The phrase \"component_derivative_of_X\" means derivative of X with respect to distance in the component direction, which may be \"northward\", \"southward\", \"eastward\", \"westward\", \"upward\", \"downward\", \"x\" or \"y\". The last two indicate derivatives along the axes of the grid, in the case where they are not true longitude and latitude. A positive value indicates that X is increasing with distance along the positive direction of the axis. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name \"upward_air_velocity\")."@en ; skos:exactMatch , , ; skos:note "accepted"@en ; skos:prefLabel "Eastward derivative of northward wind"@en ; skos:related .
