Question

How is warm front formation different from occluded front formation?

A warm air mass rises above a cold air mass during a warm front, but two cold air masses surround a warm air mass during an occluded front.
Two cold air masses surround a warm air mass during a warm front, but a cold air mass moves against a warm air mass during an occluded front.
A cold air mass moves faster than a warm air mass during a warm front formation, but a cold air mass is pushed upward during an occluded front.
A warm air mass and a cold air mass form a boundary during a warm front, but water condenses between two air masses during an occluded front.

Answer 1

"A warm air mass rises above a cold air mass during a warm front, but two cold air masses surround a warm air mass during an occluded front."

Explanation: In a warm front the warmer air advances and gently overruns the colder air. In an occluded front a faster cold front catches up to a warm front, lifting the warm air off the ground so that colder air lies on both sides of the lifted warm air.
