12th IWMO 2021

12th International Workshop on Modelling the Ocean 2021

The 12th International Workshop on Modeling the Ocean (IWMO) will to take place in Hamburg on June 14-18, 2021.
We invite you to submit abstracts for presentation (oral or poster) at the workshop on all aspects of ocean and coupled air-wave-sea, ice and current-sediment modeling and observational analysis. The submission deadline is APR 15, 2021.


Session Themes

Circulation and Dynamics Ocean circulation changes on various spatial and temporal scales and in most cases these changes occupy a continuum spectrumof scales. This section seeks contributions of numerical, theoretical and observational studies on multi-scaleinteractions such as (but not limited to): eddy vs mean-flow, eddy vs waves, mesoscale vs submesoscale, mesoscalevs subgyre-scale (e.g., oceanic fronts, western boundary currents, and recirculations), and subgyre-scalevs basin-scale circulations.

Coastal Modeling This session invites presentations involving the study of circulation, transport, mass exchange, sediment transport and associateddynamics in estuaries, harbors, shelf and other coastal environments based on analytical, observational andnumerical model analyses.

Air-Sea-Interaction We invite presentations of studies that highlight specific physical processes in the air-sea, air-wave, wave-circulation,wave-ice-sea and air-wave-sea coupled systems. We also encourage presentations of observational and experimentalresearches that provide insights on understanding connections of the air, sea, wave and ice.

Climate Dynamics and Processes Successful simulations and accurate predictions of climate variability require a thorough understanding of the underlyingdynamics of the primary modes that produce the variability. These influential modes include the El Nino-SouthernOscillation, Indian Ocean Dipole, Pacific decadal Variability, Atlantic Multidecadal Oscillation and theAtlantic Meridional Overturning Circulation, and many others. Theoreticians, diagnosticians, modelers andobservationalists are invited to this session to share their new findings of the dynamical processes involvedin the generation and evolution of these climate modes and the strategies for modeling them.

Waves and Turbulence This session is related to ocean surface waves and their dynamics, modelling, applications and interaction with currents.The session aims to provide an overview of all those processes from surface boundary layer to bottom. Observations, modellingand theoretical studies are all welcomed.

Coupled biophysical Ocean Studies This session seeks papers dealing with all aspects of coupled physical-biogeochemical processes in oceans. Observational evidence,numerical and theoretical studies are all welcomed.

Data assimilation and Ocean forecast systems This session seeks papers in various aspects of data assimilation research and ocean forecast systems, including but notlimited to the data management and integration, dynamical model development and calibration, products validationand dissemination, and practical applications.

Numerical Techniques and Approaches in Ocean Modeling The session seeks presentations that test or demonstrate various aspects of numerical ocean modeling. Topics may includenew schemes that reduce numerical errors or improve efficiency of numerical codes, comparisons of differentmodel types or different grids, nesting or parallelization approaches, etc. Techniques for improving modelforcing, boundary conditions or data assimilation methodologies may be of interest as well.

Multi-scale processes Multi-resolution numerical modeling has been increasingly applied in both coastal and global ocean studies. In particular,new-generation ocean models based on unstructured-grids started to draw high attention in the climate researchcommunity due to their ability to resolve multi-scales in a convenient way with low computational cost. Thissection seeks contributions of studies on numerical methods and applications related to multi-resolutionocean modeling. Model applications include, but not limited to, using multi-resolution approaches to studyocean dynamics, interaction between the ocean, atmosphere and cryosphere, and biogeochemical processes inthe ocean.

Conference Overview

The IWMO was first held in 2009 ( https://phyoce.es.ntnu.edu.tw/2009WMO/) with the goal that modelers and observationalists interested in ocean processes and coupling with its surrounding can exchange their latest research and wide-ranging ideas in an intellectually rewarding and relaxing environment. The IWMO focuses on all aspects of ocean and coupled air-wave-sea, ice and current-sediment modeling: processes, analysis and prediction. The earth system is inter-connected on a broad range of temporal and spatial scales, and we welcome coastal, regional and basin-scale studies, as well as interdisciplinary topics. As in the past workshops, we particularly encourage participation from young scientists – graduate students and postdocs – and will again host the Outstanding Young Scientist Awards (OYSA) competition. Selected works of IWMO presentations will be published as a special issue in Ocean Dynamics.
