Theme C Part 2 Flashcards
What happens to the temperature when the warm front passes?
Temperatures will increase
Why does the temperature increase when warm front passes?
You move from polar maritime to tropical maritime
What happens to the rainfall when warm front passes?
Period of Light Drizzle
Why is there a light drizzle when warm front passes?
Warm air rises over cold air because it is less dense. This causes the air to cool and condensation occurs. Form nimbostratus clouds(Stratus clouds which bring rain)
What happens to the temperature when cold front passes?
Temperature will decrease
Why does the temperature decrease when the cold front passes?
You move from tropical maritime to polar maritime
What happens to rainfall when cold front passes?
There will be a period of heavy intense rainfall
Why is there heavy intense rainfall when cold front passes?
Cold air undercut warm air forcing it to rise. The air will cool and condensation will occur leading to the formation of CUMULONIMBUS clouds
What are the summer temperature during anticyclone?
Temperatures are high
Why are the summer temperatures high during anticlycone?
no clouds to block suns rays. The sun is high in the sky and days are long so temperature builds out throughout the day
What is the winter temperature during an anticyclone
Temperatures will be low
Why are the winter temperatures during an anticyclone low?
The sun is low in the sky and days are short so heat cannot build no. No clouds to trap the heat at night
Is there rainfall during anticyclone
No
Why is there no rainfall during anticylone?
No clouds because air is sinking due to high pressure. As air sinks it warms, so condensation cannot occur
Define Anticyclone
An area of high pressure
Air is sinking
