What is the altitude range for Surface Winds, and how do they move?

The altitude range for surface winds typically occurs below 2000 feet Above Ground Level (AGL), where the winds are influenced significantly by the frictional effects of the Earth's surface. At this lower altitude, winds predominantly move at an angle across isobars, typically around 45 degrees. This behavior is a result of the balance between the pressure gradient force, which moves air from high to low pressure, and the Coriolis effect, which causes winds to turn to the right in the Northern Hemisphere. However, due to surface friction, this turning is not as pronounced as it is at higher altitudes, leading to the characteristic angle of approximately 45 degrees across isobars seen in surface wind patterns.

Understanding this behavior is crucial for interpreting weather patterns and predicting how local conditions may affect flying operations or other weather-sensitive activities. The other choices do not accurately reflect the characteristics of surface winds and their interactions with isobars, making the information about the 45-degree movement the most relevant and correct.
