Tornadoes

The fire tornado happened in Brazil august 25th of 2010

Yes, tornadoes can occur in Toronto, although they are relatively rare. Toronto is in an area that is at risk for tornadoes, but they typically do not happen as frequently or with the same intensity as in other regions, such as the central United States.

On average, South Dakota experiences around 30 tornadoes per year. These tornadoes can range from weak to strong in intensity and typically occur during the spring and summer months. Tornadoes in South Dakota are also more common in the eastern part of the state.

A portable Doppler radar is a small Doppler radar mounted on the back of a truck.

These radars use radio waves to capture detailed close-range images of conditions and structures inside tornadoes and other storms.

Yes, Odessa, Texas is considered to be part of Tornado Alley, a region in the central United States known for frequent tornado activity. The city may experience higher risks of tornadoes compared to other areas.

Not exactly. Most experts will say that during tornado, the wind will bend a tree significantly, which can open up cracks in the windward side. Small objects carried by the wind can then get blown into the cracks and become stuck when the tree bends back to its usual shape.

The process of tornado formation starts when rolling air called wind shear gets taken into the updraft of a thunderstorm. This turns the storm into a supercell, a storm with a strong, rotating updraft called a mesocyclone. Under the right conditions a downdraft can descend from the back of the storm, wrap around the mesocyclone, and force it into a tighter more intense vortex: the tornado itself.

Visible signs of a possible tornado often start as rotation in the clouds of a severe thunderstorm, often with a lowered section of the cloud base called a wall cloud. As this happens a cloud of dust may appear near the ground as something called a rear-flank downdraft wraps around the rotation.

Then a cone, funnel or elephant trunk shaped projection may lower itself from the cloud base. A cloud of dust and debris under this funnel cloud usually means that the tornado has touched down.

First we need to figure out what we mean by "mini tornado", as the term has no definition.

Some European and Australian news outlets refer to the tornadoes they get as "mini tornadoes" regardless of how large or strong they are. These form in the same manner as any tornado.

Some people might use the term "mini tornado" to refer to any tornado that is comparatively small and weak. These form in the same way strong tornadoes do, but with less ideal conditions. Weak tornadoes and waterspouts can form in a couple other ways as well.

Finally, sometimes small whirlwinds such as dust devils are sometimes called "mini tornadoes." These are not actual tornadoes and have their own ways of forming.

As to formation:

The classic means of tornado formation is through a kind of thunderstorm called a supercell. Supercells typically form along a cold front or dry line, at the edge of or just inside a warm, humid air mass. The storms are fueled by the warm, moist air and rotate due to interactions with a condition called wind shear, where wind speed and direction changes with altitude. The area of rotation in these storms is called a mesocyclone. Under the right conditions a downdraft can wrap around the mesocyclone, tightening and intensifying it into a tornado. Mesocyclones can sometimes be embedded in a squall line as well.

Sometimes "spin up" tornadoes can form along the turbulent leading edge of a severe squall line. These tornadoes are generally short-lived and weak. There is yet another kind of tornado called a landspout. These form when there is a broad circulation of air at ground level that gets caught in the updraft of a developing thunderstorm, which stretches and tightens it into an intense vortex. Waterspouts form in a similar way.

Finally we have other whirlwinds that are not considered tornadoes, but look a bit like them. Dust devils are the most common example. These form on days when the sun heats a patch of ground, creating a layer of extra hot air right at ground level. This will rise up in a thermal. Sometimes this updraft will catch an eddy in the wind, causing it to tighten and intensify, lifting dust and sand into the air. People have also observed things such as "haydevils" which are essentially the same thing. Finally there are the whirls that pop up on windy days. These are simply eddies that form from the wind going around things such as buildings and trees. They sometimes can be seen when they pick up snow, leaves, or other light materials.

Tornadoes can occur in Clearwater Beach, Florida, as the state is prone to experiencing tornadoes. However, tornadoes in this area are less common compared to other regions like the Midwest. It's still important for residents and visitors to stay informed about weather alerts and have a plan in case of severe weather.

One is a violently rotating column of air and debris that can tear a path of destruction over a mile wide with wind speeds well over 200 mph. The other is a well known brand of vacuum cleaner and vacuum cleaner accessories. Check out their homepage at the related link; they have some fantastic online sales at times.

A tornado possibly formed in southern Indiana on April 3, 2003. The National Weather Service conducted a survey and determined that there was a tornado in the area, but the evidence was not definitive.

There is no scientific evidence to support the idea that a tornado won't form where two rivers converge. Tornadoes can occur anywhere under the right atmospheric conditions, and rivers do not have a significant influence on their formation or path.

The last confirmed tornado in Junction City, Kansas was on June 30, 1993.

Yes, tornadoes can occur in Edmonton, although they are relatively rare compared to other regions in Alberta. Tornadoes in this area are typically weaker and less frequent compared to tornado-prone areas in the United States.

Cumulonimbus clouds produce thunderstorms and can also spawn tornadoes under the right conditions. These clouds are characterized by their towering height and anvil shape, and they are associated with severe weather events due to their ability to generate strong updrafts and downdrafts.

In most cases an F1 tornado does not have that much energy and soon runs out and is more easily disrupted, though a few F1 tornadoes have had long damage paths.

By contrast an F5 tornado will generally have several orders of magnitude more energy to release. Additionally, such a strong tornado could be considered more robust. A shift in the parent storm that might cut can F1 tornado's lifespan and thus damage path short, while the same shift might only weaken an F5 tornado somewhat.

A rainbow twister, also known as a rainbow tornado, is a rare and unlikely weather phenomenon. The conditions required for both a tornado and the presence of sunlight to create a rainbow are difficult to occur simultaneously. While not impossible, the chances of witnessing a rainbow twister are extremely low.

Here are the wind estimates for the Fujita scale categories

F0: 40-72 mph

F1: 73-112 mph

F2: 113-157 mph

F3: 158-206 mph

F4: 207-261 mph

F5: 261-318 mph

F6: 319-379 mph

Note that the F6 category is entirely theoretical and is not actually used in practice. Since actual ratings are based on damage, and since F5 damage is complete destruction, no tornado can ever be rated higher than F5.

These wind speeds are estimates meant to correspond with different damage levels that have since been found to be inaccurate. They have since been corrected as follows:

EF0: 65-85 mph

EF1: 86-110 mph

EF2: 111-135 mph

EF3: 136-165 mph

EF4: 166-200 mph

EF5: over 200 mph.

While the wind speed estimates have been adjusted for each category, the degree of damage remains the same.

The panhandle region in the western part of Oklahoma typically experiences the fewest tornadoes in the state. This area's drier climate and lower population density contribute to fewer tornado occurrences compared to other regions in Oklahoma.

Yes, Indiana is considered to be within the area known as "Tornado Alley." Tornado Alley is a region in the central United States, where tornadoes are more frequent due to the clash of warm, moist air from the Gulf of Mexico and cooler, drier air from the Rockies and Canada.

The tornado's direction of movement is northwest at a speed of 30 miles per hour. This information helps to track and predict its path and potential impact on the area. It is important to take immediate safety precautions in response to the tornado warning.

By how strong the tornado is.

Even though strong tornadoes tend to be larger how strong a tornado is does not determine its size.

Relatively weak tornadoes have been very large and extremely strong tornadoes have been relatively small.
