1. Meteo 003: Lab 4 Chapter 4: 14ab, 15c Chapter 5: 4abc, 10ab, 18 Chapter 6: 2ab, 7ab, 9acd Chapter 7: 9ab

2. 4.14a,bpg. 163 Isohyets: isopleths of rainfall a) -same guidelines as all isopleths Hint: you’ll have to draw circles in places b) -prevailing winds are northeasterly -draw an arrow of the wind direction -air rises on windward side of a mountain

3. 4.15cpg. 164

4. Apparent Temperature Example Find the apparent temperature for a day given that the air temperature was 80 F and the dew point was 70 F.

5. 5.4a,b,cpg. 200 Type of ImageryVisibleInfraredWater Vapor ColorDarkerLighterDarkerLighterDarkerLighter InterpretationClearerCloudierWarmerColderDrierMoister a,b) -Connect concepts to images -Refer to pages 180-183 in the textbook -Water vapor imagery can only tell us about water vapor content in upper troposphere. Why? See pages 180-183. c) -Which form of radiation has wavelength in the range of 0.4-0.7 microns? (for black and white or grayscale images)

6. 5.10a,bpg. 205 a) -Which imagery is used to determine albedo? -Consider your answer from 5.4.c -High albedo = reflecting more, low albedo = absorbing more b) -Which imagery reveals information about temperature? -Refer to table in previous slide

7. 5.18pg. 211 -Radar beams are sent out at an angle -For the snow showers to not be seen by the radar, what must be true?

8. 6.2a,bpg. 243 Pressure Gradient Force: the force that directs air from higher toward lower pressure. *always points from high to low pressure *perpendicular to isobars (gets from high to low pressure fastest this way) -Think about when you’re pumping up a sports ball and air comes out a) -Wind blows away from higher pressure and toward lower pressure -Make sure to draw about a dozen arrows b) -Would the pressure gradient force be different in the Southern Hemisphere?

9. 6.7a,bpg. 248 -Surface pressure at different locations need to be converted to sea- level pressure to be able to compare -Pressure decreases with height in the atmosphere a) -Use pressure decreases 10 mb for every 100 m of elevation Ex) What is the corrected to sea-level pressure of State College, PA if the surface pressure was measured to be 965 mb and the elevation is 350 m?

10. 6.7 cntd… b) -Pressure is lower at higher elevations -That’s why the air is thinner and harder to breathe in places like Denver, CO -How would a map of pressure look if left uncorrected to sea-level?

11. 6.9a,c,dpg. 249 *NO part b a) -Identify Highs and Lows by finding relative maxima of closed isobars c) -Wind barbs show the direction the wind is coming from -Consider how wind flows around High and Low pressure systems d) -In general, the tighter the isobars, the faster the wind speed -This is due to a stronger pressure gradient force

12. 7.9a,bpg. 300 -A warmer column of air will have higher heights on a given pressure surface when compared to a colder column of air a) -Determine which location is warmest, which is coldest? -How would the temperature of each location affect the height of any given pressure level? b) -Use the same concepts from part a but instead of different locations think of different seasons
