Oddly, the highest concentration of tornado reports in Canada is actually in southern Ontario, just north of Lake Erie. This, however is due to the high population density, which means that tornadoes are more likely to be reported whent hey do occur. Significant tornadoes are more common in Manitoba, Alberta, and Saskatchewan as they experience some of the same effects that have led to the high incidence of tornadoes in Tornado Alley to the south. Some even consider southern Manitoba to be part of Tornado Alley.
In this region it is not uncommon to have collisions of warm, moist air from the Gulf of Mexico, cool air from northern Canada, and dry air from the Rockies. These collisions result in very strong thunderstorms, with the moist air acting as their "fuel." Additionally, the region often has a layer of stable air called a cap that suppresses storms. This behaves like the lid on a pressure cooker, allowing the atmosphere below it to become increasingly unstable until storms develop explosively. Finally, the region often sees strong vertical wind shear, or a variation of wind speed and direction with altitude. This tilts them in such a way that the updraft and downdraft portions becomes separated and don't interfere with one another, letting the already strong storm further strengthen and last longer. The wind shear also sets the storms rotating, turning them into supercells, the most powerful thunderstorms on earth. It is the rotation within these supercells that can develop into a tornado.
What else can I help you with?
What ways do tornadoes?
Tornadoes usually rotate clockwise in the southern hemisphere, and anti-clockwise in the northern hemispere. This is called cyclonic rotation. Very rarely, a tornado will rotate anticylonically. Does this answer your question?
Where do tornadoes normally hit in AL?
Tornadoes are more common in the northern half of Alabama than in the southern part, though the whole state is pretty prone to tornadoes.
What direction do tornadoes rotate in the northern hemishpere?
The vast majority of tornadoes in the northern hemisphere rotate counterclockwise.
Does wind blow clockwise in the nirthern hemesphere?
Very rarely. Most tornadoes in the northern hemisphere, over 99%, spin counterclockwise. A very small percentage of tornadoes in the northern hemisphere, called anticyclonic tornadoes, spin clockwise. Most tornadoes in the southern hemisphere spin clockwise.
What area in AK has the least tornadoes?
Northern Alaska has the fewest tornadoes, likely none at all. Only 4 tornadoes have ever been recorded in the state's history, and all were in the southern part.
Does Seattle WA get tornadoes?
It can, but very rarely.
In what region do tornadoes occur most in Gerorgia?
Tornadoes in Georgia are most common in the northern and central regions of the state. Areas like the northern Atlanta suburbs and the central region around Macon tend to experience a higher frequency of tornadoes compared to other parts of Georgia.
What area of Texas gets tornadoes?
Well, there is one place I know of that has really never seen a tornado. That is Dallas, Texas.
When will most tornadoes occur in the northern states?
The northern states get the most tornadoes in late spring and summer.
Do most tornadoes in the northern hemisphere rotate in a clockwise or a counterclockwise direction?
Most tornadoes in the northern hemisphere, at least 99%, rotate counterclockwise.
Where Do tornadoes happen Texas?
Tornadoes can happen anywhere in Texas, but they are most commonly observed in the central and northern parts of the state, particularly during the spring months. This region, known as Tornado Alley, experiences a higher frequency of tornadoes due to the clash of warm, moist air from the Gulf of Mexico with cold, dry air from the Rocky Mountains.
Which way do cyclones and tornadoes blow in the northern hemisphere?
Cyclones spin counterclockwise in the northern hemisphere.
