processes that lift air Flashcards
1
Q
what are the processes that lift air?
A
orographic lifting
frontal lifting
convergence
localized convective lifting
2
Q
what is orographic lifting?
A
-as air parcels move over land, they follow the terrain
-orographic lifting occurs when air is forced to rise over a mountainous barrier
3
Q
what is frontal lifting?
A
warmer, less-dense air is forced over cooler, denser air
4
Q
what is convergence?
A
a pileup of horizontal airflow that results in upward movement
-air parcels from different directions meet air will be lifted
5
Q
what is localized convective lifing?
A
unequal surface heating causes localized pockets of air to rise because of their buoyancy
