1 EAS 101 SAMPLE TEST 1 ON MATH PROBLEMS SHOW ALL WORK 1. Describe and explain the basic cause of the winds. 2. Tell whether weather near the equator is generally (wet, dry) and the weather in the subtropics is generally (wet, dry) and then Explain. 3. How does air have to move to produce clouds and precipitation? Explain. 4. Fill in the data for the circled weather station and find the front on the Surface Weather Map on Slide #2. 5. Draw a small raindrop and an ice crystal. 6. In Slide #3, draw a cumulus cloud and a cirrus cloud. Include relative positions of the clouds, the air motions that produce them and explain how each gets its shape. Use the 2 km high mountain for scale. 7. In Slide #4, draw the pattern of clouds associated with a warm front of a winter storm and then list the sequence of clouds that an observer sees as the storm approaches? Label warm and cold air masses. 8. On Slide #5, draw the path light takes through an ice crystal to produce the 22º halo. Label what happens to the light at each juncture. 9. On Slide #5, draw the path light takes through a raindrop to produce the primary rainbow. Label what happens to the light at each juncture. 10. Explain how a rainbow or halo is used to forecast weather. 11. Explain how crepuscular rays form and why they appear to diverge. 12. Explain why the sky is blue and why the sun turns orange or red at sunset. 13. Explain why so much less Ultraviolet Radiation reaches the ground when the Sun is low in the sky than when it is high in the sky. A drawing might help. 14. Describe properties of electromagnetic waves, including wavelength, amplitude, speed, frequency, and relative energy levels. In the diagram in Slide #6, show the relative lengths and frequencies of infrared radiation, radio waves, ultraviolet radiation, the visible light spectrum (with its colors), and X-rays. 15. On Slide #7, draw the Earth on December 21 including day and night, the latitude where the sun is overhead, and the regions of 24 hours of day and 24 hours of night. 16. On Slide #8, draw the solar declination vs month and then draw the Sun paths for April 21 at latitude, 55º South and North Latitudes. Label all noon zenith angles. IF THERE IS TIME THEN ALSO INCLUDE 17.* Find the irradiance of direct sunlight on Pluto when it is 40 times further from the Sun than Earth and when direct sunlight on Earth is 1370 W m -2. 18.* If direct sunlight has an irradiance = 1370 W m -2 when solar zenith angle, Z = 0  (the Sun is overhead), find the irradiance on a surface when the Sun is 55  from the Zenith (Z = 55  ).
