Study Notes

Air Masses and Fronts

Continental tropical air masses (cT) form over deserts and move northward, bringing clear, dry, hot weather in the summer.
Cold air masses (cP) come from northern Canada, maritime polar air masses (mP) come from the North Pacific Ocean, and maritime tropical air masses (mT) come from the Gulf of Mexico.

Fronts

A front is the place where two or more air masses meet.
When air masses meet, the less dense air mass rises over the denser air mass.
Warm air is less dense than cold air, so warm air masses generally rise above cold air masses.

Types of Fronts

Cold fronts form when a cold air mass moves under a warm air mass, pushing the warm air up and replacing it with cold air.
Cold fronts can move quickly and bring heavy precipitation, and the weather is usually cooler after a cold front passes.
Warm fronts form when a warm air mass moves in over a cold air mass, replacing the cold air as it moves away.
Warm fronts can bring light rain and are followed by clear, warm weather.
Occluded fronts form when a warm air mass is caught between two cold air masses, bringing cool temperatures and large amounts of rain and snow.
Stationary fronts form when a cold air mass and a warm air mass move toward each other but neither has enough energy to push the other out of the way, resulting in many days of cloudy, wet weather.

Forecasting Weather

A weather forecast is a prediction of weather conditions over the next few days.
Meteorologists make weather forecasts using information on atmospheric conditions and special instruments to collect data.
Meteorologists use instruments such as weather balloons to collect weather data and make predictions about future weather conditions.
