Based on the provided reference, no, dunes are described as being more symmetric.
Dune Shape and Symmetry According to the Reference
According to the information available, dunes tend towards a more symmetric form.
The reference specifically states:
- Dunes are more symmetric in shape with slopes of approximately 20°.
- Their orientations are always more perpendicular than parallel to the dominant wind direction.
This description contrasts with the idea of asymmetry, where one side of the dune would be significantly steeper or longer than the other. While many factors can influence dune shape in nature, the specific reference provided highlights a tendency towards symmetry.
Key characteristics from the reference include:
- Shape: More symmetric
- Slopes: Approximately 20°
- Orientation: More perpendicular to dominant wind direction
This information suggests that the wind interaction described in the reference results in a relatively balanced shape, as opposed to a pronounced asymmetric profile often associated with slip faces on one side.
Summary of Key Points from the Reference
Here are the main takeaways regarding dune shape from the source:
- Dunes exhibit a tendency towards a symmetric shape.
- The slopes of these dunes are noted as being around 20 degrees.
- The direction they face is primarily perpendicular to the main wind direction, rather than running parallel to it.
This perspective focuses on a specific condition or type of dune where symmetry is a defining characteristic mentioned.
