Questions for review:

Ch. 2: 3-18

Ch. 3: 1-6, 8, 10-14, 19

Ch. 4: 1-11, 13-15

Know the different ways water vapor is characterized:

vapor pressure, saturation vapor pressure, relative humidity, specific humidity, dew point temperature, wet bulb temperature

Be able to use the saturation vapor pressure versus temperature curve to convert from dew point to vapor pressure and visa versa, and determine the saturation vapor pressure knowing the air temperature and then use the vapor pressure and saturation vapor pressure to determine the relative humidity

What are the two factors that cause relative humidity to increase and decrease?

Be familiar with and be able to distinguish between the four modes of heat transfer: conduction, convection, latent heat and radiation

Amount of radiation emitted from an object depends on its temperature (Stephan Boltzmann law)

Know what albedo means

Why the maximum surface temperature is in the afternoon (not noon)

Why the warmest days of summer are ed of July-early August , not June 21

What causes temperatures to be higher in the summer than winter

Diurnal changes in surface temperature and the atmospheric temperature just above the surface

Be able to use heat index and wind chill charts to determine how warm and cold the air feels

Be familiar with Figure 2.14 on Global Energy Balance

How does Tucson differ from the global average
