Many thunderstorms occur in nature and a thunderstorm that causes the most harm is the tornado. And it’s been a wonder for many how tornadoes form. There are some causes for the formation of those tornadoes, or any type of thunderstorm. It is noted that whenever there is a collision of a massive volume of air. It so happens that warm air and cold air may be present together. That the warm atmosphere is under and the cod air over. This warm air will attempt to rise up and a low pressure area may build up and this may cause the creation of the tornado once the updraft of air is large. The tornadoes occur only in certain areas and not in most places because they occur only when a particular climatic condition is attained.
A sudden change in the direction of wind was observed before the formation of a tornado. When it is being developed the rate of wind increases and this high speed wind begins rising upwards. This might cause a horizontal spinning effect in the lower atmosphere region. Later this shift in direction and the effect is seen to be formed in the vertical direction. Now at this stage as the thunderstorm that is being shaped starts its upward vertical travel the circumference grows and it may become very large and range anything between two to six miles.
A rotating wall cloud or a lower cloud base is said to be shaped in the area of wind direction. This slowly expands and becomes into a tornado.
The tornadoes can be classified into three categories based on the factors of the formation like weak, strong and violent tornadoes. The things that affect their formation and affect may vary and depend on wind speed, lifetime and reports about tornado deaths. A detailed study also demonstrates that the majority of the tornadoes are weak and almost half of them are strong and only a small number of them are violent in nature.
It has come to the notice after a long observation that rain doesn’t occur in the region of the tornadoes however there might be heavy to moderate rainfall in the background. Thus this is a brief account of how tornadoes appear to form.
