Altitude & temperature lapse rate

Answers and reasoning. Review before teaching.

  1. 1. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 67° N (using 90° − latitude)?

    23°

    At the equinox, noon solar elevation = 90° − 67° = 23°.

  2. 2. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 62° N (using 90° − latitude)?

    28°

    At the equinox, noon solar elevation = 90° − 62° = 28°.

  3. 3. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 27° N (using 90° − latitude)?

    63°

    At the equinox, noon solar elevation = 90° − 27° = 63°.

  4. 4. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 59° N (using 90° − latitude)?

    31°

    At the equinox, noon solar elevation = 90° − 59° = 31°.

  5. 5. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 39° N (using 90° − latitude)?

    51°

    At the equinox, noon solar elevation = 90° − 39° = 51°.

  6. 6. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 69° N (using 90° − latitude)?

    21°

    At the equinox, noon solar elevation = 90° − 69° = 21°.
