Main Question or Discussion Point
I'm trying to get an understanding of the Coriolis effect, and I understand it when the wind moves longitudinally (North-South). Basically, the wind has a certain horizontal component of its velocity due to the rotation of the Earth, and as it moves North or South the rotation of the Earth changes and so the wind's relative horizontal component of its velocity changes. I understand all this, but too many a time I have seen the effect explained, this nuance is completely neglected. Does the Coriolis effect still occur when wind moves horizontally?
