Climate
The long term pattern of weather for a place averaged for a long period of time
Compass bearing
Degrees on a compass measured in clockwise direction from 0N to 360
Conventional precipitation
Formation of precipitation due to surface heating of the air at the ground surface. If enough heating occurs the mass of the air begins to rise expand and ease. When sufficient cooling has taken place precipitation occurs
Season-summer
Where-prairies
Frontal precipitation
When 2 air masses converge/meet
1 is usually warm and moist and the other cold and dry
The leading edge of the cold air mass acts as a wall and causes the warm air mass to be lifted
The lifting causes the warm air mass to cool (due to expansion)
Season-all year *mostly summer
Where-Ontario and eastern Canada
Relief precipitation
Due to mountain barriers
When an air mass rises to cross a mountain barrier
Winds carrying moisture are forced up the side of mountain. As they move up the mountain side they cool down and the moisture condenses into clouds. Rain occurs on windward side (lush vegetation). The dry winds continue over the mountain where little rain occurs as the wind las lost its moisture and its dry
Season-winter Max
