The horizontal axis is the latitude from 90 degrees to 0 degrees latitude. The vertical axis shows the rate of precession in degrees per hour; positive for clockwise precession, negative for counterclockwise precession (the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Coriolis_effect\">Coriolis<\/a> effect seems to have a minor role).
