KEY TERMS

 

TEST9:  Chapters 16, 17, 18, 19/Extra Credit: Chapter 20: Origin of Modern Astronomy

 

Homework assignment:  Please, research these Key Terms in your textbook, study guide, and other documents you may have. You will be tested on the objective and key terms outlined below to ensure that you have mastered the basic knowledge in this atmospheric section. You will have 4 or more extra credit questions on chapters 20 (Astronomy) that count for 20% or more.

CHAPTER 16:     Moisture, Clouds, and Precipitation

 

 I - Changes of State of Water

                 Latent heat (definition and role in atmospheric processes)

 Calorie (kilocalorie), calorie (definition and relation)

II - Humidity

Definition and role in atmospheric processes

Relative humidity/Saturation (definition, how does it relate to condensation, temperature, and water- vapor content?)

Dew point (definition, how does it relate to the actual moisture content, temperature, and water-vapor content?)

Adiabatic temperature changes: How does it produce condensation?

Condensation and cloud formation: Name the major clouds producing rain and storm

Types of fog; what causes fog?

III - Adiabatic heating/cooling

                What happens when air is compressed/expanded?

                W hat happens when moist/dry air ascents?

                Wet/Dry Adiabatic cooling rate (explain)

Processes that lift air: Orographic lifting/rain shadow desert (i.e. west coast US), frontal wedging/middle-latitude cyclones (i.e. middle latitude), convergence/afternoon thunderstorms (i.e. Florida), and localized convectice cells (i.e. Urban Heat Island)

How and why the Florida peninsula experiences so many midafternoon thunderstorms?

 

                                               

CHAPTER 17:     AIR PRESSURE AND WIND

 

I - Air Pressure

How do temperature and pressure vary with altitude in the troposphere?

How is air pressure measured?

II - Wind

                What causes wind, and how does wind flow?

                Pressure Gradient/isobars spacing (how does it relate to wind speed?)

                Coriolis effect (Cause/ how does it affect wind direction in the two hemispheres?)

III - High/Low Pressure

Low Pressure center: Cyclone (definition, type of weather is associated with it and why, convergence, and divergence)

High Pressure Center: Anticyclone (definition, type of weather associated with it and why, convergence, and divergence)

IV - General Circulation of the Atmosphere:

                Equatorial low/Subtropical high (origin, flow pattern, and relation to subtropical deserts)

V - Local Winds:

                Land breeze/leeward coast (see also page 426: Geographic position)

                Sea breeze/windward leeward coast (see also page 426: Geographic position)

                Valley breeze?

VI - El Nino/La Nina

Explain how El Nino and El Nina form along the eastern tropical pacific, and how they are related to pressure variations between the East coast (S. America) and the West Coast (Indonesia, Australia).

What are the effects of El Nino and la Nina on the climate in US, especially in 1997-1999?

Why is it called the Southern Oscillation?

How does the El Nino phenomena affect the number of hurricanes in the Atlantic?

How can La Nina phenomena affect the hurricane season in the Atlantic?
