2.  Be able to describe why microbursts can cause deadly plane accidents.

3.  Missing flood projects.  Test on Meteorology this Friday (4/10). ◦ Hurricanes ◦ Tornadoes ◦ Lightning ◦ Floods ◦ Microbursts

5.  A microburst is a strong downdraft, less than 2.5 miles in diameter, associated with thunderstorms.  This concentrated column of sinking air can be very dangerous, even though they only last a few minutes.

6.  There are two types of microbursts and about 8,000 total microbursts a year in the US.  Wet Microburst ◦ Has rain  Dry Microburst ◦ Doesn’t have rain

7.  Wet and dry microbursts can occur every where.  Dry microbursts are most common in the midwest/west.  Wet microbursts are most common in the southeast.

8. 1. What is a microburst? 2. How many microburst occur each year in the US?

9.  Normally formed by precipitation-cooled air rushing to the surface.  Can also be formed by high speed winds deflecting towards the ground by a thunderstorm.  Winds speeds around 170mph

10.  Downburst develops as the downdraft begins its descent from a cloud base.

11.  This is the outburst stage where the winds curl as the cold air moves away from the point of impact.

12.  This is the cushion stage. The winds about the curl continue to accelerate, while the winds at the surface slow due to friction.

14. 1. What are the 3 stages of a microburst?

16.  Missing flood projects. ◦ CJ  Test on Meteorology this Friday (4/10). ◦ Hurricanes ◦ Tornadoes ◦ Lightning ◦ Floods ◦ Microbursts

17.  Know the dangers of microbursts.

18.  A photograph of the surface curl soon after a microburst impacted the surface

26.  Microbursts are particularly dangerous for pilots because of their very strong winds going to every direction.  Microbursts only last from a few seconds to a couple of minutes so they are tricky to track or predict.

27.  Dry microbursts can be invisible to the naked eye so they can really catch a pilot off guard.  Microbursts are less than 2.5 miles wide so they can sneak up quickly.

32.  Why are microbursts particularly harmful to aircraft?

33.  Besides tearing planes out of the sky microbursts can cause some other serious damage.  Microbursts can cause damage paths similar to those created by tornadoes.

37.  Microbursts can destroy houses, and trees.  Can turn objects into projectiles just like a tornado.  Need to watch out for flying debris.
