What are the
potential warning signs?
How do you measure
* EF scale (Enhanced Fujita scale)
* Intensities range:
Other tools used to
* Doppler Radar
How do tornadoes
It is not fully understood as to how exactly tornadoes form, grow and die. Meteorologist are still trying to solve the tornado puzzle. Every time a piece fits in, it uncovers a new piece which needs to be studied.
Who benefits from tornadoes?
Benefits from tornadoes:
* Vehicle repair shops
* Construction businesses
* Insurance adjustors
* Helps maintain a relative equilibrium in the atmosphere.
