- Dan's Flashcards
How does volcanic activity affect climate change?
- Blocks light from reaching surface/being absorbed by greenhouse gases
What is weather?
Daily conditions of the atmosphere
What is climate?
Average weather over 30 years
How does latitude impact climate?
- 90’ North to 90’ South
- Concentrated sunlight at Equator, hotter
- Dispersed sunlight at poles, colder
How does altitude impact climate?
- Rain shadow effect
How does the Gulf Stream impact climate?
- Ocean current from Gulf of Mexico
- Warms mainly SW UK
- Mild Winters
Describe the climate of the UK.
- Temperate
- Seasonal
- Maritime
What is a depression? What are the features?
- Cyclonic weather
- Storms, rainy, wet, cloudy, windy, changeable
- Low pressure, anticlockwise winds
Depression Stage 1
- Cirrus clouds (high)
- Warm front
- Cold air
Depression Stage 2
- Low cloud
- Rain
- Cold air
Depression Stage 3
- Stratus clouds (high)
- Warm air
Depression Stage 4
- Cumulus clouds (thick, low)
- Heavy rain
- Cold air
Depression Stage 5
- Some low cloud
- Clear sky
- Cold air
What is the evidence of climate change? (6)
- Changing CO2 levels
- Ice cores
- Tree rings
- Changing migratory patterns
- Changing sea levels
- Temperature records
What is the greenhouse effect?
- Heat enters atmosphere from Sun
- Some reflected back, some reaches surface of Earth
- Short-wave radiation absorbed
- Long-wave radiation reflected
- Greenhouse gases absorb this + reflect it back
What is an anticyclone?
- High pressure, clockwise winds
What does a summer anticyclone cause?
- Dry
- Settled
- Hot
- Clear skies
- Calm
- Possible thunderstorms
What does a winter anticyclone cause?
- Foggy
- Frosty
- Cold
- Calm
- Settled
- Clear skies
- Dry
