The 2004 Workshop on the Solution of Partial Differential Equations on the Sphere will be held July 20-23, 2004, hosted by Frontier Research System for Global Change, Yokohama, Japan. The location is the same area where the Earth Simulator resides: http://www.jamstec.go.jp/frsgc/eng/map_e.html

A fundamental issue in climate and weather modeling is the dependence of errors in general circulation models on their basic dynamical cores. To advance the state-of-the-art for numerical weather prediction and climate simulation, this organization encourages research on numerical algorithms and solution methods for partial differential equations (PDEs) posed in a spherical geometry. We also foster the development of tests and diagnostics for atmospheric and ocean model dynamical cores.

The development of new methods in spherical geometry and how these eliminate shortcomings of current methods, application to the shallow water equations and to complete baroclinic models are the current focus.

Topics of interests:

1. Advection schemes:
monotone advection scheme, TVD methods, flux correction methods, and Eulerian and semi-Lagrangian methods applied to three dimensional aroclinic equations, two dimensional shallow water equations, and pure transport in spherical geometry and/or plane geometry.

2. Discretization method:
spectral transformation methods, gridpoint methods using polyhedral grid ystems including geodesic grid systems as well as the latitude-longitude grid system, spectral element methods, and alternative discretizations.

3. Comparison study of methods:
the presentation of results from current or new methods, and the comparison of these methods with standard schemes.

4. Computational performance:
the performance of current methods of choice and new methods on parallel computers, including limitations associated with algorithm and computer design are appreciated; implementation details for distributed and shared memory architectures as well as discussion of attendant difficulties are
of interest; characteristics of parallel computers that may affect computational algorithms, in particular, future design aspects could be considered as they might affect algorithm implementation.

5. Discussion and proposal of test cases:
the development and evaluation of new test methods, in particular, the potential ability of test cases to evaluate dynamical cores of atmospheric and
ocean general circulation models; reviews of experience with existing test cases, including what has been learned and what can be learned from such tests, and the introduction of additional test cases and experience with them.

6. Global non-hydrostatic models:
the development of global models based on the non-hydrostatic equations as well as the hydrostatic ones; now that recent computer facilities enable us to perform very high-resolution simulation over the globe, we are in a period of transition of the choice of the equations system.
