Introduction

• Records are kept of weather in different areas of
  Canada
• The records illustrate changes and patterns over
  an extended period of time
• Climate is weather conditions of a place averaged
  over a long period of time
• Coastal regions have different climates from
  inland regions

The Currents

• Two major ocean currents affect Atlantic Canadas
  climate
• Currents act as rivers within the ocean,
  transporting much more water than the biggest
  rivers on land
• The Labrador Current brings cold and icy waters
  southward from the Arctic
• The Gulf Stream brings water from the warm
  southern ocean, as it travels northward
• The water from the Gulf stream warms and moistens
  the air above it, and opposite for the Labrador
  current
• When the cool air meets the Gulf streams warm
  air, it produces heavy dense fog among the four
  Atlantic provinces.

The Currents (contd)

• The Labrador current is so cold that it causes a
  few weeks of bitter winter weather for Atlantic
  provinces, especially Newfoundland and Labrador,
  and it travels around the provinces eastern
  shores
• The cold water starts to freeze the surface of
  the ocean near the coast of Labrador
• The cold water forms a layer of slob, that
  resembles slushy ice
• The ice hardens into ice flows, or long flat
  pieces of ice, and then travels southward.
• The Labrador current also carry icebergs from the
  Arctic and Greenland, as the icebergs drift into
  the current toward Newfoundland and Labrador.
• The Labrador current cools Labradors coast
  year-round

Analysis- Climate Factors

• Ocean Currents- the Labrador Current from the
  Arctic brings cool water and the Gulf Stream
  brings warmer air from the south. The temperature
  of an ocean current affects the temperature pf
  the air that travels above it. The ocean currents
  results in dense fog
• Air Masses- The air mass originates over the
  ocean and contains moisture from the water. When
  the air passes over the land, there is
  precipitation caused by the moisture in the air.
• Nearness to water- The water has a moderating
  effect on the temperature, and produces mild
  temperatures compared to the rest of Canada.
• Latitude- Distance from the equator is an
  important factor affecting Atlantic Canadas
  climate. Since Atlantic Canada is close to the
  North Pole it receives the suns rays at an angle,
  rather than straight on, as the equator
  experiences direct rays of light

Conclusion

• The Labrador current, and The Gulf Stream effects
  the Climate of Atlantic Canada significantly, as
  does air masses, the provinces nearness to water
  and the latitude of Atlantic Canada.
