From the Paper:

""Tornado" comes in English from a Spanish word "tornado" that means "thunderstorm". As defined by Nation Weather Service, a tornado is a "violently rotating column of air in contact with the ground and pendant from a thunderstorm". Tornadoes result when there is stuffiest amount of moisture in the atmosphere at lower and mid levels, and when this condition gets combined with warm unstable air that rises above due to a lifting force. Initially, there should be some reason to cause air to flow upwards and to contribute in the formation of a tornado. This happens due to the fact that warm air is considerably lighter in weight than cold air (Earthbulletin). The buoyant air is produced as atmosphere gets heated near the ground surface. The heated air, which is warm and light, begins to rise upward and if during this phenomenon, a thrust of cool air is met, it further instigates the upward motion of air and could possibly trigger a thunderstorm."
