Workshop #5, May 30-31, 2002

Washington, D.C.


The fifth AOMIP Workshop occurred over two days in late May, 2002, in Washington, DC. The workshop actually consisted of two separate events. On the first day, AOMIP participants were convened to discuss project status and future goals. On the second day, AOMIP participants presented their recent modeling work at the AGU Spring Meeting (special session on Global Climate Change).

Progress Reports

Mike Steele & Jinlun Zhang (UW)
It was reported that an updated version of the PHC atlas is currently being prepared. The revised atlas will correct a deficiency in an earlier version of the atlas with respect to waters near the freezing point being incorrectly represented, particularly in the area of Hudson's Bay and the Canadian Arctic Archipelago. The revised atlas will be released in time for use in the AOMIP coordinated 1948-1979 spin-up experiment.

Sirpa Hakkinen (GSFC)
Analysis and intercomparison of the Barents Sea throughflow and sea-ice cover using various AOMIP models was carried out in the past year. A poster describing the results were presented at the spring AGU special session.

David Holland & Petteri Uotila (NYU)
An AOMIP postdoctoral researcher (Petteri Uotila) was hired at NYU this past year. The maintenance and development of the AOMIP website was continued on an NYU host machine. An intercomparison analysis of the seasonal variation of the kinetic and potential energy budgets of various AOMIP models was carried out. A poster describing the results was presented at the spring AGU special session.

Jia Wang (IARC)
Results from a coupled ice-ocean Arctic model were presented. An investigation into quasi-decadal oscilations in the Arctic ice-ocean system was discussed. A poster and oral presentation describing the results was presented at the spring AGU special session.

Wieslaw Maslowski (NPS)
Preliminary results from the intercomparison of an 18-km and 9-km horizontal resolution coupled ice-ocean Arctic models was reported on. The higher resolution model indicated a better representation of the level of eddy-kinetic energy in a region where observations are available, the Labrador Sea.

Rudiger Gerdes, Cornelia Koeberle, & Michael Karcher (AWI)
A report on modeling the variability of the freshwater storage in the Artic ice-ocean system and its transport to the GIN seas was reported on. A study of the exchange of Atlantic waters between the GINS Sea and the Arctic was presented. Also work on comparing the simulation of sea-ice in differnt Arctic ice-ocean models was presented. A poster and oral presentation describing all theses results was given at the spring AGU special session.

Nadja Steiner & Greg Holloway (IOS)
The intercomparison of freshwater and heat storage in various AOMIP models was reported on. It was noted that the use of the OMIP forcing might produce a cold-bias in the upcoming AOMIP coordinate experiement. A poster describing the results was presented at the spring AGU special session.

Andrey Proshutinsky (WHOI)
The overall management and progress of the AOMIP project was reported on. A highlight was the publication this past year of a peer-reviewed article in EOS describing the first results from the AOMIP project. An oral presentation describing the status and results achieved during the past year was given at the spring AGU special session. Furthermore, progress made in the intercomparison of the performance of AOMIP models with respect to their ability to simulate observed seasonal variation in coastal sea-level was presented. A poster describing the sea-level intercomparison results was presented at the spring AGU special session.

Day 2 - May 31, 2002


  • Poster Session (08:30 am - 12:00 noon)
  • Oral Session (13:30 pm - 17:00 pm)


The Arctic is an important component of the global climate system. This fact is highlighted by global climate model simulations that consistently show the Arctic to be one of the most sensitive regions to climate change. Although essential to interpreting model simulation results and their implications for climate variability, an identification of the differences among models and model systematic errors in the arctic has yet to be achieved. For this reason, a set of symbiotic model intercomparison projects are currently addressing different aspects of the Arctic climate system, for example, the Sea Ice Model Intercomparison Project (SIMIP), the Arctic Regional Climate Model Intercomparison Project (ARCMIP), the Arctic Ocean Model Intercomparison Project (AOMIP), etc. Collectively, all these intercomparison projects reflect a significant research effort towards improving the representation of the Arctic region in global climate models. The goal of this session is to bring together arctic researchers involved in the model intercomparisons and model validation studies in order to exchange ideas and methods of model improvement based on the intercomparion approach. It is our hope that this session will serve as a catalyst for researchers from different fields, fostering a synthesis of major aspects of arctic climate system modeling.
