The Golden RuleInstructor and students all show:
Mutual Respect!
Lecture 1-Nats 101 15
Literacy RequirementsAlthough the writing requirement for this course is negligible, there is a science literacy requirement:
• 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
Oceans
Clouds, Rain, Fresh Water
Erosion by Water and Wind
Life, Life on Land
Blue Skies, Red Sunsets, Twilight
Sound
Lecture 1-Nats 101 22
Importance of Atmosphere
• Point 1- Offers Protection
Consider surface temperatures
Without atmosphere?
0oF global average, large diurnal swings
Similar to the Moon’s Climate
With atmosphere…
60oF global average, moderate diurnal swings
Lecture 1-Nats 101 23
Importance of Atmosphere
• Point 2 - Offers Protection
Consider Surface Radiation
Shields against harmful UV radiation
Lecture 1-Nats 101 24
Importance of Atmosphere
• Consider Survival Time
Without Food
few weeks
Without Water
few days
Without Air
few minutes
Lecture 1-Nats 101 25
To Understand the Atmosphere
Examine its interfaces

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
summer• 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:
http://www.wrh.noaa.gov/twc/monsoon/monsoon.php
http://www.atmo.arizona.edu/products/models/forecasts/forecast.html
• CONCERN: Our monsoon & rainfall may be changing
Lecture 1-Nats 101 28
Local: 2005 Monsoon Rainfall
• Record water flow through the Sabino and Rillito Creeks on July 31
• Rillito flow higher than Colorado river!
