Stone, P.H., 1974: The meridional variation of the eddy heat fluxes by baroclinic waves and their parameterization. J. Atmos. Sci., 31, 444-456, doi:10.1175/1520-0469(1974)031<0444:TMVOTE>2.0.CO;2.

The meridional and vertical eddy fluxes of sensible heat produced by small-aplitude growing baroclinic waves are calculated using solutions to the two-level model with horizontal shear in the mean flow. The results show that the fluxes are primarily dependent on the local baroclinicity, i.e., the local value of the isentropic slopes in the mean state. Where the slope exceeds the critical value, the transports are poleward and upward; where the slope is less than the critical value, the transports are equatorward and downward.

These results are used to improve an earlier parameterization of the tropospheric eddy fluxes of sensible heat based on Eady's model. Comparisons with observations show that the improved parameterization reproduces the observed magnitude and sign of the eddy fluxes and their vertical variations and seasonal changes, but the maximum in the poleward flux is too near the equator. The corresponding parameterizations for the eddy coefficient describing the transport of any conserved quantity are given.
