Factors Affecting Climate
2
Climate vs. Weather Weather is the day to day conditions of the atmosphere. Temperature Precipitation
3
Weather vs. Climate Climate is the daily weather conditions of a place (station) averaged over a long period; generally on a yearly basis
4
Why is there a big difference in climate across Canada?
5
6 Factors That Affect Climate:
Latitude Ocean Currents Wind & Air Masses Elevation Relief Nearness to Water

1. Latitude The farther you are located from equator the less energy you receive Less energy = lower temperature Link

2. Ocean Currents Water closer to the equator is warmer as it absorbs more energy from the sun Water warms/cools the air above it
13
3. Winds and Air Masses Air heated or cooled by land or water
Hot air rises, cold air falls Air moves from high to low pressure = wind Established winds are called Prevailing winds Westerlies
15
4. Elevation As air rises, it expands & cools
Lower air pressure As air cools, it leads to condensation Clouds turn to rain/snow Rate of cooling: 1°C/100m
16
5. Relief Air rises up the windward slope of a mountain, expands & cools When clouds become too heavy, precipitation occurs As cold air descends on the leeward slope, it contracts and becomes warmer. A rain shadow is created as most of the moisture was already released (Relief Precipitation)

6. Nearness to Water The temperature of water changes slowly
Temperature of air & land changes more quickly 2 distinct climates: Continental Climate Great temperature range Less precipitation Maritime Climate Small temperature range More precipitation
