8.10B Understanding Weather Patterns Flashcard-Mastery

Front

What is the polar jet stream?

Back

A fast-flowing air current in the atmosphere that influences weather patterns by separating cold polar air from warmer air.

Front

What type of weather is associated with a high-pressure system?

Back

Clear and sunny skies, typically with stable weather conditions.

Front

What happens to temperature and weather when a cold front moves into an area with warm air?

Back

The temperature decreases, and there may be heavy rain or thunderstorms.

Front

What is a low-pressure system typically associated with?

Back

Cloudy skies and precipitation.

Front

How does the jet stream affect weather patterns?

Back

It separates warm and cold air masses, influencing storm paths and temperature changes.

Front

What are the characteristics of a cold front?

Back

A boundary where a cold air mass pushes into a warm air mass, often leading to thunderstorms and a drop in temperature.

Front

What is the role of humidity in weather patterns?

Back

Humidity affects precipitation levels and can influence temperature and storm development.

Front

What type of weather is likely to occur at location marked X in a polar jet stream map?

Back

Warm and wet weather.

Front

What is the significance of atmospheric pressure in weather forecasting?

Back

Changes in atmospheric pressure can indicate weather changes, such as the approach of a storm or clear skies.

Front

What weather conditions are expected when a warm front approaches?

Back

Gradual temperature increase, often leading to overcast skies and light rain.
