S.". This helped them to correct for population bias. For more tornado safety tips, please visit: http://www.theweathernetwork.com/news/articles/tornado-safety-tips/9366/. Some people include parts of Minnesota and Wisconsin, as well. Bluestein says that when winds from the west become superimposed over winds from the south, it can result in a change of wind direction and speed, which is called wind shear. Based on these findings, a tornado-prone map was created and then published in the National Building Code – 2011. 6 Incredible Canadian Tornadoes. Canada's 'Tornado Alley' runs through Windsor and Essex County. The team was able to map every confirmed or probable tornado from 1980 through 2009 as shown below. Tornado-related research has also been undertaken in the science of structural engineering. Tornado Alley: a region of the United States where we find the highest frequency of tornadoes. The new EF-scale is similar to the original F-scale but with more accurate matches between wind speeds and tornado-caused damage. Prone to Significant Tornadoes – Probability of an F2 – F5 tornado is estimated to exceed 10-5/km2/year. So as summer severe weather season approaches for Canadians, we want to keep you prepared. If you mention Oklahoma, you can’t help but recall the devastating tornadoes that have torn through Moore, Oklahoma on several occasions. "One of the keys for us is getting a better database of historical events – how many [tornadoes] were we getting in the early part of the 20th century, how many are we getting now. Most tornadoes in Canada occur in southern Quebec, Ontario, Manitoba, and most of Alberta, New Brunswick, Prince Edward Island, and Saskatchewan, as well as in the center of British Columbia around the Okanagan Valley. Oklahoma is particularly vulnerable to tornadoes, lying inside the so-called 'Tornado Alley', stretching from South Dakota to Central Texas. Sills explains: “Environment Canada research on tornadoes is related to developing new climatological data based on verified tornadoes, and investigating statistical approaches that adjust observed tornado data in order to compensate for population bias.”. The look of a tornado does not always dictate its strength and the amount of damage it can do. (At the end of this there is a section on tornado safety. Below is a chart demonstrating the old F-scale versus the Canadian implementation of the EF-scale. Storm chasing is a team game and we need all hands on deck.

Tornado Alley (PROG) Message Board: Canada Seeks Alternatives to Transport Oil Reserves They used this dataset to help model tornado incidence. What this means for Canadians is more tornado-resilient construction on new homes in the at-risk regions. But it looks like the region had something of a reprieve this season, boasting May and June tornado numbers lower than they've been for half a century or more, with the U.S. National Weather Service (NWS) going so far as to call it a tornado drought. It is also important to have a plan in place and know where your safe spot is or what to do should you be faced with a tornado threat. Environment Canada, however, is still investigating the correlation between climate change and severe weather. Tornado Alley is prone to tornadoes because, in this region, cold, dry air from Canada and the Rocky Mountains meets warm, moist air from the Gulf of Mexico and hot, dry air from the Sonoran Desert. Underground, basement or interior room will be the safest places with as many walls between yourself and the outside as possible (preferably windowless). Based on knowledge of structural engineering, and based on a damage assessment, scientists are able to estimate the range of winds that needed to be present at the time of the tornado to cause the damage observed. Box 500 Station A Toronto, ON Canada, M5W 1E6. For the weather-savvy individual, this might not come as a huge surprise but it is clear that tornadoes are a real threat to many Canadians. It’s a relatively small effect, but in the situation where you’ve already got strong storms from natural [weather] variability, adding a little bit more means you can break records," he says. Note Canada's only F5 tornado occurred in Manitoba. In the two tornado events experienced in the capital there have been zero fatalities. "There are a couple of areas that we look at as being very active for tornadoes, as well as other forms of summer severe weather," says Coulson. But while the Prairies are known as the centre of tornado activity in the country, The Weather Network reports that another area of the country is also situated at the confluence of meteorological conditions that produce twisters. Source: *Ongoing* research, Environment Canada (Sills et al). The other is the southern prairies, extending from Alberta to Manitoba. There is a sharp rise in activity from April to May then a decline into October with July peaking in activity in the middle. Meteorologists know the ingredients necessary to create environments conducive to tornado formation but the exact trigger, the final ingredient that ultimately kicks off ‘tornadogenesis’, is not known but there are many theories as to what it might be. “We also worked with wind engineers at Western University in London to increase our knowledge of the relationships between wind damage and wind speed, to be used to improve the Enhanced Fujita Scale for wind damage rating,” Sills describes. The first is that the area is downstream of the Gulf of Mexico, which is a source of warm, moist air. The tornado in Oklahoma, which generated winds as strong as 320 km/h and was classified an EF-4 on the enhanced Fujita scale, fell in a geographical area of the U.S. generally known as "Tornado Alley.". ... with Canada ranking second at only 100 per year. This region is known as “Canada’s Tornado Alley," or more accurately, as Canada’s “Prone to Significant Tornado" region. Tornadoes per year per province and nationally.

Energy from climate change has increased the temperature of the oceans by about one degree Fahrenheit over the last 30 to 40 years, and as a result, there’s about a four- to five-per-cent increase in the amount of water vapour over the oceans, says Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research in Boulder, Colo. Tornadoes like the one in Oklahoma effectively begin with moisture coming from the Gulf of Mexico, and any additional vapour will likely affect their severity, says Trenberth. Tornadoes come in all shapes and sizes -- from wide and menacing looking (see below) to thin and wispy. In 1971, severe storm researcher Tetsuya (Ted) Fujita, of the University of Chicago, and Allen Pearson, then head of the National Severe Storms Forecast Center, collaborated on developing a scale that would rate tornadoes based on the damage they did to structures and vegetation. When asked what one of the biggest revelations was upon working on this research, Sills mentions that it was interesting and impressive to him that. Within those areas, southern Saskatchewan and Manitoba – south of a line from roughly Saskatoon to Winnipeg – and the part of southern Ontario between the Great Lakes from roughly Windsor to Barrie are the two most active tornado corridors [in Canada].”. The reason the Canadian prairies are vulnerable to tornadoes is that they get much of the warm, moist air working its way up from the American Deep South, which then combines with the drier air from the Rockies, says Coulson. Source: Environment Canada.

FICTION: Objects such as rivers, lakes or mountains can protect certain areas from tornadoes. They combined this lightning flash density climatology with a population density mask. Intense lightning bolts, five times hotter than the sun, emerge from the underbelly of storms complemented by exceedingly loud thunder that rattles windows and deafens ears. Google "Tornado Alley"-- you typically get maps that are restricted to the US, such as the one at the left. Of course there can’t be a DOW present for every tornado that occurs so only a very small fraction of tornadoes that occur in the United States get their wind speeds measured via this method.

"Tornado Alley is a colloquial expression, there’s no formal definition of it," says Howard Bluestein, professor of meteorology at the University of Oklahoma. Sills, D., V. Cheng, P. McCarthy, B. Rousseau, J. Waller, L. Elliott, J. Klaassen and H. Auld, 2012: Using tornado, lightning and population data to identify tornado prone areas in Canada. Tornado Alley is a nickname given to an area in the southern plains of the central United States that consistently experiences a high frequency of tornadoes each year. “There are some rural and/or remote areas of Canada where we get very little in the way of tornado reports, but we know that intense thunderstorms capable of producing tornadoes regularly occur there,” explains Sills. Another interesting outcome of the research was that these results, the mapped tornado-prone areas, have activated certain measures in the National Building Code of Canada. Although the real Tornado Alley is in the United States, where more than 1,200 tornados occur each year, Southwestern Ontario and the southern prairies have the highest levels of tornado activity in Canada, said Kimbell. One is in southern Ontario stretching from Windsor up through London to Barrie, Coulson says. For example, a great number of people would report a tornado if it occurred near the Greater Toronto Area where maybe only a couple of people would report a tornado in a rural area north of Regina compared to no one reporting a tornado that occurred in the forests of northern Ontario.
