Creating animation patterns

So I basically want to create wind patterns, that last the amount of seconds I want them to last; what I’m meant to do is to create videos that can loop forever and give and effect of continuity, I’m also supposed to do the same with water, same thing, that I give an effect of continuity when the vid loops.

Thanks :3

Your best bet for this is probably going to be texture based. For example, if you find tutorials that show how to make wind blow across a landscape, you will see that for settings of the force they use a texture, which controls the strength of force at any specific position. Since the texture would be tiled in all directions, it should be somewhat loopable. The problem would still lie in making that first and last frame match up, considering how random physics can be.
