Record Title : Tendency of Specific Humidity due to Boundary Layer Mixing
CF Standard Name : tendency_of_specific_humidity_due_to_boundary_layer_mixing
Record Description : The phrase "tendency_of_X" means derivative of X with respect to time. "Specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "Boundary layer mixing" means turbulent motions that transport heat, water, momentum and chemical constituents within the atmospheric boundary layer and affect exchanges between the surface and the atmosphere. The atmospheric boundary layer is typically characterised by a well-mixed sub-cloud layer of order 500 metres, and by a more extended conditionally unstable layer with boundary-layer clouds up to 2 km.
