Cold Fronts Flashcards
How does the weather look like on the cold front?
Cold air forces warm air to rise and condensation occurs and colds form
Where is the cold air from
Polar regions
Cold air heavy
Dense=higher up
Temperature on the cold front ?
Cool
Atmospheric pressure on the cold front
Higher ( sill LP!)
Why is the atmospheric higher on the front?
Temperatures are dropping in the air
What does the precipitation look like on the cold front
Heavy rain
Why is there heavy rain on the front
Warm air rising quickly and creates tall cumulonimbus clouds
Why is there cumulonimbus clouds on the front?
Vertical uplift of warm air forces to rise quickly
How does the temperature look like on the cold sector and why?
Cold, cold air from poles
How does the atmospheric pressure look like on the cold sector. Why?
Higher, cold air is more dense
How does the precipitation look like on the cold sector? Why
Clearing
Cold air subdued and is drier
How does the temperature look like on the warm sector. Why?
Warm
Warm air from tropics
What does the atmospheric pressure look like on the warm sector? Why?
Lower
Warm air is less dense
How does the precipitation look like on the warm sector? Why?
Light showers
Warm air rising slowly creates cumulus clouds
Cloud type on the warm sector? Why?
Cumulus
Small clouds from slow rising air
What’s the definition of a cold front?
A boundary between a mass of cold air and mass of warm air. The cold air pushes the warm air up, causing it to cool, condense and rain
