Course Goals

• Develop a basic understanding of the Earths
  atmosphere including the role of weather and the
  legacy of climate
• Develop a basic working knowledge of how to
  diagnose the current state and predict the future
  state of the atmosphere from online resources
• Develop skills to understand, observe and
  anticipate severe and unusual weather and climate
  and embrace the awe that it endears

Grading for 101

• Lecture 75
• Discussion/Laboratory 25

8
Basic Lecture Structure

• 10-15 minute discussion of current weather,
  pointing to applications of the current topicon
  special occasions, this discussion may take
  longer or all of the class time
• Answer questions from class regarding reading
  assignment
• Lecture designed to expand and embellish selected
  topics from reading or introduce topics not found
  in reading

9
Text Book

• Severe and Hazardous Weather
• An Introduction to High Impact Meteorology
• (4th Edition)
• By Robert M Rauber, John Walsh, Donna Charlevoix
• Kendall/Hunt Publishing Co., Dubuque, Iowa

Material for Which You Will Responsible

• The class is divided into 6 subject areas for
  which lectures are built.
• The lecture subject each day will appear in the
  syllabus.
• Dates of when subjects will be covered are
  estimated in the syllabus now, but will be
  modified as we move ahead or behind the schedule
• Specific text book chapters will be assigned in
  the syllabus. You are expected to read this
  material before class.
• Lectures will be designed to discuss text book
  material, but will not cover all of the material
  presented in the text book. You still are
  responsible for material not covered unless I
  specifically say that you are not responsible for
  certain material. It is your responsibility to
  ask questions to clarify subjects that you do not
  understand.
• Generally, homework questions will be a good
  guide to the questions appearing on the tests.

11
Homework

• A homework will be assigned every other week
• The assignment will be listed on the Lecture
  Slides available on line
• Assignments will consist of
• Problems in the text
• Problems based on Lecture material
• Homework will be handed in electronically

Introducing to Weather and Climate

• Radiation from the sun (mostly in the form of
  visible light) shines on the earth and for the
  most part passes through the atmosphere on to the
  surface
• Sun shining on surface (2/3 water) has two
  effects
• Causes water to evaporate
• Heats the surface, and heat is conducted into the
  air

18
Introducing to Weather and Climate

• In order for the planet to maintain an
  equilibrium temperature, the Earth must radiate
  to space the same amount of heat that it absorbs
  from the sun
• The Earth radiates heat from everywhere
• The planet heats and moistens only where the sun
  shines
• Circulations must form to move heat and moisture
  around, thus causing weather
