Introduction

Tornado Development

The tornado is a meteorological phenomenon that occurs following an air rotation intensive and low horizontal extension, which extends from the base of a parent cloud, known as cumulonimbus. The base of this cloud is at altitudes below 2 Km and is characterized by great vertical development, where its peak reaches about 10 Km height to the surface of the ground or near it.

A tornado which is also known as twister or incorrectly a cyclone is a brutal, hazardous, revolving feature of air. Tornadoes have different shape and size. They are usually in the appearance of a noticeable concentration funnel, whose contracted closing stages touches the ground and is over and over again surrounded by a cloud of debris and powder. Tornadoes have been formed when the temperature and humidity assembles by the two masses. A tough upward movement of warmer air has been formed when the lower layers of atmosphere are uneven. Merely a little proportion of system builds up into the thin, brutal funnel of tornadoes.

Tornadoes are an outcome of an extremely huge thunderstorm. Cold air and warm air merge and the cold air go down since the temperate air rises. This warm air finally twists into a coil that forms a direct cloud. The tornado starts its trail of devastation when the sky turns a dreadfully dark green color; the tornado has been classified into three types which are waterspout, land spout and multiple vortexes. Waterspout is the most common type. Land spout's diameter can exceed its height. Multiple vortexes are a type of powerful tornado that can cause heavy damage (CHARLES, 2005).

Tornado Composition

The fireplace in the tornado is a cloud droplets consisting of water mixed with dust and debris particles, which originate in the bases of the clouds and descend to the surface. The dust and debris are abundant near the grounds due to existing low atmospheric pressure that helps circulate air into and ascend. Inside, the walls forming the eye of the tornado usually occur electrical shock. Some tornadoes are formed by a single fire, while others form a system of several chimneys. Some last a few seconds, others persist for ten minutes.

Times when Tornadoes Form

Tornadoes generally occur in the transition zone between the polar air masses and tropical, between 20 º and 50 º of latitude, on both sides of Ecuador, still rare at latitudes above 60 degrees, where the air contains no moisture and the temperature required for the formation of this phenomenon in the equatorial region, where the atmosphere instability is not necessary to develop a severe storm of such magnitude. While tornadoes can occur along most of the year, there is a seasonal variation that differs from the country and place, and its maximum occurrence during summer in the midlatitudes (Juan, 1993).

Tornadoes can arise at any time of day, most often during the evening between 2:00 pm and 8:00 pm, this situation is related to the maximum daytime heating of the earth's surface, since high temperatures contribute ...
