Some Modeling Stuff

While running George Bryan’s CM1, but I imagine that these will come up in other contexts too. Turbulence Schemes By decomposing the flow into a mean + perturbations and averaging, one obtains the Reynolds-Averaged Navier-Stokes (RANS) equations.  These still contain a perturbation term … Continue reading

Madden-Julian Oscillation

Wikipedia says it’s the largest contributor to intraseasonal (time length 30-90 days) variability in the atmosphere, and manifests as an eastward-propagating, alternating stormy/wet phase and dry phase oscillation.  The MJO is a coupling between the large-scale atmospheric circulation and mesoscale tropical … Continue reading
