Title: Climate and Weather


1
Climate and Weather
  • SOL WG.2a

2
Climate
  • Climate is the condition of the atmosphere over a
    long period of time.

3
Think!
  • What is the difference between a desert and a
    tropical rainforest?
  • What is the difference between Antarctica and a
    desert?

If you said temperature and rainfall
(precipitation) you are right!
4
Climate
  • Three characteristics of climate are
  • Temperature
  • Precipitation
  • Seasons

5
Think!
  • Why do some places get more or less rain?
  • Why are some places hot and some places cold?
  • Why do some places have seasons that are equal in
    length and some places dont?

6
Climate
  • Four factors or elements that affect climate are
  • Latitude
  • Wind Currents
  • Proximity to Water
  • Elevation

7
Wind Currents
  • Wind and ocean currents distribute the suns heat
    through convection, the transfer of heat in the
    atmosphere through upward motion of the air.

8
Proximity to Water
  • Areas near the ocean have a milder winter and a
    cooler summer.
  • Ocean currents are like rivers in the ocean.
    Warm water flows away from the equator and cold
    water flows toward the equator.

9
Proximity to Water
  • Some important ocean currents are
  • The North Atlantic Drift - This ocean current
    warms Western Europe.
  • The East Australian Current

11
Elevation
  • Elevation influences temperature. As you go up
    in elevation the temperature becomes colder
    because the atmosphere is thinner. Areas with
    very high elevations can have vegetation similar
    to the arctic.

12
Climate Zones
  • Climate zones are classified by temperature and
    precipitation.

13
Climate Zones
  • Low Latitudes - Tropical Wet and Tropical Wet and
    Dry.
  • Middle Latitudes - Mediterranean, Humid
    Subtropical, Humid Continental, Marine West
    Coast.
  • High Latitudes - Subarctic, Tundra, Icecap
  • Varies - Semiarid, Arid, Highland

15
Deserts
  • Deserts are based on precipitation. There are
    hot and cold deserts. Some hot deserts are The
    Sahara, The Namib, The Atacama, and The Gobi.

16
Tropical Grasslands
  • Savanna - Africa
  • Llanos - Colombia and Venezuela
  • Cerrados - Brazil

17
Temperate Grasslands
  • Prairie - The United States and Canada
  • Pampas - Argentina
  • Steppe - Central Asia

18
Yurts, portable houses, on the Mongolian steppe.
19
Cold Grasslands
  • Tundra - The Tundra is a flat treeless plain
    located in the far north on the coast of Alaska,
    Canada, and Russia. The Tundra has short
    grasses, a few shrubs, mosses, and some flowers.
    Underneath the tundra there is permafrost,
    permanently frozen subsoil.

21
Forests
  • Forests near the equator have more broadleaf
    trees and the leaves are larger because the area
    receives more sunlight.
  • Forests in the high latitudes have more
    coniferous trees because they grow better with
    less sunlight.

22
Rainforests
  • Rainforests are found in tropical wet climate
    zones in the low latitudes. What countries do
    you think have rainforests?

A. Brazil - Amazon Rainforest
B. Congo
C. Indonesia
D. Most of Central America

24
Taiga
  • The Taiga is a large coniferous forest that
    covers most of Siberia.

25

26
Middle Latitude Forests
  • Middle latitude forests have a mix of coniferous
    trees and deciduous trees. Deciduous trees are
    broadleaf trees that lose their leaves in the
    winter time.
