1. Meteo 003: Lab 2 Due Friday Sept. 11 th Questions: Chapter 2 – 7ab, 10ab, 11ab, 13acd Chapter 3 – 1, 4, 6, 9abc 40 Points Total

2. Chapter 2 – 7ab, 10ab, 11ab, 13acd Chapter 3 – 1, 4, 6, 9abc Topics Covered) Seasonality Nighttime Radiation Interpreting Images/Graphs Sun Angles Climatology Land/Water Effect on Climate

3. 2.7pg. 77 a) Graphing radiation as function of latitude Recommend using Excel Graphs need titles, labels, and units b) Interpreting graphs Think of what factors effect the seasonality and climate of a location

4. 2.10pg. 78 a) Interpreting graphs of radiation *Note the different scales on the y axis Defn: Downwelling Infrared Radiation – downward emission of IR radiation b) Connect radiation to temperature

5. 2.11pg. 79 a) Connect radiation and temperature Think Stefan-Boltzmann Law Compare radiation map to satellite imagery b) Satellite imagery should give you answer Again compare temperature to radiation

6. Satellite Imagery Example

7. 2.13pg. 80 *Note: NO part b a) Familiar product: UV Index Good site to reference: www.epa.gov/sunwise/uvradiation.htmlwww.epa.gov/sunwise/uvradiation.html c) Reference above site d) Interpret graph Use site for more help

8. 3.1pg. 111 Use 40.8 N for State College Need to make 4 calculations Think of where the sun is overhead during the Solstices and Equinoxes Consider the sign of latitude in northern and southern hemispheres Equation needed: Max altitude of Sun = 90 – D where D is the difference between the latitude of the location and the latitude where the sun is directly overhead

9. Sun Angle Example Washington, DC is located at 39 N. Determine the maximum altitude of the sun during the Winter Solstice.

10. 3.4pg. 112 Determining the seasonality and climatology of locations Consider the latitude, proximity to water, prevailing wind, elevation

11. 3.6pg. 113 Similar to 3.4 Use same considerations Although latitude is no longer issue Wind will play a larger factor

12. Seasonality Example

13. 3.9pg. 115 Features should be fairly easy to spot Know your geography c) Think about the same guidelines used in 3.4 and 3.6

14. Chapter 2 – 7ab, 10ab, 11ab, 13acd Chapter 3 – 1, 4, 6, 9abc Due Friday Sept. 11 th 40 points total Thursday Office Hours: Astrid (ais5396@psu.edu): 10-11 AM in 623 Walker Josh (jig5374@psu.edu): 2-3 PM in 6 th Floor Walker Wx Center Zach (zmg5025@psu.edu): 4-5 PM in 6 th Floor Walker Wx Center
