pvtend.verify_div_additivity

pvtend.verify_div_additivity(u_div: ndarray, u_div_adiabatic: ndarray, u_div_diabatic: ndarray) → float

Verify additive consistency of divergent wind decomposition.

Checks that the independently Poisson-inverted adiabatic and diabatic divergent winds sum to the total divergent wind to machine precision:

max |u_div_adiabatic + u_div_diabatic − u_div|

Parameters:

• u_div – Total divergent component, any shape.

• u_div_adiabatic – Adiabatic divergent component, same shape.

• u_div_diabatic – Diabatic divergent component, same shape.

Returns:

Maximum absolute error of the additive split.
