May 7th: Peter STONE MIT An inter-hemispheric box model of the meridional overturning circulation: energy constraint vs. diffusivity constraint
Add to my calendar: ICS file or Google
We generalize the Rooth three box inter-hemispheric model of the meridional overturning circulation by replacing his single low-latitude box with two, a surface box and a deep box, separated by a thermocline in which we assume a balance between vertical advection and vertical diffusion. We analyze the behavior of the system with two different … Check the full abstract here

May 21st: Julie DESHAYES WHOI Mechanisms of variability in a convective basin
Add to my calendar: ICS file or Google
The oceanic poleward heat transport and the meridional overturning circulation are strongly affected by what happens in convective basins, where dense water is formed. Interannual variability in the formation and export of dense water is mostly due to changes in the two main drivers: local buoyancy fluxes and the remotely-forced circulation. Their relative contribution is investigated by using an idealized model for a convective basin. …. Check the full abstract here
