That is not true. A number of long lived and very destructive tornadoes have occurred near or even crossed bodies of water.
It depends on the tornado. In most tornadoes the strongest winds are near the center. In multivortex tornadoes, however, the strongest winds are in the subvorticies, which are almost like smaller tornadoes within a larger one.
There is no evidence of a relationship between tornadoes and wind farms. However, wind farms are often built on open plains, and the central plains of the U.S. are a tornado prone region.
A tornado gets its energy from the the thunderstorm that produces it. Most tornadoes are a product of thunderstorms with strong, rotating updrafts. These rotating updrafts get their energy from a combination of water vapor and wind shear. The water vapor is the main fuel of the storm. Thunderstorms work by drawing warm, moist air upwards from near the ground. As the air rises it cools and the water vapor condenses, releasing huge amounts of energy in the process. The wind shear, meaning difference in wind speed and direction with altitude, gives a storm the spin it needs to produce tornadoes.
When you put water near a window after a couple days it will evaporate.
Tornadoes of any intensity can merge, however, it would be extremely unusual for two F5 tornadoes to be in such close proximity. The closest this came to happening in Kansas in 1990. As the Hesston, Kansas tornado was beginning to dissipate the tornado that would later hit Gossel, Kansas was forming. The two tornadoes neared each other and eventually the smaller Hesston tornado, which was in its "rope-out" stage was absorbed into the other, intensifying tornado. Although both tornadoes were ultimately rated F5, neither was at F5 intensity when the two twisters merged.
They can but it is not a requirement. In fact Kansas, which is 500 miles from the nearest ocean water, has one of the highest rates of tornadoes in the world.
Sorry, you cant.
There was recently a series of 67 tornadoes all produce by the same storm system lasting from October 23 to October 27. The last of these tornadoes was an EF1 that occurred near King, North Carolina. The strongest of these tornadoes was a strong EF2 (near EF3) that struck Rice, Texas on October 24.
It is not uncommon for larger tornadoes to last longer, but not always. For example, the first of two tornadoes near Happy, Texas on May 5, 2002 had an extremely larger funnel, but lasted only about 15 minutes, while other, smaller tornadoes have lasted for over an hour.
It is possible, tornadoes have touched down near Kimberly before.
Tornadoes are not a common occurrence near the equator, however, waterspouts, which occasionally come on land an become tornadoes may still occur. Near the equator such tornadoes probably spin clockwise and counterclockwise in equal numbers.
As of May 13, 2015 the last tornado to hit Texas this month was the second of two EF0 tornadoes near Jefferson on the night of May 10. It was at least four tornadoes to hit Texas on that day. This will likely not be the last tornado to hit Texas in May 2015.
Yes, there are tornadoes in and near the Appalachian Plateau. There was one incident in 1994.
No, hail doesn't fall in tornadoes, but it often falls near them.
Smaller tornadoes near a larger tornadoes are often called satellite tornadoes. Smaller vortices within a tornado are called subvorticies or suction vorticies.
As of January 17, 2013 the last tornado in the U.S. was an EF1 near Poplarville, Mississippi on January 13. It was one of four weak tornadoes to occur in the southern U.s. that day.
As of October 13, 2014 the last known tornado was on October 10 near Centerville, Tennessee. it was rated EF1. More tornadoes are expected today.
