1. Solar Radiation
Solar radiation serves as the fundamental driver of atmospheric circulation patterns, which, in turn, are the source of kinetic energy for generating power from moving air. Uneven heating of the Earth’s surface due to variations in solar insolation creates temperature gradients. These gradients manifest as pressure differences, initiating air movement from high-pressure regions to low-pressure regions. This continual process, fueled by the constant influx of solar energy, ensures a perpetual supply of the resource for power generation.
The importance of solar radiation stems from its role in creating persistent global flows. For instance, the Hadley cell circulation, characterized by rising air near the equator and descending air at subtropical latitudes, is a direct result of solar-driven temperature imbalances. Similarly, land-sea breezes, caused by differential heating rates of land and water, exemplify the localized influence of solar radiation on air currents. Without the continuous input of solar energy, these and other atmospheric phenomena would cease, thereby eliminating the primary source of energy for turbine-based electricity generation.
Understanding the connection between solar radiation and air movement has practical significance for site selection and resource assessment.

These processes, encompassing pressure gradients, temperature differentials, and the Coriolis effect, maintain a perpetual cycle of air movement, ensuring a continuous supply of the source. The following facets highlight the key atmospheric processes involved.
- Pressure Gradients and Airflow
Pressure gradients arise from uneven heating of the Earth’s surface. Areas with higher temperatures experience rising air and lower pressure, while cooler areas experience sinking air and higher pressure. Air naturally flows from high-pressure to low-pressure zones, creating movement. This airflow is the direct source of kinetic energy that turbines capture and convert into electricity. The persistence of pressure gradients guarantees that there is always potential to harness this power.
- Temperature Differentials and Convection
Temperature differentials drive convective currents, both locally and globally. Warm air rises, creating vertical air movement and driving atmospheric circulation. The Earth’s equator receives more direct sunlight than the poles, leading to a large-scale temperature difference that drives major flows. These circulations transport heat and maintain a dynamic atmosphere. Turbine placement often targets areas with predictable temperature differentials and associated flows for maximized power generation.
- The Coriolis Effect and Global Flows
The Coriolis effect, caused by the Earth’s rotation, deflects moving air masses. In the Northern Hemisphere, air is deflected to the right, while in the Southern Hemisphere, it is deflected to the left. This deflection shapes global airflow patterns, creating trade winds and prevailing westerlies. These consistent airflow patterns are vital to the reliability of turbine-based power generation. Understanding and predicting these effects is crucial for optimizing turbine location.
