세계적으로 연구되고 있는 해양순환모형을 인터넷의 WWW를 이용하여 사용가능한 모형들에 대해서 아는데로 적어보았다. 아직 알려지지 않은 해양 순환모형들도 많이 있지만 여기에 열거하는 모형들은 primitive equation에서부터 quasi-geostrophic에 이르기 까지 다양하게 열거하고 있으며 수직적으로는 level모형에서 layer모형까지, 적용 범위로는 지역적인 것에서 부터 전 지구에 이르기 까지, CPU의 갯수로는 하나에서 부터 다중 프로세서까지 열거하고 있으며 앞으로 계속 새로운 소식을 추가할 예정이다.
The Australian Community Ocean Model (ACOM) is a synthesis of Australian enhancements and additions to the GFDL Modular Ocean Model (MOM). It is a collaborative project between interested ocean researchers in Australia from many organisations. ACOM consists of the latest MOM code and database files as modified by Australian researchers. A number of different grids will become available as new model versions are submitted to the project.
Tthe ACOM1 enhanced tropical grid global model updated so that it is now based on MOM2.0, and with further enhancements. Developed by Andreas Schiller and Peter McIntosh at the CSIRO Division of Marine Research. For further details, see the detailed description of ACOM2.0 . This includes instructions for getting the model going on various computers.
Princeton 대학에서 Blumberg and Mellor (1987)에 의해 개발된 POM과 거의 유사하며 3차원 해양 순환모형이다. The difference is that this model uses an implicit scheme developed by Vincenzo Casulli for solving the gravity wave so that the need for separate barotropic and baroclinic time steps is eliminated. 이 모형은 메일로서만 제공 받을 수 있는데 상기에 적은 주소를 참조하기 바란다.

The RSMAS MICOM group is based in the Division of Meteorology and Physical Oceanography (MPO). An isopycnic coordinate ocean circulation model available in several versions. This is a link to the original MICOM home site at the University of Miami. A User's Manual and Theory Guide for MICOM version 2.6 can be accessed via URL http://www.acl.lanl.gov/CHAMMP/micom.html.
This is the Miami Isopycnic Coordinate Ocean Model that has been done at the University of Minnesota. A version of MICOM that runs on the Cray T3D, SGI workstations, and other workstations on which MPI has been installed. They have developed a message-passing version of MICOM called MP-MICOM that uses SHMEM on the Cray T3D/T3E and MPI on other machines. We also have a shared-memory, multi-threaded version (SC-MICOM) for SMP clusters that uses MPI to communicate between machines and direct shared memory within each machine.
This version of the MICOM model has a Kraus-Turner mixed layer and is bounded by a box comprised of latitude and longitude lines. The coordinates are set using Mercator projection scale factors. It is briefly described in boxmix.notes and contained in boxmix.tar.
MICOM - Global : [ftp://nutmeg.rsmas.miami.edu/bleck/global/]
This is a 127x256 grid point global version of MICOM with all of the appropriate forcing function files.
This version of the Miami model has a Kraus-Turner mixed layer, separate equations for T and S, allows variable bathymetry and irregular coastlines. It comes with a North Atlantic Ocean basin configuration and related appropriate initialization files. It is briefly described in micom.notes and is contained in micom_*.*.tar.

The GFDL Modular Ocean Model (acronym MOM) is a three-dimensional primitive equation general ocean circulation model. The model is intended to be a flexible tool for exploring ocean and coupled air-sea applications over a wide range of space and time scales. The current state of the art in three dimensional z-coordinate primitive equation ocean models at GFDL is MOM 2, which was first released in October 1995. Beta testing of MOM 2 version 2 began during the November of 1996.
This is part of the Ocean Dynamics and Prediction Branch of the Oceanography Division of the Naval Research Laboratory at the Stennis Space Center. The chief project is the Ocean Prediction System, part of a coordinated effort to develop efficient and effective ocean nowcast/forecast systems that are eddy resolving (i.e. resolution of 1/8 deg. or better). This involves developing and validating both basin and global scale thermodynamic ocean circulation models that can run on existing and planned operational computers and realistically depict fronts, eddies, and the upper-ocean thermal structure. Images and movies from various simulations are shown and lists of publications and related activity links are given. They have a model called the Navy Layered Ocean Model (NLOM) available by request.
The NLOM has become the world's first scalable portable ocean model. It will run efficiently and interchangeably on massively parallel computers (distributed memory - CM5, CRAY T3D/T3E, IBM SP2, SGI Power Challenge Array, Convex Exemplar), multi-processor shared memory computers (CRAY YMP/C90/T90, SGI Power Challenge, Convex Exemplar), or scalar computers (single processor workstations). To obtain a copy of the NLOM and related software, e-mail harley.hurlburt@nrlssc.navy.mil
The OCCAM Project aims to build a high resolution (1/4 deg.) model of the world ocean. It is a parallelized model, similar to the FRAM model in the area of basic physics, that runs on a T3D machine at Edinburgh. The site contains various information about the project and some pictures and animations of current results.

OCCAM is a primitive equation numerical model of the global ocean. It is based on the GFDL MOM version of the Bryan-Cox-Semtner ocean model but includes a free surface and improved advection schemes. A regular longitude-latitude grid is used for the Pacific, Indian and South Atlantic Oceans. A rotated longitude-latitude grid is used for the Artic and North Atlantic Oceans, which has its poles on the equator in the Indian and Pacific Oceans. This overcomes the singularity that otherwise arises at the North Pole. A simple channel model is used to connect the two grids through the Bering Strait. The model depths are based on the DBDB5 data set. The model was started from the Levitus annual mean temperature and salinity fields. The surface forcing uses ECMWF monthly mean winds and relaxation to the Levitus seasonal surface temperature and salinity fields. The initial model run for 12 model years will be completed by September 1996.
OPA is an ocean general circulation model in primitive equations developed at the LODYC in France. This site tells a bit about the model and has some pictures of simulations performed with it. There's no info about obtaining the model.
It follows the Navier-Stokes equations with the following assumptions:
- The earth is considered as a sphere
- Thin-shell assumption
- Turbulent closure scheme
- Quasi-Boussinesq hypothesis
- Hydrostatism
- The fluid is uncompressible
Moreover, in order to filter external gravity waves, a "rigid lid" assumption is used.
The Parallel Ocean Circulation Model is a descendant of the Bryan/Cox/Semtner chain of model development designed to run on massively parallel computers like the CM5. This site contains a model description, references, and an online from for obtaining parts of the model output. A complete 10yr model run is available for use : the POCM_4B run covers the period from 1987 through 1996. A new model run (POCM_4C) with daily forcing of heat,freshwater, and winds from ECMWF reanalysis fields for 1979-93 is coming.
Resolution : 0.4 deg X 0.4 deg (the model has the properties of a 1/3-degree model at latitude 33 degrees and the properties of a 1/5-degree model at latitude 60 degrees. The average latitudinal spacing is 1/4 degree.)
The POM is a sigma coordinate, free surface, primitive equation model which includes a turbulence sub-model. It was developed in the late 1970's by Blumberg and Mellor, with subsequent contributions from other people. The model has been used for modeling of estuaries, coastal regions and open oceans. Currently, 287 users from 33 different countries are registered in the POM users group.
The POP model is based on the model of Bryan & Cox but is reformulated to run at 1/6 deg. and 20 levels resolution for a full year of simulation in less than a day of computer time. It is forced at the surface by observed temperature, salinity, and wind stress. It runs on the 1024 node CM-5 and was developed at the Advanced Computing Laboratory at LANL. This site tells a bit about the model and how the output was processed to obtain the pictures and movies available there.
This site has a reduced gravity, quasigeostrophic box model (2-D) for use in studies of idealized geophysical fluid dynamics written by John McCalpin using the FWEB literate programming tool which allows the documentation and program to reside in the same file, either of which can be recovered separately via appropriate processing. The package is in the file qgbox.tar.Z.
The S-coordinate Primitive Equation Model (SPEM) is a finite difference ocean circulation model. It replaces the semi-spectral vertical representation with an s-coordinate that allows better resolution above the thermocline. The model is currently at version 5.1 and we also have an implicit free surface version being constructed, which will be known as version 6.0.
This FTP site contains the SPEM 3.9 model developed by Haidvogel and programmed by Hedstrom. The model uses a semi-spectral Chebyshev polynomial representation in the vertical and finite differences in the horizontal.
The shallow water equations are used as a kernel for both oceanic and atmospheric general circulation models and are of interest in evaluating numerical methods for weather forecasting and climate modeling. The DOE CHAMMP program is interested in the development of new mathematical methods for these problems. This model is a parallel version of the NCAR spectral transform SWM designed for message passing parallel computers using the PICL library for portability. The NCAR spectral transform shallow water model (STSWM) and documentation can be down loaded by clicking on stswm.tar.gz .
