1. Bell Questions 12/19/14
What type of air would a maritime polar air mass have?
What are four kinds of fronts?

2. Severe Weather

3. Midlatitude cyclone - an area of low pressure characterized by rotating wind that moves toward the rising air of the central low-pressure region

5. Midlatitude cyclones are many of the storms that come across the US

6. Thunderstorm a brief, heavy storm
warm, humid air rising, updrafts
rain falls and drags some of the cooler air with it creating downdrafts
dissipating stage, strong downdrafts stop air from rising

11. Tornado rotating column of air high wind speeds (F5 is 318 mph)
funnel-shaped cloud
formed over land
Tornado Alley in the US has the most tornadoes in the world
Fujita scale

15. Hurricane
develops over tropical oceans
winds of more than 120 km/h (73mph)
low-pressure storm center
Storm surge, submerge coastal areas, causes most damage

16. Hurricane Isabel

17. Katrina 2005

22. Bell Questions 3/30/10
List two differences between tornadoes and hurricanes.
A _____________ ___________ is an area of low pressure, rotating wind that moves toward the rising air of the central low-pressure system.

23. Thermometer
measures and indicates temperature

24. Barometer measures atmospheric pressure
Drop in pressure means front is coming

25. Anemometer measures wind speed
small cups that are attached to a shaft that rotates freely.

26. Wind Vane
determines direction of the wind

27. Radiosonde
a package of instruments that is carried aloft by balloons to measure upper atmospheric conditions

28. RADAR
RAdio Detection And Ranging, a system that uses reflected radio waves to determine the velocity and location of objects
Doppler Radar measures particle movement in storms

29. Weather Satellites Observations that can’t be made from the ground
Wind speeds at cloud level

30. Weather Satellites

31. Computers
Supercomputers can solve complicated mathematical problems quickly
Store weather data

33. Weather Instruments Instrument Description and Use Thermometer
