How do orographic lifting and frontal wedging act to force air to rise?

Question

?

Answer 1

Orographic is a term for a topographic barrier, such as a mountain. Air cannot move through it, which gives it no option but to move upwards.

Frontal is the obvious term for a weather front. One type of air is lifted up and over another type of air because both do not mix so easily. For example, a cold front is the boundary between cold, dry air and warm, moist air. Warm air lighter than cold air, which causes it be forced upward.

Answer 2

Orographic lifting: Air is forced/pushed upward by the air which is behind it.

Frontal wedging: When masses of warm and cold air collide producing a front. The cooler/denser air acts as a barrier over which the warmer/less-dense air rises.

Answer 3

In an orographic lifting,winds are forced to rise on the windward side of a mountain barrier.The Western ghats in India which block the south-west monsoon winds and force them to rise shedding most of the moisture as heavy rain on the windward side is an example.Anabatic wind is also an example.

In a warm front,the moving warmer air is forced to flow upwards over the cold wedge below.In a cold front warmer air is displaced and and forced up by the moving colder air mass.
