Downbursts vs. Tornadoes
People often confused downbursts with tornadoes, here's a little information to try to clear up the differences. A downburst is an area of strong, often damaging winds produced by a convective downdraft over an area from less than 1 - 10km in horizontal dimensions. Its a strong down downdraft which includes an outburst of potentially damaging winds on or near the ground. Now a tornado is a violently rotating column of air extending from within a thundercloud down to ground level. Tornadoes vary in diameter from tens of meters to nearly 2 km (1 mi), with an average diameter of about 50 m (160 ft). Peak wind speeds can range from near 120 km/h (75 mph) to almost 500 km/h (300 mph).
