1. Similarities Between Tornados and Hurricanes
Low Pressure
Latent Heat of Condensation
Strong Winds
Hazardous to Life and Property

2. How do they differ?
Location
Size (300 miles vs. mile)
Duration
Season of Occurrence
Distinctive Hazards
3. Layers of the Atmosphere
Thermosphere
Mesosphere
Stratosphere
Troposhpere
Temperature is how they are divided
4. What is the greenhouse effect?
Ground is heated by visible and some infrared light from Sun (short wave)
Heated surface emits IR light (long wave radiation)
5. 4 Types of Thunderstorms
Single Cell
Multicellular
Supercell
Severe thunderstorms
6. How is a cloud formed?
7. How is a cloud formed?
8. How is a cloud formed?
9. Air Masses
10. High Pressure
Anticyclonic circulation
Cool air sinks
Clear skies, more sun = more short wave radiation
11. Low Pressure
Winds are cyclonic and wind near earth surface flow toward LP
Warm air rises
Cloudy skies cause lower temperatures during the day
12. Classifying Clouds
Form
Cumulus (heap)
Stratus (layer)
Cirrus (curl of hair)
Nimbus (rain producing)
Height
High
Middle
Low
Vertical development (cross height categories)
13. How does wind happen?
Pressure Gradient Force
Initiates air motion
Distribution across globe varies, which explains air motion/winds
Coriolis
Air in motion in the North(South) is deflected to the
Friction
Terrain will affect how wind blows over it
14. 4 Lifting Mechanisms of Air
Orographic Uplift
Convection
Frontal Lifting
Convergence
15. Albedo
The reflective quality of the surface
Light color = high albedo
Dark color = low albedo
16. Different Types of Spheres
Geosphere
All processes associated with the solid earth
Hydrosphere
All processes associated with water
Atmosphere
All processes associated with the gases that envelope the earth
Biosphere
All processes that involve living organisms
17. Radiation
Short wave = Sun
Long wave = Earth
18. Ozone in Stratosphere
Forms naturally
Absorbs UV Rays
One CFC can decompose < 100,000 O3
19. Thermal/Temperature Inversion
When the surface cools rapidly,pollutants or moisture can be trapped below warmer air (inversion layer)
Forms a haze over an area
20. Gases in Atmosphere
Nitrogen
Oxygen
Argon
21. Mid Latitude Cyclones
They are one of the primary weather producers in the mid lats.
They are large (~2,000 km), moving atmos. vortices with centers of low atmos. pressure
Can last a few days to more than a week and cover large portions of the continent
Can bring abrupt changes in wind, temp, and sky conditions.
Tend to be stronger and more numerous in fall, winter, and spring!
