All Flashcards
Define atmospheric convection cell.
Loops of rising & 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.
Define Ferrel Cell.
Convection cell from 30° to 60° latitude.
Define Polar Cell.
Convection cell from 60° to 90° latitude.
Define Trade Winds.
Winds blowing from 30° latitude toward the equator.
Define high pressure.
Sinking air creating higher pressure at the surface.
Define low pressure.
Rising air creating lower pressure at the surface.
What is the effect of uneven solar radiation?
Temperature differences across the Earth, driving atmospheric and oceanic circulation.
What is the effect of the Coriolis effect on global wind patterns?
Deflection of winds, creating distinct patterns like trade winds and westerlies.
What is the effect of high pressure?
Sinking air, clear skies, and dry conditions.
What is the effect of low pressure?
Rising air, cloud formation, and precipitation.
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.
