After reading the section Relative Humidity and Human Discomfort in chapter 4, construct an engaging 3-paragraph initial post that addresses the following points:

    Paragraph 1:  Differentiate between what temperature and dew point temperature each describe about atmospheric humidity.  Then, define dew point depression, and explain what that describes about atmospheric humidity. (Remember from chapter 4 that the word humidity is a general term for some measure of atmospheric water vapor.) (graphics will add greatly to the discussion here).
    Paragraph 2: Explain why the phrase, Its not the heat, its the humidity. has validity on a day where both the air temperature and relative humidity are high.  Hint:  define the heat index and explain what it tells us about what the air feels like, by discussing how both a high temperature and high relative humidity negatively impact the bodys ability to cool itself (graphics will add greatly to the discussion here). 
    Paragraph 3:  Relate a personal experience to the discussion in paragraphs 1 and 2.
