8U4L3b Air Pressure & Weather Introduction

8.MS-ESS2-5. Interpret basic weather data to identify patterns in air mass interactions and the relationship of those patterns to local weather.

There are 4 Types of Weather Fronts

Warm Front

The boundary between two air masses where a warm air mass is replacing a cold air mass

Cold Front

The boundary between two air masses where a cold air mass is replacing a warm air mass

Stationary Front

a pair of air masses, neither of which is strong enough to replace the other; moves very slowly

Occluded Front

a combination of two fronts that forms when a cold front catches up and overtakes a warm front
