       Literacy Requirements
  Although the writing requirement for this
  course is negligible, there is a science literacy
• Use scientific notation for writing numbers
     (especially rather large or small ones).
• Specify units of physical quantities
     (e.g. meters for elevation, etc.).
• Attempt to quantify physical relationships.

    Importance of Atmosphere
• Necessary for a wide spectrum of features
  Clouds, Rain, Fresh Water
  Erosion by Water and Wind
  Life, Life on Land
  Blue Skies, Red Sunsets, Twilight
                  Lecture 1-Nats 101      21
    Importance of Atmosphere

• Point 1- Offers Protection
  Consider surface temperatures
  Without atmosphere?
  0 F global average, large diurnal swings
  Similar to the Moon’s Climate
  With atmosphere…
  60 F global average, moderate diurnal swings

   Importance of Atmosphere
• Point 2 - Offers Protection
  Consider Surface Radiation
  Shields against harmful UV radiation

   Importance of Atmosphere

• Consider Survival Time
  Without Food
     few weeks
  Without Water
     few days
  Without Air
     few minutes

To Understand the Atmosphere
      Atmosphere               Examine its interfaces
                                 with land/ocean
                                 with space
Sun     Earth
       13,000 km
                                 Is a very thin skin
                                 99% below 50 km (31 miles)
                                 50% below 5.5 km (3.4 miles)

          Local Weather and Climate:
         The North American Monsoon
• Tucson gets half of its rainfall during the summer
• Sonora, Mexico gets most of its rainfall during the
• During summer, high pressure sets up to the
  east/northeast of Arizona which brings moisture in
  from the south and east
• The monsoon is still going: Thunderstorms yesterday
• For a monsoon overview and daily forecast, see:
• CONCERN: Our monsoon & rainfall may be changing

• Record water flow
  through the Sabino
  and Rillito Creeks
  on July 31
• Rillito flow higher
  than Colorado river!
