How does latent heat help create thunderstorms?

'Latent heat' means heat that is absorbed but does not result in a temperature increase. A good example of latent heat is boiling of water:

H2O(l) + heat = H2O(g)

However, the temperature remains at 100 deg C while water is boiling, so that the heat being consumed is used to vaporize water and not to increase the temperature of the liquid.

Latent heat can be added to the atmosphere by evaporation of water. Since a water molecule contains more heat at a given temperature than an air (N2 and O2) molecule, its presence increases the heat content of the air without changing the temperature.

How big is an F4 tornado?

An F4 tornado is classified as an intense tornado with wind speeds between 207-260 mph. The damage it can cause is devastating, often leveling well-constructed houses and sending cars flying through the air. The path of destruction can be several miles long and a mile wide.

Can tornadoes go downhill?

Tornadoes typically move in the direction of the prevailing winds, but they can also change direction due to the local terrain. Tornadoes can move downhill if the conditions are right, but it is not common.

Who discovered tornadoes?

There are a lot of people who study tornadoes such as storm spotters and storm chasers as well as tons of meteorologists. The National Weather Service are the main people who study tornadoes along with the different centers located within the National Weather Service such as the Severe Storms Laboratory, and the Storm Prediction Center. They do it to gain a better understanding of tornadoes and their inner workings to try and create better technology which could help save more lives.

How many kilometres can a tornado travel?

It varies widely. Some tornadoes travel less than a kilometer. A typical path might by 5 to 10 kilometers. Not very many tornadoes will travel more than 50 kilometers, however there are extreme cases. A handful of tornadoes have been recorded with paths over 300 kilometers long, with the record path length being 352 kilometers.

Are Georgia and Oklahoma in Tornado Alley?

Yes, Georgia is not typically considered part of Tornado Alley, which is a region in the central United States known for frequent tornado activity. However, Oklahoma is often included in Tornado Alley due to its high concentration of tornadoes and severe weather conditions.

What are the conditions of a thunderstorm?

Thunderstorms are characterized by the presence of cumulonimbus clouds, which are large, towering clouds that indicate the potential for heavy rain, lightning, thunder, and strong winds. Thunderstorms require warm, moist air near the ground and instability in the atmosphere to form. Additionally, a trigger, such as a cold front or converging air masses, is often needed to initiate the development of a thunderstorm.

Where in the US can tornadoes happen?

Tornadoes have occurred in all 50 states. However. Most tornadoes happen in or near the area known as tornado alley, which extends north from Texas to South Dakota and includes parts of some adjacent states.

Do you run from tornadoes?

evacuating from a tornado is not advised. You are safest underground or inside a sturdy building. In one well-known case of people trying to flee a tornado 25 of the 42 deaths were in cars. Some of these people killed trying to flee left homes that the tornado never touched.

What happens if a tornado strikes the ground?

When a tornado strikes the ground, it can cause significant damage by tearing apart structures, uprooting trees, and tossing debris at high speeds. Tornadoes can create a path of destruction that is several miles long and can be up to a mile wide. It is important to take shelter immediately in a sturdy building or underground if a tornado is approaching.

How many tornadoes are reported nationwide in an average a year?

On average, the United States experiences about 1,250 tornadoes per year. This number can vary greatly depending on the year and the weather patterns. Tornadoes can occur in any state, but they are more common in certain regions known as "Tornado Alley."

What are some real life examples of tornadoes?

There is no shortage of examples, with more than 58,000 tornadoes confirmed in the U.S. since 1950. Here are a few from recent years that cover the range of tornado severity.

  • On February 28, 2012 a weak tornado touched down west of Greeley, Nebraska. It traveled for about a quarter of a mile through a field and overturned and irrigation pivot. The tornado was rated EF0, the lowest rating on the Enhanced Fuita Scale and had estimated winds of 75 mph. The cost of damage was $50,000.
  • On July 24, 2010 a tornado touched down south of Westfield, New York and move through Mayville, badly damaging several homes before crossing part of Lake Cuatauqua as a waterspout. It came ashore at Dewittville, damaging several small boats and a golf course where a number of golf carts were destroyed. One condo lost most of its roof. The tornado was rated EF2 with estimated winds of 125 mph. Damage was estimated at $5 million.
  • On January 30, 2013 a tornado touched town southwest of Adairsville, Georgia and moved through that town, destroying 31 sturectures and damaging dozens of others. One person died in a mobile home and several others were injured. The tornado continued into the next county, where it destroyed about 30 homes and damaged over 200. The tornado was rated a high-end EF3 with estimated winds of 165 mph. The cost of damage was estimated at $75 million.

What is the difference between a supercell and a non-supercell tornado?

A supercell tornado forms from the larger circulation of the mesocyclone, which is a rotating updraft within a supercell that is a few miles across and has a measurable pressure deficit. Strong tornadoes are almost always supercell tornadoes.

Non-supercell tornadoes form in the absence of a preexisting mesocyclone and instead form from the interaction of localized twisting in the air at low levels with the updraft of a thunderstorm. Such tornadoes are typically referred to as landspouts. They are generally weaker than supercell tornadoes, rarely exceeding EF1 intensity.
