It's the same force that lifts an airplane off the ground. When air has to take a longer route around an object to get to the other side it is kind of "stretched" or "thinned out" (Bernoulli effect) so its pressure is lowered which gives it a "suction" property.

What kind of destruction can a tornado do from the strength and size?
The size of a tornado does not necessarily relate to the destruction it causes. While a large tornado can case damage over a larger area, the damage is not necessarily more severe. However, larger tornadoes do tend to be stronger and thus more destructive. The intensity of a tornado can be assessed based on the severity of the damage it causes. The most severe damage a tornado causes is used to assign a rating on the Enhanced Fujita Scale. Below are the levels on the scale with damage typically associated with that rating. Note that a tornado only needs to cause a small amount of a given type of damage to qualify for a rating. e.g. one house with EF3 damage is enough to rate a tornado EF3. EF0: 65-85 mph. Shingles peeled from roofs, fences blown down, tree limbs broken, weak trees toppled. Very weak structures such as sheds may be destroyed. EF1: 86-110 mph. Roofs of frame houses badly damaged. Windows broken, Trailers overturned and/or badly damaged. Barns destroyed. Poorly secured roofs may be torn off. EF2: 111-135 mph. Roofs torn from well built houses, trailers completely destroyed. Large trees snapped. Cars lifted and tossed. Poorly anchor structures may be shifted. EF3: 136-165 mph. Exterior and possibly interior walls collapsed in well built houses. Large vehicles lifted. Weaker houses and businesses may be leveled. Trees lifted into the air. EF4: 166-200 mph. Well built houses completely leveled. Houses with structural deficiencies swept away. Trees debarked. Asphalt peeled from roads. EF5: over 200 mph. Well built, well anchored houses wiped clean from foundations. Debris broken into small fragments. High rise buildings significantly deformed. Significant ground scouring may occur.
