Response of a Strongly Eddying Global Ocean to North Atlantic 
Freshwater Perturbations

The Atlantic ocean circulation, in particular its Meridional
Overturning Circulation (MOC), is sensitive to the surface
freshwater flux. In this presentation we show results on the
differences between the (decadal time scale) response of a
coarse-resolution (non-eddying) global ocean model and a
fine-resolution (strongly eddying) version of the same model to
a (relatively large) freshwater perturbation due to melting of
the Greenland Ice Sheet. We focus on the effect of the
freshwater anomaly on convection, watermass transformations
and the basin wide circulation.

Henk A. Dijkstra is professor of Dynamical Oceanography at the 
Institute for Marine
and Atmospheric research Utrecht (IMAU) within  the Department of 
Physics and Astronomy
of Utrecht University,  the Netherlands. After graduating in applied 
mathematics at the
University of Groningen in 1984, he worked during his Ph.D. (in 
Groningen) on a Spacelab
experiment involving Marangoni convection under  microgravity 
conditions. He continued with
this research at the Department of  Chemical  Engineering at Cornell 
University during the
period 1988-1990. Since 1990 he works at Utrecht University mainly on 
the  stability of the
ocean circulation and on the physics of climate variability.  He is 
author of the books
"Nonlinear   Physical Oceanography" (Springer,  2e edition  2005), 
"Dynamical  Oceanography"
(Springer,  2008) and "Nonlinear Climate  Dynamics"  (Cambridge 
University Press, 2013).
Since 2002, he is a member of the Dutch Royal Academy  of Arts  and 
Sciences (KNAW). In
2005, he received the Lewis Fry Richardson medal from  the  European 
Geosciences Union
and in 2009 he  was elected a Fellow of the Society for Industrial and 
Applied
Mathematics (SIAM).
