Mechanical internal boundary layer; lowest height.

This function calculates the lowest height of the mechanical internal boundary layer (MIBL). The MIBL height is calculated based on the distance to the point of roughness change using an empirical relationship described by Bendix (2004, p. 242).

Usage

bound_mech_low(dist)

Arguments

dist: Numeric. The distance to the point of roughness change in meters (m).

Value

Numeric. The height of the boundary layer in meters (m).

Details

The mechanical internal boundary layer (MIBL) is a concept used in meteorology to describe the layer of air that develops after a change in surface roughness. The height of the MIBL is important for understanding the vertical distribution of wind speed and other meteorological variables.

The function uses the formula: $$height = 0.3 \sqrt{dist}$$ where $dist$ is the distance to the point of roughness change in meters.
