Tornadoes
A tornado or twister is a violent, rotating column of air which typically has a speed ranging from 177 km/h to over 480 km/h. This devastating windstorm is usually characterized by its funnel-shaped cloud that extends toward the ground.

What don't scientists know about tornadoes?
Scientists are still not sure how exactly a thunderstorm produces a tornado or why one storm will produce a tornado while another won't. They are still not sure what determines how strong or how large a tornado will be or how long it will last.
What separates the categories for hurricanes and tornadoes?
They are rated on different scales.
Tornadoes are rated on the Enhanced Fujita scale from EF0 to EF5based on a wind speed estimated taken from damage.
Wind estimates for EF scale ratings
EF0: 65-85 mph
EF1: 86-110 mph
EF2: 111-135 mph
EF3: 136-165 mph
EF4: 166-200 mph
EF5 over 200 mph
Hurricanes are rated on the Saffir-Simpson scale from category 1 tor category 5 based on direct wind measurement.
Wind ranges for the Saffir-Simpson scale:
Category 1: 74-95 mph
Category 2: 96-110 mph
Category 3: 111-130 mph
Category 4: 131-155 mph
Category 5: over 155 mph.
Explain very briefly how a dark cloud becomes a tornado?
When warm, moist air rises rapidly into a storm system, it can create a rotating column of air within a dark cloud. The rotation intensifies as strong winds at different altitudes cause the column to stretch vertically, forming a tornado.
How and where do tornadoes occur?
Tornadoes occur mainly in the United States, particularly in the middle part of the country, in the region of the Great Plains states known as Tornado Alley. But very severe outbreaks have occurred in Florida and the Gulf Coast, and around the Great Lakes.
Tornadoes can occur nearly anywhere that gets thunderstorms, which is anywhere in the world except Antarctica. They are rare in the Northern polar region as well. They are very prevalent in the 40 to 60 degree latitudes in both hemispheres. Tornadoes are more common in the United States, UK, and Australia.
Tornadoes may be spawned by tropical storms and cyclones when they make landfall. These are seldom as severe as those associated with supercells in the interior US.
The tornado that hit delhi in 1977-1978?
March 17-18, 1978
In the northern suburbs of New Delhi, near the University, 28 people were killed and 700 were injured by a tornado that cut a path 3 miles long and 50 yards wide
How many tornadoes were recorded in Lasalle County Illinois since 1950 to 2009?
From 1950 to 2009 there were 36 tornadoes recorded in Lasalle County, Illinois.
Where do natural disasters mostly occur?
They occur in all different places in the world. Some places are more prone to earthquakes, like Haiti, which recently suffered a big earthquake that killed and injured many. There was a hurricane in Kent, England in 1989! :)
Is a tornado living or nonliving?
A tornado is nonliving. It is a rapidly rotating column of air that forms during severe weather conditions, such as thunderstorms.
What state has the record for the greatest number of tornadoes?
Texas has had the most recorded tornadoes.
Where in America do tornadoes happen?
Tornadoes can occur in the central part of the United States, often referred to as "Tornado Alley." This region includes states such as Texas, Oklahoma, Kansas, and Nebraska, where the atmospheric conditions are conducive to the formation of tornadoes. Tornadoes can also occur in other parts of the country, such as the Southeast and Midwest.
Tornadoes produce very fast winds, but they do not necessarily move quickly. Some tornadoes may move at over 60 mph, while others barely move at all.
When a tornado passes over do people often hear a deafening roar from the winds?
Yes. A tornado often produces a loud roar from a combination of the wind and buildings and trees being torn apart. It is said to sound like a freight train.
What would it be like to be inside a tornado?
The eye of a hurricane is the axis about which the air rotates. It is a place of low wind and apparently, very peaceful, compared the the rest of the hurricane. The peace is short lived however. As the eye of the hurricane moves, that spot will once again be engulfed in the winds that cause destruction and injury.
Are there tornadoes in South Carolina?
Yes, tornadoes can and do occur in South Carolina. The state is part of Tornado Alley East, an area that experiences frequent tornado activity. It is important for residents to have a plan in place in case of tornado warnings.
Does Texas have a lot of hurricanes or tornadoes?
Texas experiences both hurricanes and tornadoes. The coastal regions are more prone to hurricanes due to their proximity to the Gulf of Mexico, while tornadoes can occur throughout the state, with a higher frequency in northern and eastern Texas.
How many tornado's happened in Wichita?
There have been multiple tornadoes reported in Wichita over the years, with some causing significant damage. The exact number of tornadoes that have occurred in Wichita varies from year to year.
What is the simple subject of A tornado's shape is like a funnel?
the noun that pronounce predicate. they used " e or ed"
Is the dark base of a tornado called the wall cloud?
No, the wall cloud is a lowered section of the cloud base from which a tornado or funnel cloud descends. The dark cloud at the base of a tornado is called the debris cloud.
Is there a high incidence of tornadoes in the Tennessee area?
Yes. Tennessee has some of the most violent tornadoes within the US. The state is in the Dixie Alley, which experiences the most violent, strongest, and fastest tornadoes in the US. The Tornado Valley is probably more well known, however, this area just experience more tornadoes, not necessarily more violent ones than the Dixie Valley.
How many tornadoes have there been in one year?
The number of tornadoes in a year can vary greatly. On average, the United States experiences about 1,000 tornadoes annually, but this number can be higher or lower depending on various factors such as weather patterns and climate conditions.
Is it safe to seek shelter under the stairs during a tornado?
Seeking shelter under the stairs during a tornado is generally not recommended as it may not provide adequate protection from flying debris and collapsing structures. It is safer to go to a specially designed storm shelter or a small interior room on the lowest floor of a sturdy building.
Can a waterspout go over land?
Yes, a waterspout can occasionally move over land if it forms over a body of water and then moves inland. As it moves over land, it is known as a tornado rather than a waterspout. Waterspouts are essentially tornadoes over water.
Does a hurricane or a tornado have the lowest pressure?
Some of the lowest atmospheric pressures ever recorded at ground level or sea level were recorded in tornadoes and hurricanes. The lowest sea level pressure recorded at any United States-certified observing station was 892 millibars (26.34"), recorded at Matecumbe Key, Florida on September 2, 1935 in the "Labor Day Hurricane". The world record goes to Typhoon Tip when, on August of 1979, it recorded a central pressure of 870 millibars (25.69").
It is not known how low pressure in a tornado can get because very few measurements have been actually taken from inside a tornado.
The lowest pressure recorded in a tornado was approximately 688 millibars in Tulia, Texas on April 21, 2007.
However, this was not a sea level measurement and would likely have been higher if the tornado had occurred at sea level.
Are hurricanes and tornadoes related to each other?
Hurricanes and tornadoes are both types of storms, but they form under different conditions and have distinct characteristics. Hurricanes are large, organized systems that form over warm tropical waters, while tornadoes are smaller, localized systems that develop in thunderstorms. Both can cause significant damage, but they are not directly related to each other in terms of formation or behavior.
