The thing is, it can't. Maybe billions of tornados could, but I highly doubt that will ever happen.
It's Jupiter that has the long lived storm, not Mars
Around the Long Beach area we don't have tornadoes often, but in 2010 we did get a tornado warning and amazingly it got up to a A1....I think.From: webkinzandMCR on Youtube! :D

The worst tornado to strike the United States was the Tri-State tornado of March 18, 1925. This F5 tornado tore a 219-mile-long path of destruction across parts of Missouri, Illinois, and Indiana, ravaging many towns and killing an estimated 695 people.
This qualifies as a high-risk outlook. A 30 percent tornado probability typically means that the Storm Prediction Center anticipates a major tornado outbreak with the potential for multiple long-track and violent tornadoes.
The time it takes for a tornado to destroy something can vary depending on the tornado's intensity, size, and the durability of the object. In many cases, a tornado can cause significant damage within seconds to minutes as it passes through an area.
Usually a tornado can't destroy an entire town. When it does happen in will involve a very large, very strong tornado striking a very small town. In cases like this the town in question would probably be destroyed in about 5 minutes or less. Beyond that most towns would be too large to be completely covered by a tornado.
On the traditional Fujita scale there is no such thing as an F9 tornado. On the TORRO scale used in Britain a T9 tornado is a very violent tornado equivalent to a strong F4 on the Fujita scale. Such a tornado will destroy most buildings in its path.
It varies depending on the structure and the intensity of a tornado. In most cases, though, it takes a matter of seconds, which is usually how long a structure is exposed to the strongest winds. One analysis of the fast-moving EF5 tornado that hit Smithville, Mississippi tornado of 2011 found that houses wiped clean off their foundations were exposed to the strongest winds of the tornado for less than 3 seconds.
The duration of a tornado can vary greatly, from a few seconds to several hours. On average, a tornado lasts for about 10 minutes. Tornado strength, size, and environmental conditions all play a role in determining how long a tornado will last.
The whole world.....
The deadliest tornado outbreak in U.S. history was the one which produced the Tri-State tornado on March 18, 1925. As a whole the outbreak killed 747 people, 695 in the devastating Tri-State tornado, the deadliest single tornado in U.S. history. The F5 tornado cut a 219 mile long damage path through 13 counties in Missouri, Illinois, and Indiana.
The worst tornado on record, the Daulatpur-Saturia tornado that hit Bangladesh on April 26, 1989 was definitely more severe than a typical tornado. This tornado killed 1,300 and left 80,000 homeless. The damage path was 50 miles long, compared with a mile or two for a typical tornado, and was probably much larger and stronger than a typical tornado as well, though no details on that information are available. A typical tornado does not kill and is not strong enough to destroy most homes, though it may be different in Bangladesh where many homes are poorly built.
The worst tornado in U.S. history, the Tri-State tornado of 1925, was on the ground for 3 hours and 29 minutes. The worst in world history, the Daulatput-Saturia tornado of 1989, had a path length of 50 miles but it is not known how long it was on the ground. However, given the path length it was probably on the ground for an hour to two hours.
The Great Natchez Tornado was a devastating tornado that struck Natchez, Mississippi, on May 6, 1840. It remains one of the deadliest tornadoes in U.S. history, killing at least 317 people and causing widespread destruction in the area. The tornado had a long track and reached estimated wind speeds of over 300 mph.
The longest tornado damage path on record is 219 miles.
until the tornado ends and then the people fall and die or get injured
