What is the definition of an air mass and what two factors distinguish air masses from one another?2. What are the letters used my meteorologists for classifying air masses?3. What air mass classification affects the Northeastern and Pacific Northwest areas of the U.S. during the Winter months? 4. What air mass classification is common during the Arizona monsoon?5. What is a weather system and what is its temporal and spatial scale?6. Define a Cold Front and what types of weather conditions are typically associated with these types of fronts? 7. Define a Warm Front and what types of weather conditions are typically associated with these types of fronts?Lab 6 Jurjevich8. What is a stationary front?9. Why can we generally expect strong thunderstorms, potentially heavy rain, hail, and even tornadoes with a cold front but not with a warm front? 10. List the 3 types of cyclones and briefly describe each type. 11. Where is Tornado Alley (approximately)? Does Tornado Alley shift and if so, during what season and to what area?12. The name of the scale that measures the intensity of Tornadoes is calledthe _____________scale.13. What are the 3 primary conditions required for the development of a strong tropical cyclone?14. The name of the scale that measures the intensity of Hurricanes is called the _________________scale.15. The aforementioned scale in #14 uses what three factors to categorize hurricane strength?Lab 6 Jurjevich16. What are some associated problems with hurricanes once they make landfall? What causes the majority of Hurricane deaths?17. List the three strongest Hurricanes (based on pressure) to make landfall in the U.S.18. When observing a satellite image of a hurricane, how do we generally determine the strength of the system?19. Briefly describe the life cycle of a tropical cyclone (from an Easterly wave to a Hurricane) by explaining the categorizations and naming based on wind speeds. 20. What is the difference between a Hurricane, Typhoon, and Cyclone?21. What is the official definition of a Blizzard?22. What is the official definition of a Severe
