First circular :
The 2006 Workshop on the Solution of Partial Differential Equations on the Sphere will be held in June 26-29, 2006 and hosted by the Naval Research Laboratory located in Monterey, California USA.

Purposes:

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 schemes, TVD methods, flux correction methods, and Eulerian and semi-Lagrangian methods applied to three dimensional baroclinic equations, two dimensional shallow water equations, and pure transport in spherical geometry and/or plane geometry.

2. Discretization methods:
spectral transform methods, gridpoint methods using polyhedral grid systems such as icosahedral and cubed-sphere systems as well as the latitude-longitude grids, spectral element methods, discontinuous Galerkin 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; summaries of experiences 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 experiences with them.

6. Global hydrostatic and non-hydrostatic models:
the development of global models based on the hydrostatic and non-hydrostatic equations; 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.

Abstract Submission:

Please email your name, the name of your institution
the title of your talk and text of your abstract in plain text or LaTex format to:
pde2006@nrlmry.navy.mil
Small figures ( less than 1MB ) formatted by JPEG, EPS, and PDF can be acceptable.
We will confirm receipt of the abstract within 2 weeks after receiving it. If you do not hear from us then please let us know right away.

Accommodations:

We have reserved a block of rooms at the Portola Plaza hotel under the conference name PDEs on Sphere 2006.
To make a reservation simply call the hotel at 1-866-711-1534 or send an email to reservations@portolaplazahotel.com. Make sure to state your arrival and departure dates and the name of the conference (PDES on the Sphere) organized by the Naval Research Lab. The conference rate is $103 per night.
We highly recommend making your reservations as early as possible as this block of rooms can only be held until May 26, 2006. The Portola Plaza is also the conference venue and they are offering all participants the US government per diem rates which are very reasonable.
For those of you coming from abroad note that the conference can only guarantee the $103 per night rate for the dates June 25-30. So if you need a room for June 24th please contact one of the following hotels (they are listed by price and by proximity to downtown Monterey):

Munras Lodge ($160/night), Phone: 1-800-709-2801

Clarion Hotel ($170/night), Phone: 1-800-821-0805

Quality Inn ($170/night), Phone: 1-800-361-3835

Comfort Inn ($180/night), Phone: 1-888-970-7666
