Block-structured adaptive meshes and reduced grids for atmospheric general circulation models.
Adaptive mesh refinement techniques offer a flexible framework for future variable-resolution climate and weather models since they can focus their computational mesh on certain geographical areas or atmospheric events. Adaptive meshes can also be used to coarsen a latitude-longitude grid in polar regions. This allows for the so-called reduced grid setups. A spherical, block-structured adaptive...
متن کاملEstimation and Analysis of Caspian Region's Future Rainfalls by Using General Atmospheric Circulation Models.
In recent years, the severe fluctuations in precipitation have affected various parts of the country. On the southern coasts of the Caspian Sea, precipitation as one of the important climatic parameters has undergone changes due to global climate change. In the present study, we tried to evaluate the effect of climate change on rainfall in this region by applying a suitable model. In this study...
متن کاملStable difference methods for block-structured adaptive grids
The time-dependent Schrödinger equation describes quantum dynamical phenomena. Solving it numerically, the small-scale interactions that are modeled require very fine spatial resolution. At the same time, the solutions are localized and confined to small regions in space. Using the required resolution over the entire high-dimensional domain often makes the model problems intractable due to the ...
متن کاملBlock-Structured Adaptive Grids On The Sphere: Advection Experiments
A spherical 2D Adaptive Mesh Refinement (AMR) technique is applied to the so-called LinRood advection algorithm which is built upon a conservative and oscillation-free finite-volume discretization in flux form. The AMR design is based on two modules, a block-structured data layout and a spherical AMR grid library for parallel computer architectures. The latter defines and manages the adaptive b...
متن کاملA Moist Benchmark Calculation for Atmospheric General Circulation Models
A benchmark calculation is designed to compare the climate and climate sensitivity of atmospheric general circulation models (AGCMs). The experimental setup basically follows that of the aquaplanet experiment (APE) proposed by Neale and Hoskins, but a simple mixed layer ocean is embedded to enable air–sea coupling and the prediction of surface temperature. In calculations with several AGCMs, th...
