Hello everyone,

Below is an announcement from Bill Large and Steve Jayne about the next 
CCSM Ocean WG Meeting.  Please let me know if you will attend by sending 
me email at lydia@ucar.edu.

CCSM Ocean  Group Meeting
NCAR, Mesa Lab, Fleischmann Building
Wednesday and Thursday, 13 and 14 December 2006

Suggested  Sessions  (Additional Ideas are Welcome):

How can eddy resolving solutions guide eddy parameterizations?

Regional Climate Modeling

HYCOM in CCSM

The Present State of the Coupled CCSM

Science Talks:   Please volunteer for a 10-15 min. presentation of any 
recent results.

Ocean Mixed-Layer Restratification

The mixed layer at the surface of the ocean is often remixed by 
convective and wind events. Between these events, there are dynamical 
processes that allow horizontal density gradients to slump and 
restratify the mixed layer.  In some regions, such as where deep 
convection occurs, this process strongly affects the mixed-layer tracer 
budgets. Processes that occur largely in the mixed layer, e.g., plankton 
biology and air-sea chemical exchange, will also be affected. I will 
discuss some of these dynamical processes, and focus in particular on 
restratification by mixed layer eddies.  Mixed-layer eddies form from 
ageostrophic baroclinic instability, and they populate the submesoscale 
(scales near 10 km and 1 day). I will present a recently developed 
parameterization for the restratification of the mixed layer by these 
submesocale eddies.
