What is the primary difference between a warm front and a cold front?

A warm front involves warm air replacing cold air, while a cold front involves cold air replacing warm air.

How does the density of air masses affect the movement and behavior of warm and cold fronts?

Cold air is denser than warm air, causing it to sink and push under warm air in cold fronts. Warm air is less dense, causing it to rise over cold air in warm fronts.

Describe the cloud formation process associated with a warm front.

As warm, moist air rises over the colder air in a warm front, it cools and condenses, forming clouds that gradually thicken and lower as the front approaches.

What type of weather is typically associated with the passage of a cold front?

A narrow band of heavy rain and thunderstorms, followed by clearing skies and cooler temperatures.

Explain how an occluded front forms and why it has characteristics of both warm and cold fronts.

An occluded front forms when a cold front catches up to a warm front, lifting the warm air mass off the surface. It has characteristics of both because it involves both warm air rising (like a warm front) and cold air displacing warmer air (like a cold front).

Guided Notes

3 key concepts

1
A weather front is the boundary between two air masses with different temperature and humidity.
2
Warm fronts are represented on weather charts as solid lines with semicircles, while cold fronts are shown as solid lines with triangles.
3
Occluded fronts occur when a cold front catches up with a warm front, lifting the warm air and creating weather with characteristics of both warm and cold fronts.
