- What are tornadoes?
- They need an intense storm and the moist and dry air will create unstable air.
- A violent, dangerous, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud
- How does the urban area contribute to the tornado hazard?
- Heat island effect- impermeable surfaces like glass, metal and concrete reflect and store heat differently than tree or grass covered land.
- Urban environments heat the air and cause moisture to rise quickly- more heat, more energy.
