Weather Worksheet

1. Moist air (humid air)
Uplifting force (pushed upwards)
2. Lightning
Hail
3. Counter clockwise = cyclone = low pressure
4. No, because to have a tornado, you must have two air masses, hot and cold, meet and start spinning so fast, that it forms a vortex, and touches down. 
5. A hurricane gets weaken because there is no more source of moisture. Instead of the ocean, it is now land. 
6. The wider the funnel cloud, the slower the wind speed is at the base. If the funnel is small and condensed, it will spin at 500km per hour, and be an F5.
7. Trees uprooted, shingles pulled off houses, moderate to severe damage, trains overturned, heavy cars lifted off ground. 
8. There’s an air current at 90 degrees to something. This creates a vacuum. Air around must come in to fill this vacuum from all around. Because jet streams act out the Bernoulli Principle, pulling air up. Jet streams provide the “uplifting force” needed for a thunderstorm. 
9. Low pressure, cyclone, counterclockwise. 
10. Lots of precipitation and cold temperatures.
