•
Average
weather
Climate
conditions of an area from
year to year
• Describes weather
patterns
•
1.
Average
Temperature
Factors
• Average monthly & yearly
That
temp
Describe
Climate
• 2. Temperature Range
• Amt of temp change during the year
• Highest temp – Lowest temp
• 3. Average precipitation =
• Average amount of rain, snow, sleet,
hail that falls in an area in a year
Factors • 1. Latitude
That
determine
Climate
• Low latitude =
– Warmer climate (direct sun rays)
– More precipitation
• High latitude =
– Colder climate (indirect sun rays)
• 2. Altitude =
– Alt increases  temp decreases
• 3. Ocean currents = affect temp
along coast
• Near cold currents  cooler temp
• Near warm currents warmer
temp
• 4. Mountains
• Windward side = facing wind
• Leeward side = away from wind
(warmer)
• Air passes over windward side
• Rises & cools condenses  rain
• Moves down leeward side 
warmed
• 5. Volcanic eruptions = dust
• 6. Greenhouse gases (CO2, methane,
water vapor)
Pollutants
Enter air
Can affect:
Continental • Ocean has little affect on
climate
Climate
• Steep temperature
differences
Maritime • Strongly influenced by
ocean
Climate
• Milder
• Cooler summers, warmer
winters
• Daily temp vary less
• Areas where climate is
Local
affected by local conditions
climate• Affected by altitude, large
lakes, forests (Why?)
– (slow down winds)
