upward_northward_momentum_flux_in_air_due_to_nonorographic_gravity_waves "Upward northward" indicates the ZY component of a tensor. Momentum flux is dimensionally equivalent to stress and pressure. It is a tensor quantity. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. "Northward" indicates a vector component which is positive when directed northward (negative southward). "Upward" indicates a vector component which is positive when directed upward (negative downward). 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. "Nonorographic" gravity waves refer to gravity waves which are not generated by flow over orography.
