Lifting Mechanisms Flashcards
1
Q
convergent lifting
A
air flowing from different directions into same low-pressure area is converging, displacing air upwards
2
Q
Inter-Tropical Convergence Zone
A
- where trade winds meet along equator
- why there are more clouds along equator
3
Q
convectional lifting
A
- unequal heating at surface creating hot spot
- air in contact expands and rises
- rising air adiabatically cools to dew point temp
- happens all summer long
4
Q
orographic lifting
A
- air is foricbly lifted upslope
- stable air forms stratus clouds, unstable can form cumulus
5
Q
windward vs leeward
A
windward: where widn comes from, wet
leeward: where wind goes, dry
6
Q
chinook winds
A
warm downslope winds that bring dry conditions to areas downwind of mountains
7
Q
frontal lifting
A
when cold and warm air interact
8
Q
front
A
leading edge of advancing air mass, place where different temps, densities, and humidities collide
