1. Factors Affecting Climate (in Atlantic Canada)
Latitude
Air masses
Ocean currents
Proximity to water

2. Latitude
Because the earth’s surface is curved, sunshine is more intense in lower latitudes (i.e. closer to the equator).

3. Air masses Continental Arctic Air Mass feels cold and dry
Maritime Tropical Air
Mass feels warm and moist
Maritime Polar Air Mass feels cool and moist
Fronts bring about changes in weather
When cold dry air meets warm moist air we get precipitation

4. Ocean Currents The Gulf Stream brings warmth
The Labrador Current bring cold waters
When warm moist air (G.S.) meets the cold waters (L.C.) it cools forming fog

5. Proximity to Water
Water, and the air over it, heats up and cools down more slowly than land
Areas close to large bodies of water stay cooler in summer and warmer in winter (inland areas are the opposite)
