First off all, I've no knowledge of how all this works. I've only got some common sense of "how things work"... But I've been wondering this for quite a long time now, so maybe you guys can help me.
The question is rather simple: Where does the raindrop come from? And with that I mean: The raindrop that just hit the ground, where did that come from? From the clouds that are right above me, in front of me, or back of me?
So let's say that we've got these 3 possibilities, which one is the most likely one?
The first one, where the rain is traveling with the same speed horizontal as the cloud it came from: (so it came from the cloud directly above me)
The second one, where the rain is traveling faster than the clouds (due to wind?). So that the rain came from the cloud that yet has to pass me.
The third one, (And i do think that this is the right one) is that the rain is falling slower (horizontally seen) than the cloud (because the cloud is lighter). So that the rain that hits the ground came from the cloud that already past me.
An another possibility is that the rain is going left and right, (keeping it 2D for simplicity) because of the different wind regions (in the high clouds, the wind goes from left to right, but lower it goes from right to left).
Is there even an "right" answer for this? Or are there too many variables that could change everything?
And could you please explain it as simple as possible? I've got zero knowledge in this area...
Thank you in advantage!
