Whether the transform uses the hydrostatic approximation.
Discussion
Whether the transform uses the hydrostatic approximation.
This value is true for WVTransformHydrostatic, WVTransformStratifiedQG, and WVTransformBarotropicQG, and false for WVTransformBoussinesq. WVTransformConstantStratification takes the value from its isHydrostatic constructor option, whose default is false.
