Absolute angular momentum

In meteorology, absolute angular momentum refers to the angular momentum in an 'absolute' coordinate system (absolute time and space). In meteorology, absolute angular momentum refers to the angular momentum in an 'absolute' coordinate system (absolute time and space). Angular momentum L equates with the cross product of the position (vector) r of a particle (or fluid parcel) and its absolute linear momentum p, equal to mv, the product of mass and velocity. Mathematically,
