What can cause mechanical turbulence during the sea breeze process?

Mechanical turbulence during the sea breeze process is primarily caused by physical obstructions in the environment, such as rough terrain, which can disrupt the flow of air. When wind encounters elements like sand dunes, trees, buildings, or other uneven surfaces, it creates turbulence as the air is forced to change direction. These obstacles cause friction and eddies, leading to a turbulent mixing of the air, which can be significantly more pronounced in areas with pronounced topographical features.

The presence of rough terrain creates localized disturbances that affect wind patterns, especially when the contrast in temperature between the land and sea stimulates a sea breeze. As warm air rises over the land surface, cooler air from the sea moves in to replace it, and any obstructions within that airflow can lead to increased turbulence.

In contrast, aspects such as cloud cover or temperature at the sea may influence wind conditions but do not create the mechanical disturbances associated with turbulence in the same way that rough terrain does. Wind flowing over flat land also tends to remain more laminar rather than turbulent, as there are fewer disruptions to the airflow. Thus, the presence of rough terrain is a key factor in creating mechanical turbulence during the sea breeze process.
