Gregory J Tripoli
Born Cleveland, Ohio, 1950
Lived on the shores of Lake Erie until 1966
Became interested in weather for
purposes of forecasting:
– future weather affecting fishing conditions on
the Lake
– Snow sufficient to cancel school
Professional Background?
• Fireman/engineer, Penn Central Railroad,
NYC? (1970-1971)
• Seminole? (BS, MS, FSU, 1969-1974)
• Tiger? (Princeton University, 1974-1976)
• Ram? (CSU, 1976-1987, PhD, 1986)
• Badger (UW professor since 1987)
Teacher and Research Meteorologist
specializing in basic understanding of
convective weather systems through explicit
mathematical modeling of physical processes
Course Goals
• Develop a basic understanding of the
Earth’s 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

Basic Lecture Structure
• 10-15 minute discussion of current
weather, pointing to applications of the
current topic…on 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
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.
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
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
