A good question. What you are basically asking and which has not been answered is the meteorological conditions under which these storms may form. As an Air Force meteorologist for many years I use to watch the forecasters who specialized in this kind of forecasting in Omaha, Nebraska as they worked. What they looked for was a region where warm, moist, unstable surface air coming from the south with drier, stronger, westerly air overlaying it may exist. The other thing they looked for would be the possibility of thunderstorm development or movement of thunderstorms into that same region. Where these two met and the wind shear from near the surface to cloud level was such that the thunderstorms would experience a cyclonic circulation it would be anticipated that a tornado vortex may develop. One of the major differences between this phenomena and other cyclones such as extra-tropical low pressure centers found along frontal zones, or tropical cyclones that develop into hurricanes is primarily size. The tornado cyclone is often on the scale of hundreds of meters or less. Other significant differences include a far deeper pressure, and extremely higher winds.

Storm is any disturbed state of an astronomical body's atmosphere, especially affecting its surface, and strongly implying severe weather. It may be marked by strong wind (a wind storm), thunder and lightning (a thunderstorm), heavy precipitation, such as ice (ice storm), or wind transporting some substance through the atmosphere (as in a dust storm, snowstorm, hailstorm, etc).

Storms are created when a center of low pressure develops, with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds, such as the cumulonimbus. Small, localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds

=======================================================

A tornado is a violently rotating column of air which is in contact with both a cumulonimbus (or, in rare cases, cumulus) cloud base and the surface of the earth. Tornadoes can come in many shapes, but are typically in the form of a visible condensation funnel, with the narrow end touching the earth. Often, a cloud of debris encircles the lower portion of the funnel.

Most tornadoes have winds of 110 mph (175 km/h) or less, are approximately 250 feet (75 meters) across, and travel a few miles (several kilometers) before dissipating. However, some tornadoes can have winds of more than 300 mph (480 km/h), be more than a mile (1.6 km) across, and stay on the ground for dozens of miles (more than 100 kilometers).

tornados suck instead of blow as do other storms.
