Hazards - Weather Hazards, the atmosphere Flashcards
1
Q
global atmospheric circulation
A
movement of air in the atmosphere
2
Q
insolation
A
- amount of solar radiation (sunlight) an area receives over a specified time
- low latitudes (equator) > high latitudes (poles)
3
Q
why insolation varies with latitude
A
go blurt
4
Q
cells
A
- circular air movement
- spreads surplus energy from equator to poles
5
Q
coriolis effect
A
- earth rotates from w to e = resulting force
- right in northern, left in southern
6
Q
jet streams
A
- fast, narrow bands of air
- forms bc temp gradient between
- cold polar air + sub tropical air = polar front jet stream
- subtropical air + equatorial air = subtropical jet stram
7
Q
effects of seasonal changes
A
- pressure belts & winds move north in summer
- move south in winter
