RISA Global Multilevel Atmospheric Model Using a Vector Semi-Lagrangian Finite-Difference Scheme. Part I: Adiabatic Formulation
Publisher: American Meteorological Society
Abstract: An adiabatic global multilevel primitive equation model using a two time-level, semi-Lagrangian semi-implicit finite-difference integration scheme is presented. A Lorenz grid is used for the vertical discretization and a ...
Four-Dimensional Variational Data Assimilation Experiments with a Multilevel Semi-Lagrangian Semi-Implicit General Circulation Model
Publisher: American Meteorological Society
Abstract: Four-dimensional variational data assimilation (VDA) experiments have been carded out using the adiabatic version of the NASA/Goddard Laboratory for Atmospheres semi-Lagrangian semi-implicit (SLSI) multilevel general ...
The IITM Earth System Model: Transformation of a Seasonal Prediction Model to a Long-Term Climate Model
Publisher: American Meteorological Society
Abstract: ith the goal of building an Earth system model appropriate for detection, attribution, and projection of changes in the South Asian monsoon, a state-of-the-art seasonal prediction model, namely the Climate Forecast System ...
The NCEP Climate Forecast System
Publisher: American Meteorological Society
Abstract: The Climate Forecast System (CFS), the fully coupled ocean?land?atmosphere dynamical seasonal prediction system, which became operational at NCEP in August 2004, is described and evaluated in this paper. The CFS provides ...
