Can I differentiate Empirical Orthogonal Functions w.r.t. to space?

15 January 2018 0 7K Report

If I have the EOFs for velocity potential and stream function can I use it to derive EOFs for velocities by differentiating them once w.r.t. space or derive EOFs for divergence or vorticity by differentiating the original EOFs twice w.r.t. space? Is applying an operator like differentiation or integration valid when dealing with empirically obtained spatial modes?
