsingland, Harjedalen, Jamtland and the Are ski resorts.

 

The meteorological agency of Sweden, SMHI reported 14 to 15 centimetres of snowfall in Leksand, Malung and Rattvik in Dalarna.

 

Sten Laurin, a meteorologist for SMHI said: It has snowed quite a lot, as far south as parts of Varmland. Further south than that the snow turns into slush.

 

Residents in the affected areas were out on the streets on their bicycles the day before the storm and were left scrambling to locate their cold weather clothes the day after the unexpected snowfall.

 

Several cars were unable to handle the winter driving conditions in the Falun-Borlange area, most likely a result of having already removed their winter tyres.

2007-08 Ski Season a Record Breaker in the U.S.

News - Resorts

San Francisco, CA - Ski areas across the U.S. tallied 60.1 million visits for the 2007-08 ski and snowboard season, making it the best season on record according to preliminary estimates released Thursday at the National Ski Areas Association (NSAA) convention and trade show being held this week in San Francisco.

 

The new record represents a 9.1 percent increase from the 55.1 million visits recorded in 2006-07, and a 2.0 percent rise from the prior record of 58.9 million visits set in 2005-06.

 

All regions of the U.S. and resorts of all size categories contributed to the record season. The Northeast realized a 19.3 percent gain over last season, the Midwest rose by 12.3 percent, and the Pacific West improved by 10.0 percent. The Southeast gained a more moderate 6.5 percent and the Rocky Mountains, which set a record in 2006-07, topped that record this season by 2.3

 

percent.

 

Over the past 10 seasons, 1998-99 to 2007-08, the average number of visits recorded nationally was 56.16 million. The 2007-08 season represents a 7.0 percent increase from this 10-year average. By region, the Northeast was up 9.0 percent from its 10-year average of 12.91 million visits, tallying 14.07 million visits this season. The Midwest, with 8.09 million visits, was up 10.1 percent, the Rockies were up 9.9 percent with 21.33 million visits, the Pacific West was up 1.4 percent with 11.37 million visits and the Southeast was down 1.3 percent with 5.21 million visits in 2007-08.

 

:blink: The study cites strong increases in snowfall as a contributor to the record season. Snowfall in the Pacific West was up 62 percent, up 39 percent in the Rocky Mountains, up 35 percent in the Midwest, and up 26 percent in the Northeast. Only the Southeast reported a decrease, down 7 percent.

 

A final report will be issued by the NSAA in July.

Global Cooling Continues for May 2008

 

June 2, 2008

May 2008 Was Another Cold Month

By Joseph DAleo, CCM

For more than 75% of the nation, May was cooler than normal, as much as 6F below in the far North Central.

This is in sharp contrast to May 2007 which was warm in the same areas it was cold this year. May 2007 was the 11th warmest May for the US.

may_2007_thumb.jpg

 

We will see in a few days where this May ranks. Clearly it will be colder than normal. UAH MSU daily data suggests the global average will be well below last year as well. Stay tuned for official updates.

 

That should continue the downslide we have seen starting in 2002 which accelerated the last year with the Pacific cooling and La Nina. Meanwhile Antarctic ice remains at 1 million square kilometers ahead of last year at this time and ahead of the average since 1979. If it stays at this anomaly, we will surpass the record set late last winter there. The arctic ice is similar to late May at this time after recovering nicely this past winter from record low levels in September and October. Only time will tell whether the same flow patterns will develop in June that developed last year to rapidly diminish the ice. See more here.

2008 SUMMER FORCAST ( BRETT FROM ACCUWEATHER )

 

After sorting through global land and ocean data, long range models and past climate I have finally come up with a summer 2008 forecast for Canada. Some of the more key things that I have considered.......

 

--A fading La Nina

--A cool phase of the PDO (Pacific Decadal Oscillation)

--Much of the North Atlantic having above-normal sea-surface temperatures.

--Cooler-than- normal Pacific waters from the Gulf of Alaska to the U.S. West coast and off of Baja (part of the cool phase PDO)

--Drier-than-normal ground southern prairies.

--I expect a more active Atlantic tropical storm/hurricane season with a greater than normal threat to Atlantic Canada, especially in late- August and September.

--The mean position of the U.S. high Plains ridge of high pressure will allow a greater than normal amount of thunderstorm complexes to track from the central Plains to the Great Lakes as they run along the "rim of the ridge"

 

 

The top map shows my prediction for temperatures across Canada for the summer as a whole. The red areas are above normal, green near normal and blue is below normal.

PRECIP FORCAST FOR SUMMER 2008 (BRETT ACCUWEATHER )

 

The second map below shows what I expect for summer precipitation. Keep in mind summer precipitation can vary greatly over short distances due to the convective (showers/t-storms) nature of precipitation. The neon green color indicates above-normal rainfall, the base green color indicates near-normal, while the yellow/brown color shows where I expect the summer to be drier than normal.

On a un bel exemple ici d'une oscillation climatique décadale superposée par-dessus la tendance du réchauffement climatique. Je ne sais pas quelle est la période utilisée pour calculer les normales. As-tu des infos?

Voici le tableau statistiques de l'année 2008 (au 31 mai), concernant les tornades aux USA. C'est certain qu'il reste du ménage à faire pour enlever les rapports multiples de chaque évènement (doublon et plus), il en demeure pas moins que même en divisant par deux le total actuel, c'est la saison la plus active depuis longtemps - sinon la plus active en nombre de tornades jusqu'à maintenant. Depuis janvier, 2008 est nettement au dessus de la moyenne et l'écart semble s'agrandir.

C'est drôle, avec toute cette grisaille qui sévit sur Vancouver la plupart du temps, je me suis mis à penser au moment où je suis arrivé ici... c'était le 17 mai dernier, et il faisait très chaud et humide... 29°C en fin d'après-midi. C'était une merveilleuse arrivée, et ça donnait une très belle image de Vancouver! Tropical! La journée d'après fut merveilleuse aussi. Toutefois, depuis ce temps-là, je dois dire que les journées complètement ensoleillées sont excessivement rares (2 jours depuis ce fameux 17 mai). Tendance générale: les avant-midis sont généralement nuageux, et les après-midis nous donnent du soleil, souvent même lorsque les prévisions météo n'en donnent pas. Malgré tous ces nuages, il n'a pas plu souvent, et encore moins en termes de quantité. Et là, avec les prévisions pour la semaine, c'est plus que décourageant! Juin, juillet et août à Vancouver sont supposés être chauds et secs. Ça commence mal. :) Mais bon, pour en revenir au 17 mai, j'ai consulté les données de l'aéroport de Vancouver pour voir à quel point c'était exceptionnel ou pas cette chaleur. Les données commencent en 1937. Le maximum enregistré le 17 mai 2008 est de 29.2°C, ce qui en fait la deuxième plus grande marque en mai pour Vancouver, après le 30.4°C de 1983. La 3e marque est 28.9°C le 21 mai 1963 et la 4e marque est 28.3°C le 16 mai 2006. Sinon, en mai, les records de chaleur sont entre 24 et 26°C. Sans le savoir, je suis arrivé à Vancouver lors d'une journée particulièrement exceptionnelle, car les 29°C sont tout sauf communs ici!

en ce 4 juin il neige a snowbird en utah depuis ce matin 4 pouce d'accumulation :( jusqu'a 10 pouce de prevu

Ça n'a rien d'exceptionnel d'avoir de la neige dans les rocheuses à ce temps ci de l'année.

 

Le centre de ski Snowbird en Utah est à 3350 mètres (11,000 pieds) d'altitudes et il y neige jusqu'en juin. La saison de ski se termine rarement avant la première semaine de juin - et il y a même des aventureux qui y font du ski en juillet entre les rochers.

The National Snow and Ice Data Center has just released their latest update (month of May) on the sea ice situation up in the Arctic. Here are some of the main highlights from their report.....

 

Arctic sea-ice situation

 

--Sea ice extent is below the long-term average.

--Sea ice extent is very close to the low levels seen in May 2007. (May 2008 extent was 0.11 million sq. miles greater than May 2007).

--Spring ice cover is thin.

--The average decline rate this May was 3000 sq. miles per day faster than May 2007.

--The average Arctic Ocean surface air temperatures in May were 1 to 3 degrees celsius (2 to 5 degrees F) above normal.

--Thin ice that covers the Arctic Ocean is showing signs of early breakup.

--There is a distinct lack of thick, resilient multi-year ice, but the thin ice is farther north than normal, which may make it less vunerable than if it was in its normal position.

Tornados, Flooding May Warn Of Climate Change

 

(Jun. 4, 2008) Record-keeping meteorologists at the National Oceanographic and Atmospheric Administration say this years tornado season is one of the deadliest in a decade and may be on pace to set a record for the most tornadoes. And flooding in the Midwest has been at 100-year levels this spring.

 

 

There is considerable concern that climate change due to greenhouse gases species increasing will lead to the enhancement of strong, large storms occurrences, such as hurricanes that also spawn tornadoes when they occur. Increased storm strengths also bring flooding events, he said.

 

Gaffney and co-researcher Nancy A. Marley are currently involved in a three-year investigation of aerosols tiny particles suspended in the air and their role in climate change.*

 

Tornadoes are short-lived events and, until recently, scientists had to depend on limited ground observations to study them. Satellites and radar systems are now enhancing researchers ability to see their number and strength in detail. But short lived tornadoes are hard to tie directly to climate change due to the limited climatology of tornadoes.

 

Weather forecasters have examined El Niño and La Niña, important temperature fluctuations in surface waters of the tropical eastern Pacific Ocean, as a potential for past tornado activities in the U.S.

 

The data available from NOAA do not support a strong statistical significance to data for direct effects of El Niño or La Niña on frequency or strength of tornadoes, Gaffney said. Although, there is considerable concern that climate change due to greenhouse species will lead to significant changes in weather patterns, these currently available data are not conclusive.

 

He said the Intergovernmental Panel on Climate Changes report on severe weather events discusses the topics backed up by NOAA data.

 

Basic thought is theres more energy in the atmosphere, more water vapor evaporating and greater likelihood for stronger heating events that lead to stronger thunderstorms - super cells, that can lead to tornado production, Gaffney said.

 

He said tornadoes are complex phenomena that are linked to the number of super cells and their storm strengths. Flooding events are more wide spread than tornadoes, and are more readily tied to climate predictions than tornadoes.

 

What we are looking to see, in current and future research and data acquisition, is whether the frequency and strength of tornadoes change as we continue to increase the energy distribution in the atmosphere, he said. Currently, this year is looking to be significantly larger in the number of tornadoes seen than in the past few years. That and the record floods that are associated with these strong storm systems, may be a warning of things to come. But more data gathering is needed.

 

Gaffney points to the improved Doppler radar systems that have allowed tornado warning times to be advanced as the main tool for gathering this tornado climatology that will be needed to evaluate links between climate change and severe weather events.

 

*The $625,000 study is funded by the Department of Energy Atmospheric Science Program. He and Marley will discuss severe weather and links to climate during their annual orientation for the DOE Global Change Education Program.

en fait 17 tornado watches/warnings!!!

avertissements ou veilles... ce serait mieux, merci. :(

Désolée...Les mots me manquaient... :wacko: :D

 

toujours est-il qu'il devrait y avoir beaucoup d'action aujourd'hui aux états...selon le SPC en tout cas! à suivre...Je vais que les équipes de Tornadovideos.net et severestudios.com seront en direct, pour ceux que ça intéresse...de plus, l'équipe numéro 1 de tornadovideos devrait essayer de déployer une deuxième fois son "probe"! à voir!

Vraiment pas encourageant ! :) Je sais pas vous, mais moi sincèrement ça me fait ch...! Et mon sentiment n'est rien à côté de celui des populations des Maldives ou du Bangladesh qui, elles, vont être les premières à subir de plein fouet les conséquences désormais malheureusement inéluctables de ce maudit réchauffement climatique...

 

Iceberg, pourrais-tu ste plait m'envoyer le lien de la NOAA du suivi de la cryosphère, je ne parviens pas à l'atteindre... merci !

J'aurais plutôt dit '' Ha! vielen Dank sehr geehrter Herr '' :D

Mein geehrter Réjean, ich bin ganz beeindruckt !! Es ist sehr selten dass Quebec bewöhner deutsch sprechen können ! :)

Na ja, auf französisch wäre es vielleicht besser für den anderen... ;)

 

donc je disais qu'il était peut-être préférable de poursuivre en français, non ? :blink:

 

 

Donc voici ce que j'ai trouvé sur weather underground : c'était avant-hier dans le parc du YellowStone, magnifique n'est ce pas ? la végétation commence à peine, mais il ne faut pas oublier que l'atitude est élevée : 2000m ....

Tatsächlich :D

 

C'est le peu que je sache et ça vient de mon grand père du temps où il acceuillait les Allemands qui venaient installer de la machinerie dans les moulins à papier - on parle ici des années 1920 à 1930. C'est pas jeune, mais j'ai retenue ça de lui, en plus des chiffres de 1 à 10. Il parlait aussi le Finlandais, mais ça j'ai jamais rien compris :)

 

Effectivement superbe paysage et j'en ai vu plusieurs aussi durant notre voyage près du désert. C'est tellement grandiose. aahhhhhhhh (grand soupir)..

 

Bonne journée vieux (ou jeune) :blink:
