Aim #32: How is climate influenced by different factors?

*Do Now:

1) If you could live in any climate in the world, where would it be (describe in detail)? Why would you want to live in that climate (i.e., why is that climate appealing to you, what activities would you like/be able to to participate in, etc.)?

Climate•Average weather conditions of an area from year to year

•Describes weather patterns

Factors That DescribeClimate

•1. Average Temperature

•Average monthly & yearly temp

•2. Temperature Range• Amt of temp change during the year• Highest temp – Lowest temp

•3. Average precipitation =• AAverage amount of rain, snow,

sleet, hail that falls in an area in a year

Factors That determineClimate

•1. Latitude

•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

Climate

•Ocean has little affect on climate

•Steep temperature differences

MaritimeClimate

•Strongly influenced by ocean

•Milder•Cooler summers,

warmer winters•Daily temp vary less

Local climate

• Areas where climate is affected by local conditions

• Affected by altitude, large lakes, forests (Why?)– (slow down winds)
