The geostrophic wind vector V_{g} is given below
in various forms, where ρ is density, k is the unit vector in the
vertical direction, f is the Coriolis parameter and Φ is the
geopotential height.

**
**

V_{g} = k×((1/ρf)∇p

in Euclidian coordinates

####

V_{g} = (1/f)∇_{p}Φ

in isobaric coordinates

V_{g} = -(1/f)∂Φ/∂n

in natural coordinates, where n denotes a normal to stream flow.
