4. On the Fujita Scale, a tornado rated F3 would have what range of wind speeds? 207-260 mph 158-206 mph 113-157 mph 261-318 mph

5. Tornado activity begins in late winter and migrates in what direction? north east south west

6. What is the distinguishing feature of a supercell thunderstorm? heavy rain and hail mesocyclone anvil tornadoes

7. CAPE and LI are indices which are used to determine: instability position of fronts wind shear likelihood of storm rotation
