Climate in Georgia
EQ: What is the impact of climate on
Georgia’s growth and development?
What is climate?
• Climate= Weather of a region over a long period of
time
• Weather = Day to day conditions & changes in
atmosphere: hot/cold, wet/dry, clam/stormy,
clear/cloudy (1)
– Occurs day-to-day
• Influences businesses, crops, and everyday life. (2)
Georgia’s Position on Earth
• Latitude 30-35 N
• Longitude 81-85 W
• Our position means we
experience winter in
December, January, and
February.
• Summer in June, July,
and August.
• Transitional seasons in
between due to the
sun’s position in the sky
relative to earth.
Wind & Water Currents
• Georgia is located in the Southeast Region of the
United States
• Wind Current – current of air moving from areas
of high to low pressure (12)
• Both Atlantic Ocean and Gulf of Mexico
influence Georgia (11)
– Bring mild weather and precipitation (11)
– Wind patterns off of these bodies of water affect
weather
– #13  Sailing
Landforms & Water
• Variations in elevation causes changes in both
temperature & precipitation (4)
• The presence of water or mountains can affect local
climate
Temperature
• Influenced by latitude, longitude, and
elevation
• GA is close to the equator = mild climate (3)
– Good for businesses who want to move
headquarters to GA
• Well-defined seasons
• Winters are brief
• #5
Temperature
• GA has 4 distinct seasons:
– Winter
– Spring
– Fall
– Summer
Temperature
• Statewide monthly temperatures vary smoothly
from January to July and lag the seasonal solar
radiation by about a month

– Louisville 7/24/1952
– Greenville 8/20/1983
• Lowest Temperature was -17 degrees F
– CCC Camp F-16 1/27/1940 (NW GA)
Agriculture
• Most of the jobs in Georgia are related to
agriculture.

– 39 inches
– Diamond 1994-95
Water
• 71% of the earth is
covered in water
(14)
• Ocean currents are
caused by: (15)
– Wind / temperature
changes
– Gravity
– And natural events
(earthquakes)
Natural Hazards
• Tornadoes are usually created in a thunderstorm
– Mix of warm/ humid air with dry/cool air (16)
• The Gainesville tornado of April 6, 1935 was one of
the country’s deadliest
– 203 killed
– Around 1600 injured
• Georgia has an average of 29 Tornadoes a year (21)
• Tornado Season = March – May

Hurricanes
• Naming process
– World Meteorological Organization develops list
of names that are assigned in alphabetical order
to tropical storms (which eventually turn into
hurricanes) (18)
– Names can be repeated after 6 years
• Class 5 wind speeds can exceed 156 mph (19)
• CROSS OUT #20
El Nino / La Nina
• El Nino = warmer than normal ocean surface
temperatures (24)
– Floods in some areas / droughts in other
• La Nina = colder than normal ocean surface
temperatures (24)
– Flooding
