WebMixing Height. Measured from the surface upward, the height to which relatively vigorous mixing occurs due to convection. Also called mixing depth. Source: … WebIn the atmosphere, assuming a constant water vapor mixing ratio, the dew point temperature (the temperature where the relative humidity is 100%) decreases with increasing height because the pressure of the atmosphere decreases with height.

WebThe morning mixing height is calculated as the height above ground at which the dry adiabatic extension of the morning minimum surface temperature plus 5°C intersects the vertical temperature profile observed at 12:00 Greenwich Mean Time. WebMixing Height. Because turbulent fluxes vary based on surface heating and other factors, the height of the PBL also varies. At night, the height of the PBL decreases dramatically as the stable layer forms. The height of the PBL is called the mixing height, because it is the height up to which the air is well-mixed.
