Call for papers EGU general assembly, Vienna 12 april - 17 april 2015.
Deadline for abstract submission: 7 January 2015

(sorry for multiple postings)

Dear colleagues,

Please consider submitting an abstract to the session :
OS4.4 : Recent algorithmic developments in oceanic models : numerical schemes and test-cases for model assessment

Description :
Ocean/sea-ice simulation models are widely used in realistic contexts for climate studies (coupled to the atmosphere)
and for the study of the atmospherically-forced ocean general circulation, and in more simplified contexts for investigating
isolated processes (e.g. idealized test-cases). Thanks to advances in computational power, those models are now configured
with increasingly higher horizontal/vertical resolution which requires continuous rethinking of numerical methods and modeling
assumptions. The objective of this session is to bring together scientists working on the improvement/development of numerical
kernels of ocean/sea-ice models (and/or simplified models like transport or shallow-water equations), including their synergy
with physical parameterizations.

The scope is on the design, testing, and application of new numerical methods, and the assessment
of methods currently used in existing state-of-the-art models in realistic or idealized configurations.

This includes three main topics

(i) horizontal/vertical discretization techniques adapted to fixed/variable structured/non-structured meshes,
and the associated time-integration techniques,
(ii) the adaptation of numerical methods to physical constraints : monotonic/positive-definite schemes for
passive tracers, the control of numerically-induced mixing, and more generally physics-dynamics coupling issues,
(iii) the development of semi-idealized test-cases and/or realistic configurations to exploring the merits of
different numerical approaches and highlighting successes, deficiencies or biases in model code, approximations or parameterizations.

Conveners :
Florian LemariƩ, Mehmet Ilicak, Sergei Danilov, Thierry Penduff, Laurent Debreu
