dynamic similarity

Airflow or wind characteristics that behave alike in different situations.

For example, a vertical wind profile in one location might have the same shape as a wind profile in a different location, except for differences in depth or wind speed. When such vertical profiles are expressed in terms of dimensionless height and dimensionless wind profile, then the profiles often become a common curve that can be described by a single dimensionless equation.
