3.12ab
• a) Gulf Stream– Originates in the Gulf of Mexico,
travels around the tip of Florida and continues along the eastern coastline.
– Current of relatively warm ocean water.
• b) Map interpretation– Use the color coding on the map
to interpret temperatures.
3.13abcde
• All about Seasonality – Large bodies of water moderate temperature• Coastlines and islands vs. landlocked areas
– Prevailing wind direction • West coast vs. east coast
– Location of Gulf Stream (Part e)
3.15ab
• a)– To compute the diurnal range,
average the difference between maximum and minimum temperatures over the 10 years of data.
• b)– How would clouds affect max
and min temperatures?

3.16b
• Albedo- Amount of solar energy reflected back into Space– Dark objects have low albedos (absorb more than
reflect)• Asphalt, soil
– Light objects have high albedos (reflect more than absorb)• Ice, snow
4.1a
• Relative Humidity– How much water vapor is
present compared to how much before the air becomes saturated?
– Warm air can contain more water vapor than cold air.
• Given Dew Point is constant• What does this mean in
terms of water vapor present throughout the night?
4.1b
Dew Point Depression = Temperature – Dew Point• Things to consider– Time of day dew point depression is greatest/least– What happens when dew point depression = 0?
4.2
• Fog can be considered a low lying cloud.
• Fog forms where air is saturated. – What does the dew
point depression equal when air is saturated?
4.6
• Relative Humidity = Vapor Pressure/ Equilibrium Vapor Pressure * 100%
• Given 2 out of 3 variables in equation, you will solve for missing variable
• Ex).RH = 75%Vapor Pressure = 9mbEq. Vapor Pressure = ?
4.7b
• Pacific Ocean Vs. Gulf of Mexico– Which is generally warmer/colder?– Higher temperatures increase
evaporation rate, lead to more water vapor in the atmosphere
4.8
• Density = mass/volume• Given two parcels of air with equal volumes.• Calculate molecular mass to determine
density of air. • Ex). Oxygen = 16AMU, Hydrogen = 1AMU– What is the molecular mass of H2O?
• 2 Hydrogen + 1 Oxygen = 2 x 1AMU + 16AMU = 18AMU– What is the molecular mass of O2? N2?
