Lab 4A 1. Without an atmosphere, the equatorial curve would show minimum daily values on the solstices in June when the sub-polar point is located 23.5 degrees North and in December when the sub-polar point is at _____ latitude. b. 23.5 degrees South 2. The radiation curves represent equatorial, mid-latitude, and polar locations, whether on land or ocean. According to the curves, the average daily solar radiation varies the most over the period of a year at the ____ location. c. polar 3. The average daily solar radiation varies the least over the period of a year at the ____ location. a. equatorial 4. The greatest average daily solar radiation occurs at the polar location during ____. A primary reason why more daily sunlight is received during this month is because the length of daylight is 24 hours. Another major factor is that, although relatively low in the sky’s compared to the Sun’s noontime position at other Northern Hemisphere latitudes, this is the month when the Sun reaches its maximum altitude above the horizon for the entire day. b. June 5. The graph shows one location with 6 months of zero solar radiation. This period of continuous darkness is at the ____ location. Check the sunrise/sunset table for this location at Link 4A-2. c. polar 6. For each of the three curves, compare the annual range of solar radiation received (the difference between maximum and minimum values). As latitude increases, the annual range of daily solar radiation _____. c. increases 7. Note the positions of the equator and the 30 degrees North and 30 degrees South latitude lines. Figure 4A-2 shows that in February the highest tropical Pacific Ocean SSTs are largely ____ of the equator.

a. south 8. In February the Pacific Ocean SSTs are highest in the ____ tropical Pacific. b. Western 9. On the other hand, Figure 4A-3 shows that by August the highest tropical Pacific SSTs are mostly ____ of the equator. c. north 10. Using SST, how is heat moved from the equatorial region to the North Atlantic Ocean? (See Link 4A-4 for ocean currents.) c. Gulf Stream current 11. Warm tropical ocean water (usually above 26 degrees Celsius) sustains hurricanes and tropical storms. Examine Figure 4A-2 and Figure 4A-3. Which area is best suited for the storms to form? d. Equatorial Atlantic Ocean in August 12. Where does the biggest SST difference occur between February and August? Focus on the areas near 180 degrees longitude. c. 60 degrees North 13. In both February and August, SSTs off the California coast are ____ SSTs at the same latitude off the East Coast. This temperature contrast can be attributed to the southward flowing cold California Current, coastal upwelling along the West Coast, and the northward flowing warm Gulf Stream along the East Coast. We will visit all these topics in depth later on. b. lower than 14. Compare the latitude positions of the 20 degrees Celsius isotherms in the two hemispheres at the two times of the year. The orange belt of solar-warmed waters (20 degrees Celsius and higher) that straddles the equator is more northerly in ____. a. August 15. The same comparison of the two SST maps shows that the orange belt of solar-warmed waters (20 degrees Celsius and higher) is more southerly in _____. b. February
