Abstract: The Helmholtz-type equation arises in many areas of fluid dynamics, and, in recent years, there has been a rapid increase in the numerical procedures available for solving the equation. In this note, the various methods ...

Abstract: A one-level primitive equation spectral model has been initialized with hemispheric 500 mb geopotential height and vorticity fields using the Southern Hemisphere GARP data sets for the period 3?12 November 1969 inclusive. ...

Abstract: A global general circulation for mean January conditions has been conducted with a nine-level, wavenumber 15 (rhomboidal) spectral model. A semi-implicit algorithm has been used in the time integration, thereby enhancing ...

Abstract: Results are presented for perpetual January and July general circulation simulations using the Australian Bureau of Meteorology Research Centre global spectral model. Particular emphasis is placed on the impact of changes ...

Abstract: The Coupled Model Intercomparison Project (CMIP) involves study and intercomparison of multi-model simulations of present and future climate. The simulations of the future use idealized forcing in increase is compounded ...

Abstract: A coordinated set of global coupled climate model [atmosphere?ocean general circulation model (AOGCM)] experiments for twentieth- and twenty-first-century climate, as well as several climate change commitment and other ...

Abstract: The Global Land?Atmosphere Coupling Experiment (GLACE) is a model intercomparison study focusing on a typically neglected yet critical element of numerical weather and climate modeling: land?atmosphere coupling strength, ...

Abstract: The 12 weather and climate models participating in the Global Land?Atmosphere Coupling Experiment (GLACE) show both a wide variation in the strength of land?atmosphere coupling and some intriguing commonalities. In this ...
