METEO 003
Section 2Lab 2: Due Sept. 12
Revisit Lab 1: • Wind direction
East Wind = Winds are coming from the EAST and moving WESTEasterly Wind = From the EastEastward Wind = From the West
• Stefan-Boltzmann equation where σ = 5.67x1if an object has a Temp of 294.15 K and is absorbing 500 of energy we only know if
it is increasing or decreasing if we do the math , energy emitted = 306 K

Review of Assignment 1
• Problem 7a, b:• use graph paper or Microsoft Excel
• Don’t forget to label title, axis, legend, etc.
• Interpret the graph you make in part a for part b
• Problem 10a, b:• Clouds radiate in all directions
• Downwelling Radiation – downward emission of infrared energy
• Carefully read axis/axis labels of graphs
• The picture on the right is on pg 64, the discussion there may be useful

Chapter 2: Problem 11a, b:IR Satellite ImageUpwelling Radiation
Why is scale showing temperature for an Infrared Satellite Image?Stefan-Boltzmann equation (E = σT4)
Visible Satellite Image Infrared Satellite Image
• Chapter 2: Problem 13a, c, d: • UV Index – measurement of the strength of ultraviolet (UV) radiation
from the sun at a particular place and time• Table on page 81 not 83• Reference: http://www.epa.gov/sunwise/doc/uvradiation.html
• Chapter 3: Problem 1• Use State College latitude as 40.8N
• Reference pg. 86• Equinoxes: Autumnal and Vernal• Solstices: Summer and Winter
• Determine the maximum altitude of the sun
Example:
Need to know:Latitude of your location: 39NLatitude at which sun is directly overhead: 10N
Difference = 39N – 10N = 29°*Note: be careful when latitudes are in different hemispheres
Maximum altitude of the sun = 90° – D = 90° - 29° = 61°
• Chapter 3
• Problem 4, 6, and 9a,b,c:
• Continental locations have larger seasonality than coastal regions
• Prevailing winds off the water result in less seasonality than off the land
EXAMPLEAverage January High
Temperature (F)Average July High Temperature (F)
Seasonality (F)
City 1 60 93 33
City 2 58 72 14
City 3 39 90 51

Assignment 2 due Sept. 12Chapter 2 – 7a,b, 10a,b, 11a,b, 13a,c,d
Chapter 3 – 1, 4, 6, 9a,b,c
Useful Equations• From pg. 57, the Stefan-Boltzmann equation E = σT4
• Maximum altitude of the sun = 90° – Difference
