Global Atmospheric Circulation Flashcards
What are the Characteristics of a Low Pressure System?
- High Winds
- Rising Air
- Evaporation
What are the Characteristics of a High Pressure System?
- Low Winds
- Falling Air
- No Clouds
Which biomes are found at low pressure?
Rainforests
Which biomes are found at high pressure?
Deserts
What is Global Atmospheric Circulation?
The circulation of air in earths atmosphere
What is wind, where does it come from?
Air Moving from High Pressure to Low Pressure
Think about blowing up a balloon and letting all the air out
High to Low Pressure
What are the Characteristics of Sinking Air?
High Pressure
30 Degrees North South Equator
Outward Winds
What are the characteristics of Rising Air?
- Low Pressure
- 60 Degrees North South
- Winds are inward, towards earth
Where are the cloudiest places on earth?
The Hadley Cells and the Equator
Where is the Ferrel Cell Located?
30-60 Degrees North South
The Northern and Southernmost areas
What happens at the Ferrel Cell?
Wind Pulls up to the poles, carrying moisture causing rain
How is Low pressure achieved
Cold and Hot Air Mixes
This causes low Pressure
Causes the UK’s Wet and Windy Weather
What happens at the Hadley Cell?
Air Rises, causing low pressure
Air flows to the equator leading to a trade wind
Which Biome is found in the Hadley cells
Rainforests, Hadley Cells are near the equator
What is the order of pressure from north to south?
HIGH | LOW | HIGH
