Tornadoes occur more. While an active year might see a few dozen hurricane-strength tropical cyclones in a year, the United States alone documents an averages of more than 1,200 tornadoes annually.
Overall, tornadoes are more dangerous. A hurricane is more likely to kill a significant number of people, but that is because a hurricane is much large, putting more people at risk. Tornadoes develop much more quickly than hurricanes. You can have several days warning with an approching hurricane.
Tornadoes occur more often. It would be unusual for there to be much more than a dozen hurricanes in a season. While the United States along averages more than 1,000 tornadoes each year.
A tornado can cause worse localized damage than a hurricane but overall a hurricane causes more damage because it affects a much bigger area.
In terms of intensity ratings EF0 tornadoes are the most common.
The most common rating for a tornado is EF0, accounting for almost 60% of tornadoes in the U.S. The higher the rating, the less often it occurs.
Hail most often occurs ahead of the tornado but it also frequently found in the hook of the storm, which wraps around behind and to the left of the tornado (with respect to its movement) in the northern hemisphere and to the right of it in the southern hemisphere.
Tornadoes are often, but not always preceded by heavy rain and hail. This hail can sometimes be very large.
This often occurs because a tornado is in the updraft portion or rear ha;f of a supercell thunderstorm, while most of the wind rain and hail is in the downdraft portion or front half.
This isn't quite true. A relatively weak tornado can destroy a trailer but when it might cause not more than roof damage to a stronger structure. To destroy a more substantial structure would require a strong tornado (at least an F3) which occurs far less often. So tornadoes don't hit trailer parks more often than they hit anywhere else, but when they do hit trailer parks they are more likely to cause major damage.
Tornadoes are usually accompanied by heavy rain and often accompanied by hail.
Yes, this occurs sometimes during tornado outbreaks.
Tornadoes can merge, but it is rare. Most often it occurs when one large tornado absorbs a smaller one.
Most often, hail may form because of the updraft that a storm will create. The attached links will give you more information on hail and tornadoes.
Generally not. The storms that produce tornado form more often along cold fronts than warm fronts. So more often the weather is hot before a tornado and cooler afterwards.
The most common rating for a tornado is EF0, accounting for almost 60% of tornadoes in the U.S. The higher the rating, the less often it occurs.
Often there is, though there is more often precipitation before a tornado. Whether or not their is depends on the structure of the storm system that produced the tornado.
They don't need to be any color in particular. Though they are often green. The clouds near a tornado and even the tornado itself may appear orange if it occurs near sunset. Clouds near a tornado can also be gray or black.
Hail most often occurs ahead of the tornado but it also frequently found in the hook of the storm, which wraps around behind and to the left of the tornado (with respect to its movement) in the northern hemisphere and to the right of it in the southern hemisphere.
A typical tornado lasts several hours, often more than 5 hours.
The average lead time for a tornado warning is 15 minutes. Sometimes you get more warning, sometimes less.
A tornado. Tornadoes usually occur on land anyway.
