Severe weather:
1. Lightning ( i think, picture isn’t clear)
2. Hurricane
3. Tornado
How it forms and moves:
1. Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Negative charge at the bottom of the storm cloud wants to link up with the ground's positive charge.
2. Hurricanes form when warm moist air over water begins to rise. The rising air is replaced by cooler air. This process continues to grow large clouds and thunderstorms. These thunderstorms continue to grow and start rotating.
3. Tornadoes form when warm, humid air collides with cold, dry air. The updraft will begin to rotate if winds vary sharply in speed or direction.
Scale used to measure intensity:
1. Nothing (not sure)
2. The Saffir-Simpson Hurricane Wind Scale.
3. Enhanced Fujita Scale
I hope this helps ^^
