Meteorology 08/04/2008 01:09:00 pressure gradient force air diffusing from high to low pressure [in the horizontal] will be affected by  coriolis force; in the example, the CF is perpendicular to the tangent of the  direction in which the parcel of air moves. L H [hemispherical case] as velocity of a parcel of air increases, coriolis force increases geostrophic wind : wind that blows at a constant speed parallel to isobars [pressure  gradient force is balanced due to coriolis force] geostrophic winds do not exist at the equator because of the lack of coriolis
