el nino power !! (Jan. 28, 2008) The next time you have to raise your umbrella against torrents of cold winter rain, you may have a remote weather phenomenon to thank that many may know by name as El Nino, but may not well understand. Researchers now believe that some of the most intense winter storm activity over parts of the United States may be set in motion from changes in the surface waters of far-flung parts of the Pacific Ocean. Siegfried Schubert of NASA's Goddard Space Flight Center in Greenbelt, Md., and his colleagues studied the impact that El Niño-Southern Oscillation (ENSO) events have on the most intense U.S. winter storms. An ENSO episode typically consists of an El Niño phase followed by a La Niña phase. During the El Niño phase, eastern Pacific temperatures near the equator are warmer than normal, while during the La Niña phase the same waters are colder than normal. These fluctuations in Pacific Ocean temperatures are accompanied with fluctuations in air pressure known as the Southern Oscillation. ENSO is a coupled ocean-atmosphere effect that has a sweeping influence on weather around the world. Scientists found that during El Niño winters, the position of the jet stream is altered from its normal position and, in the U.S., storm activity tends to be more intense in several regions: the West Coast, Gulf States and the Southeast. They estimate, for example, that certain particularly intense Gulf Coast storms that occur, on average, only once every 20 years would occur in half that time under long-lasting El Niño conditions. In contrast, under long-lasting La Nina conditions, the same storms would occur on average only about once in 30 years. A related study was published this month in the American Meteorological Society's Journal of Climate. The scientists examined daily records of snow and rainfall events over 49 U.S. winters, from 1949-1997, together with results from computer model simulations. According to Schubert, the distant temperature fluctuations in Pacific Ocean surface waters near the equator are likely responsible for many of the year-to-year changes in the occurrence of the most intense wintertime storms. "By studying the history of individual storms, we've made connections between changes in precipitation in the U.S. and ENSO events in the Pacific," said Schubert, a meteorologist and lead author of the study. "We can say that there is an increase in the probability that a severe winter storm will affect regions of the U.S. if there is an El Niño event." "Looking at the link between large-scale changes in climate and severe weather systems is an emerging area in climate research that affects people and resources all over the world," said Schubert. "Researchers in the past have tended to look at changes in local rainfall and snow statistics and not make the connections to related changes in the broader storm systems and the links to far away sources. We found that our models are now able to mimic the changes in the storms that occurred over the last half century. That can help us understand the reasons for those changes, as well as improve our estimates of the likelihood that stronger storms will occur." El Niño events, which tend to climax during northern hemisphere winters, are a prime example of how the ocean and atmosphere combine to affect climate and weather, according to Schubert. During an El Niño, warm waters from the western Pacific move into the central and eastern equatorial Pacific, spurred by changes in the surface wind and in the ocean currents. The higher sea surface temperatures in the eastern equatorial Pacific increase rainfall there, which alters the positions of the jet streams in both the northern and southern hemispheres. That in turn affects weather in the U.S. and around the world. Scientists have known about El Niño weather fluctuations over a large portion of the world since the early 1950s. They occur in cycles every three to seven years, changing rain patterns that can trigger flooding as well as drought. Schubert cautions against directly linking a particular heavy storm event to El Niño with absolute certainty. "This study is really about the causes for the changes in probability that you'll have stronger storms, not about the causes of individual storms," he said. For that matter, Schubert also discourages linking a particularly intense storm to global warming with complete certainty. "Our study shows that when tropical ocean surface temperature data is factored in, our models now allow us to estimate the likelihood of intense winter storms much better than we can from the limited records of atmospheric observations alone, especially when studying the most intense weather events such as those associated with ENSO," said Schubert. "But, improved predictions of the probability of intense U.S. winter storms will first require that we produce more reliable ENSO forecasts." NASA's Global Modeling and Assimilation Office is, in fact, doing just that by developing both an improved coupled ocean-atmosphere-land model and comprehensive data, combining space-based and in situ measurements of the atmosphere, ocean and land, necessary to improve short term climate predictions.

En Chine !! Snow storm brings China to a halt January 28 2008 15:19 China's transport and energy systems have been caught in a perfect winter storm, with hundreds of thousands of people stranded during the peak travel season after train delays caused by heavy snow and power failures. The power crisis, the worst in China for many years, has been caused by an acute shortage of the supply of coal, the country's staple fuel. The problem has been amplified by unseasonally large snowfalls in northern and central China

En cette date 1805 du 26 aux 28 Janvier. THE FORTY -EIGHT -HOUR- SNOW AT NEW YORK CITY. New York's longtime weaterman Henry Laight described the storm scene in his notes: jan.26,1805-- It began to snow in the eveing of this day and continued until the eveing of the 28th without interruption--48 hours. So much snow has not fallen at one time for a great number of years. Pine St, Cedar St, Liberty St.and many narrow streets are altogether impassable for the sleighs on account of the great depth of the snow.The snow must be at least 3 feet deep. H.Laight. Ms.Met. Obs... (N.Y. Hist. Soc.)

As i stated in my last entry on the coldest day in Windsor Ontario like i said more research would be done well ive found one date to be colder then the last one of 1859 Jan 10 the low of - 30.0c. Well in 1784 La Côte de Misère (Poverty Coast) later named Windsor Ontario in the 1850s. A record low of -32f or -35.5c was set on Jan 27 1784. The temperature was taken by (George C. Anthon) (m.d.) A meteorological journal kept at Upper Canada territory from Aug. 1781 to May 1786 inclusive..it was truly a outstanding winter for the lower great lakes area.This is what the log said on that record cold day that still stands today.(0700) -32f (1200) -28f (2000) -24f (excessive cold.serene weather). I will point out that the winter of 1740-41 was also another severe winter in the area mentioned above and further research will be done to see if it surpasses the severe winter of 1784. In the near future i will be posting a classification of winters in order from the VERY SEVERE to SEVERE in the 1700s then 1800s and 1900s. Then i will class the all time winters in order of severity.

Observations were made in North America as early as 1604. Ive been collecting almancs, books, diaries of early observations made in North America.The observation made on that record day in Winsdor was by a observer of course.Its very easy to click on your internet key board and access the Canadian Climate Data and find your answer but records go back in time like i said till 1604 which i have and took me 25 years and still today im researching this wonderful hobby which i love..Just a quick note on that day Toronto also set the record for January but further research could be done to see what is the all time record for Toronto and Windsor for January.Also the all time record that i have in my research for Montreal for JANUARY (Isle Jesus Observatory) at 6 am documented by Prof.Charles Smallwoods is -43.6 f or -42c. This cold arctic airmass in 1859 Jan 10 was by far the most brutal in terms of cold in the area.You could also go by the present recod for Windsor of -29.1 set in 1994 which is fine.But since records go back even further why not use them since they were made by observers just like you and me. Im sorry if i cannot write this in french but i speak french very well. Merci !!

En cette date 21 Janvier 1812 a Montreal la temperature chute a -33c .

correction !! Le record de froid absolu pour Windsor est de -30.0C le 10 janvier 1859... et non -29.1C en 1994.

En cette date 20 Janvier 1805 Montreal a recu 30 cm de neige avec des temperatures de - 20c et -30c .

2. The double-barreled storm system moving up toward eastern Canada later Thursday and then into Friday will not be a major storm, as the two systems (one moving over the Grate Lakes and the other moving up along the East Coast) will be competing for energy, but they will have a fair amount of moisture to work with. This will also be a fairly mild storm from southwestern Ontario through the Maritimes as the cold air out ahead of the storms will be quickly exiting, so we are looking at a wet snow over southwestern Ontario and mostly rain later Friday over Nova Scotia and PEI with the winds shifting into the southeast. 3. Behind this mess comes the Arctic cold front into southern Ontario Saturday. Behind the front some of the coldest air of the season will be coming down directly from the polar regions. There could be some decent lake-effect snow in the typical snow belt areas between Owen Sound and London, Ontario later Saturday and into Sunday, with much less off of Georgian Bay. 4. Sunday is going to be bitterly cold across all of eastern Canada, and with the wind staying up it is going to be nasty! The worst of the cold moves into Atlantic Canada Monday and Tuesday. alors je mise entre 8 cm et 12 cm avec ce type the mini tempete.

A Cold Spell is coming, says Russian Scientist Dr. Oleg Sorokhtin, a Merited Scientist of Russia and fellow of the Russian Academy of Natural Sciences says that Earth is now at the peak of one of its passing warm spells, which according to him, is a natural process and utterly independent of hothouse gases. According to Sorokhtin's article from the Russian News and Information Agency, data obtained from Habibullah Abdusamatov, who is the head of the Pulkovo Observatory space research laboratory, shows that a fairly cold spell will set in quite soon, by 2012, but real cold will come when solar activity reaches its minimum, by 2041, and will last for 50-60 years or longer. Sorokhtin also notes..... Carbon dioxide is not to blame for global climate change. Solar activity is many times more powerful than the energy produced by the whole of humankind. Manâs influence on nature is a drop in the ocean. Earth is unlikely to ever face a temperature disaster. The principal is Earthâs reflective power, which regulates its temperature. A warm period, as the present, increases oceanic evaporation to produce a great amount of clouds, which filter solar radiation and so bring heat down. Things take the contrary turn in a cold period. alors quel que chose a penser ???
