Wind
Wind is the large-scale movement of air masses driven by pressure differences, temperature gradients, and planetary rotation. Understanding wind patterns and dynamics is essential for terraforming as winds distribute heat, moisture, and atmospheric gases across planetary surfaces.
Physical Mechanisms
Pressure Gradients
- High to low pressure fundamental driving force
- Pressure gradient force creates initial air movement
- Isobars lines of equal pressure guide wind direction
- Pressure systems cyclones and anticyclones
Coriolis Effect
- Planetary rotation deflects moving air masses
- Right deflection in Northern Hemisphere
- Left deflection in Southern Hemisphere
- Geostrophic balance pressure and Coriolis forces
Temperature Differences
- Solar heating creates thermal gradients
- Land-sea contrasts daily temperature cycles
- Latitudinal gradients equator to poles
- Seasonal variations orbital changes
Global Wind Patterns
Hadley Circulation
- Equatorial rising heated air ascends
- Poleward flow upper atmosphere movement
- Subtropical descent air sinks at 30° latitude
- Surface return trade winds toward equator
Mid-Latitude Westerlies
- Prevailing westerlies 30° to 60° latitude
- Storm tracks cyclone movement paths
- Jet streams high-altitude fast-moving winds
- Weather systems frontal boundaries
Polar Easterlies
- Cold polar air dense air masses
- Easterly flow 60° to 90° latitude
- Polar front boundary with westerlies
- Arctic/Antarctic circulation patterns
