Tornados!

I was recently asked why tornados tend to take the same path?

We see that tornados do follow similar paths year after year… but they CAN happen any where. They usually happen in the central United States, Oklahoma, Missouri, Illinois, Kansas, and Texas. Agricultural areas… WHY?

Tornados need three things to form: moisture in the air, (for thunderstorm development) which those areas have otherwise crops wouldn't grow. They also need heat (for a lifting mechanism) and the change in the temperature, and finally, wind shear (typically a low level jet; shears cause rotation in the vertical, which is translated to horizontal rotation eg: tornadoes)

All conditions are met in agricultural areas, like the central US. That’s why tornadoes seem to follow the same path… their conditions are optimal. However, tornados can occur anywhere! Also in Europe, and SE Asia. They have been known to climb the Appalachian mountains, and be present in Yellowstone National Park, and cross rivers!

Believe it or not, it is possible for a tornado to strike the same area, even the same town more than once. A town in Kansas got hit on the same day, three years in a row. 1916, 1917, 1918. And once a church in Arkansas got hit three times in one day! So, there you have it. That’s why it seems tornados follow the same path, the follow the weather conditions, like we do!

  1. I heard all of my life, you always see spiders (more of them) when it is going to rain. This is no doubt an old wives tale, but it does seem to be true. Is it and why?

  2. Basically, spiders are just looking for shelter, like we would. And shelter may happen to be our homes or offices.

    It is thought that many animals such as cows, cockatoos, crickets, and spiders, among many other animals can predict wet weather because we see more of them before rain storms; the reality of that is still to be determined.

    Would you really deprive them of being dry?

    Hope that clears some of the air! I look forward to many more of your questions! :)
