@mk_1: the left image is actually the result. @HeelX: jep, on the GPU. Concerning your missing waves: it's not tweaked at all, just the first results. EDIT: ahh, you where searching for horizontal waves! Well, as you can see on the right site, the complex coefficients of the horizontal waves are blacked out, so this is intended. What do want with waves moving orthogonal to the wind direction?

There are your magnitudes: Have you tried to apply a filter in fourier domain and reconstruct the image? How fast is your implementation? Of course, that was the first thing before I threw the phillips spectrum at it: (right side shows only real component of the complex coeffients, not the magnitude (fault of stupid me two days ago)) Runs with 2.3 ms for a 512x512x64 image with FFT + iFFT. So it's nothing you want to do for a simple filter like a small/midrange blur. EDIT: on a nVidia GTX 560 Ti
