Investigate the location, magnitudes and frequencies of natural hazards Bell Ringer – Take out your bell ringer paper. Copy and answer the following question. 1. How do tornadoes form?

30. Agenda for today: 1. Complete questions from yesterday. 2. Go over questions 3. Begin Video on Severe Weather 4. Complete Exploring Weather: Severe Weather mini quiz

31. Severe Weather Assessment Questions 1. What makes one thunderstorm more severe than another? The increasing instability of the air increases the strength of a storm’s updrafts and downdrafts, which makes the storm severe. 2. Describe Two characteristics of thunderstorm that lead to hail formation. One characteristic – Water droplets enter the cloud where temperatures are below freezing. When the water droplets are super cooled they hit ice pellets. The water droplets form layers around the ice pellets to grow larger. The second characteristic is strong updrafts and downdrafts, so that the ice pellets constantly encounter more super cooled water droplets. They keep growing until they are too heavy for even the strongest updraft to carry them back up into the clouds.

32. 3. Explain how some hail can become baseball sized. Hail can become baseball sized if the wind is strong enough to push the ice pellets back up into the clouds to form new layers of ice over and over again until it becomes baseball sized. 4. Compare and contrast a macroburst and a microburst. Macroburst can cause a path of destruction up to 5km wide. They have wind speed up to 200km/hr and can last up to 30 minutes. Microbursts can cause a path of destruction 3km wide. They have wind speeds up to 250km/hr and can last up to 10 minutes on average.

33. 5. Identify the steps that change wind shear into a tornado. 1. A change in wind direction and speed creates a horizontal rotation in the lower atmosphere. 2. Strong updrafts tilt the rotating air from a horizontal to a vertical position. 3. A tornado forms with the rotating winds. 6. Identify the conditions that lead to high winds, hail, and lightning. Instead of dispersing that downward energy ova a large area underneath the storm, the energy becomes concentrated in local areas. The resulting winds are exceptionally strong, with speeds of more than 160 km/hr.

34. 7. Explain why there more tornado – producing storms in flat plains than in mountainous areas. Large temperature contrasts occur frequently in the United States, where cold continental polar air collides with maritime tropical air moving northward form the Gulf of Mexico. These large temperature contrasts occur most frequently in the central United States. 8. Analyze the data of the Fujita scale, and determine why the F5 tornadoes have a longer path than F1 tornadoes. The F5 tornadoes have a longer path than F1 tornadoes because there is more wind energy to back up the tornado. The F5 has wind speeds 333 – 512+ km/hr compared to the F1 which has wind speeds up to 180km/hr.

35. Exploring Weather: Severe Weather Video 1. In which layer of the Earth’s atmosphere do thunderstorms form? 2. True or false: Thunderstorms are more common in the tropics than polar regions. 3. Thunderstorms occur along a __________ between two masses of air. 4. Lightning heats up the air causing the air to expand. This results in _____________.
