Coriolis Force Question

  1. Sep 8, 2012 #1
    I read that in the northern hemisphere the Coriolis force is always 90 degrees to the right of the vector of motion in the rotating frame. That is, driving from SF to NY there is a force to the south, driving from NY to SF there is a force to the north. OK, pseudoforce, whatever. I don't understand. Anyone have a simple explanation for the nudnik?

    Aha.

    When viewed from a stationary point in space above, any land feature in the Northern Hemisphere turns counter-clockwise, and, fixing our gaze on that location, any other location in that hemisphere will rotate around it the same way.

    Now I get it.
