What Causes Tsunamis
What are Tornadoes?
People often wonder about tornadoes, which impacts a place with such a strong force, mostly in continental united states, that even the things as massive as cars or trees are carried away by the catastrophic winds blowing through the area.
We discuss here what actually is a tornado? What are its causes and effects?
Tornado is a natural phenomenon associated with violently swirling winds, reaching up to 300 miles per hour in speed.
While in an active mode, it encircles the whole column between the earth’s surface and above clouds. In other words, an observer, if he by some means withstand the winds, would visualize the whole rotating wind column from the floor connecting the sky.
Its Occurrences date, time and areas of impact:
Though tornado can be experienced in Europe or other parts of the world, but its common breeding ground is the north American continent.
Its causes would be discussed below under the causes section.
Tornadoes begin in spring and continue throughout the summer season. In other words, it impacts the lands in the month of April through August.
The most probable time of its occurrence is in the evenings.
The south eastern states of the United States are the first to experience the activity starting from the month of April.
In Later months, Tornadoes move upwards to the central states of the US.
Some of the southern Canadian states are the last ones to experience the effect in the months of august.

So why tornadoes most often occur in continental united states? .
The reason is the typical geographic terrain and ocean locations, which makes the continent an optimum place for tornadoes.
What happens is: At the start of the spring season and later on in summers, the tropical waters of south western Atlantic oceans are heated enough to generate warm& moist air, which tend to flow pole wards in the higher latitudes.
On the other hand, arctic air masses, which are relatively cold due to less solar heat reaching the polar region, sink down and tend to flow towards the lower latitudes.
The place where these two contrasting air masses clash with each other is the point where tornadoes occur. The swirling wind activity is actually the shearing of the arctic and tropical air masses.
Why spring is the ideal season for tornadoes?
The reason being at this time of year, we have both the warmth ocean in the southern gulf of Mexico as well as sudden outbreaks of cold weathers in higher latitude areas. Thus, spring is the ideal season for catastrophic air masses clash.
