What two air masses cause tornadoes? Tornadoes are most commonly found along cold fronts, which involve a cold air mass pushing into a warm air mass. However, not all tornadoes form along cold fronts and not all … cold fronts result in tornadoes. The factors in producing tornadoes are far more complex than simple air mass collisions.

What Causes Tornadoes? What Causes Tornadoes? A tornado is a rotating column of air extending from a thunderstorm to the ground. Tornadoes are capable of 250 MPH wind speeds, cutting a swath of destruction in excess of one mile width and dozens of miles in length. If you see a dark, greenish sky or a wall cloud and hail, you might be getting a tornado.

Severe Weather 101 An example of wind shear that can eventually create a tornado is when winds at ground level, often slowed down by friction with the earth's surface, come from the southwest at 5 mph. But higher up, at 5000 feet above the same location, the winds are blowing from the southeast at 25 mph!

What two air masses cause tornadoes? Tornadoes most often form where cool dry air and warm moist air collide. This does not directly produce tornadoes but rather produces the thunderstorms that, given a few other factors, can sometimes produce tornadoes. Additionally, such a meeting of air masses is not absolutely necessary for tornadoes to form. Tornadoes most often form where cool dry air and warm moist air collide. This does not directly produce tornadoes but rather produces the thunderstorms that, given a few other factors, can sometimes produce tornadoes.

What weather conditions are most likely to cause thunderstorm and tornado ? Rating Newest Oldest. Best Answer: The most basic conditions to produce thunderstorms and tornadoes are cold dry air and warm moist air. The warm air rises through the cold air and forms clouds. The stronger the differences between air masses; the more likely that a thunderstorm will form. However, when the air masses are very different, super cell thunderstorms occur and can produce tornadoes. http://en.wikipedia.org/wiki/Thunderstor... http://www.nssl.noaa.gov/edu/safety/torn...

Where Tornadoes Happen The land is very flat. The area experiences very unstable atmospheric conditions that can lead to the development of supercell thunderstorms. This region of the U.S. is known for dry, cool surface air temperatures. The Great Plains are conducive to the type of thunderstorms (supercells) that spawn tornadoes.

Air masses and fronts An air mass that developed in a source region over a large body of tropical water would be labeled mT (water, warm). An air mass that developed in a source region over an arctic land-mass would be labeled cA (land, cold). Air masses create weather as they are moved by winds around the globe.

What Causes a Tornado to Form? An area where the winds are blowing strongly in different directions creates a distinctive hook echo on the radar. This can quickly form the rotation necessary to suck warm, moist air up into the upper layers of the storm, creating the energy necessary to turn the rotation into a mesocyclone and then a tornado.

Severe Weather Glossary Cyclic supercells are capable of producing multiple tornadoes (i.e., a tornado family) and/or several bursts of severe weather. Debris Cloud - A rotating cloud of dust or debris, near or on the ground, often appearing beneath a condensation funnel and surrounding the base of a tornado. This term is similar to dust whirl, although the latter typically refers to a circulation which contains dust but not necessarily any debris.

- Tornado alley. Click on the image to view the large version. The middle part of the United States is an area that has many tornadoes, particularly in the spring. This area is known as tornado alley. The reason is because it is an area where large cold air masses and large warm air masses collide. When these air masses crash into each other, it can cause thunderstorms and they can create tornadoes.

What Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale Tornadoes form from thunderstorm clouds, which form when warm, wet air rises very quickly. As it rises, the cool air condenses into a large cumulus cloud. Like adding fuel to a fire, more rising warm air builds the cloud larger and larger.

- When the temperature difference between the cold and warm air is large, thunderstorms and even tornadoes may form. The types of weather that are associated with a cold front are  thunderstorms that may become severe.After the front passes, the  temperatures become cooler and the weather becomes clear.ornadoes frequently form along cold fronts and dry lines.  Occasionally they may form along warm fronts. Some tornadoes form  from thunderstorms not associated with any fro … nts.

Where Tornadoes Happen Where Tornadoes Happen. Most tornadoes are found in the Great Plains of the central United States – an ideal environment for the formation of severe thunderstorms. In this area, known as Tornado Alley, storms are caused when dry cold air moving south from Canada meets warm moist air traveling north from the Gulf of Mexico. Tornadoes can form at any time of year, but most occur in the spring and summer months along with thunderstorms. May and June are usually the peak months for tornadoes. Which two states have the highest number of tornadoes per year per 10,000 sq miles?

How Tornadoes Work Tornadoes and Thunderstorms. ­Tornadoes don't just pop into existence -- they develop out of thunderstorms, where there's already a steady, upward flow of warm, low-pressure air to get things started. It's kind of like when a rock concert erupts into a riot. Conditions were already volatile; they merely escalated into something even more dangerous.

Whirlwind Major whirlwind. A major whirlwind (such as a tornado) is formed from supercell thunderstorms (the most powerful type of thunderstorm) or other powerful storms. When the storms start to spin, they react with other high altitude winds, causing a funnel to spin. A cloud forms over the funnel, making it visible.

Funnel clouds Cumulonimbus clouds are almost always the host cloud from which tuba form, meaning that heavy rain, hail, thunder and lightning can all be expected. If a funnel cloud does make contact with the ground and produce a tornado, very strong winds can be expected in the immediate vicinity of the vortex potentially causing severe damage.

Build a Fog Tornado Build a Fog Tornado. What creates the 'tornado' part is the air created by the fan, forcing said air out of the chamber while the air from the openings on the side, forces air into the chamber. The positioning of the ventilation is critical for creating this tornado-like effect. The fog comes from the dry ice. Problem:
