Tornadoes vs. Hurricanes

A tornado is a violently rotating column of air that extends from a thunderstorm cloud to the earth’s surface. The winds in the tornadoes are usually 100mph or less. They usually stay on a track of a few miles or less and are less than 100 yards wide.

For the development of tornadoes there are a few conditions required. An abundant low-level of moisture and unstable atmosphere is required not only for the tornado, but for a thunderstorm also. A “trigger”, which is a cold front or low-level zone of converging winds, is needed to lift the moisture and the air. When the air rises, it becomes saturated and continues to rise higher and higher. They then form in areas where winds at all levels of the atmosphere are strong and turn clockwise with height. Some tornadoes appear as a funnel shape and some have a churning smoky look.

Tornadoes can occur at any time of the year, and anywhere in the world. The super outbreak is one of the most infamous events that occurred in 1974. It was one of the most violent tornado events ever on record in the United States .The 1974 Super Outbreak spawned 148 tornadoes, the largest number of tornadoes eve


A natural hazard is when extreme events which cause great loss of life and or property and create severe disruption to human lives, such as a hurricane. Most hurricanes originate within the doldrums, a narrow equatorial belt characterized by intermittent calms, light variable breezes, and frequent squalls, and lying between the northeast and southeast trade winds. As the doldrums of the Atlantic are situated largely to the north of the equator, hurricanes do not occur in the South Atlantic Ocean. The Pacific doldrums extend north and south of the equator; thus hurricanes occur in the South and North Pacific oceans.

Since 1943 U.S. military aircraft have been flying into hurricanes to measure wind velocities and directions, the location and size of the eye, the pressures within the storms, and their thermal structure. A coordinated system of tracking hurricanes was developed in the mid-1950s, and periodic improvements have been made over the years. Radar, sea-based recording devices, geosynchronous weather satellites, and other devices now supply data to the National Hurricane Center in Florida, which follows each storm virtually from the
