| Definition | The surface called "surface" means the lower boundary of the atmosphere. A velocity is a vector quantity. "y" indicates a vector component along the grid y-axis, positive with increasing y. "Geostrophic" indicates that geostrophic balance is assumed, i.e. that the pressure gradient force and the Coriolis force are balanced and the large scale fluid flow is parallel to the isobars. "sea_level" means mean sea level. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. surface_geostrophic_sea_water_y_velocity_assuming_sea_level_for_geoid is the variable part of surface_geostrophic_sea_water_y_velocity. The assumption that sea level is equal to the geoid means that the stationary component of ocean circulation is equal to zero. | |
