VI. Temperature in the Troposphere
    A. Three major influences
        1. Environmental Lapse Rate
        2. Heating Properties of Water
        3. Variable Insolation
    B. World Air Temperature Patterns
        1. Isotherms
        2. Decrease Towards Poles
        3. Continents Distort the Pattern
        4. Stable Equatorial Temperatures
        5. Variable Mid-latitude and Sub-Arctic Temperatures
        6. Elevation
        7. Ice Caps
