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.
Define atmospheric convection cell.
Loops of rising and sinking air driven by temperature differences.
What is the Coriolis Effect?
Apparent deflection of moving objects due to Earth's rotation.
Define Hadley Cell.
Convection cell from 0° to 30° latitude where warm, moist air rises at the equator and descends as dry air around 30°.
Define Ferrel Cell.
Convection cell from 30° to 60° latitude, driven by Hadley and Polar cells; air rises at 60° and sinks at 30°.
Define Polar Cell.
Convection cell from 60° to 90° latitude where cold, dense air sinks at the poles and warmer air rises around 60°.
Define trade winds.
Winds that blow from the high-pressure zones at 30° latitude toward the equator.
Define high pressure.
Air is sinking, creating higher pressure at the surface.
Define low pressure.
Air is rising, creating lower pressure at the surface.
