All Flashcards
Significance of uneven solar radiation?
Drives atmospheric & oceanic circulation patterns.
Explain heat transfer importance.
Uneven heating drives air & water movement, affecting climate.
Role of convection cells?
Redistribute heat from equator to poles.
How does pressure affect wind?
Wind flows from high to low pressure areas.
Coriolis Effect impact?
Deflects wind & ocean currents, influencing global patterns.
How does Earth redistribute heat?
Moving warm air towards the poles and cold air towards the equator.
What drives Ferrel Cells?
Driven by the movement of Hadley and Polar cells.
Why does uneven solar radiation occur?
The Earth's tilt causes the equator to receive more direct sunlight than the poles.
How does Earth redistribute heat?
Through atmospheric and oceanic circulation, moving warm air/water towards the poles and cold air/water towards the equator.
What drives atmospheric convection cells?
Temperature differences caused by uneven solar radiation.
How does air pressure affect wind patterns?
Wind flows from areas of high pressure to areas of low pressure.
How does the Coriolis effect influence wind direction in the Northern Hemisphere?
It deflects moving objects (like air) to the right.
How does the Coriolis effect influence wind direction in the Southern Hemisphere?
It deflects moving objects (like air) to the left.
What is the relationship between latitude and convection cells?
Hadley cells (0-30°), Ferrel cells (30-60°), and Polar cells (60-90°) are located at different latitude bands.
What happens to air at the equator?
Warm, moist air rises, creating a low-pressure zone.
What happens to air at 30° latitude?
Dry air descends, creating a high-pressure zone.
What is the relationship between pressure and wind?
Air moves from areas of high pressure to areas of low pressure, creating wind.
Steps of Hadley cell formation?
Warm, moist air rises at equator, cools, descends at 30°.
Air movement in Polar cells?
Cold, dense air sinks at poles, warmer air rises at 60°.
Wind direction determination?
Air moves from high to low pressure areas.
