Progress in Development of the Flow-Following Finite-Volume Icosahedral Model (FIM) Toward Improving NCEP Global Ensemble Forecasts and Toward a Chemistry-Coupled Global Model Research Capability

In this presentation, we will focus on improvements to the FIM since June 2009, including those in physics, vertical coordinate, and inline chemistry with treatment of volcanic ash. After a very brief review of the numerical characteristics of the FIM model [isentropic-sigma-hybrid vertical coordinate, finite-volume (FV) transport, icosahedral h...

Four-dimensional variational data assimilation for WRF: Formulation and preliminary results

The Weather Research and Forecasting (WRF) model–based variational data assimilation system (WRF-Var) has been extended from three- to four-dimensional variational data assimilation (WRF 4D-Var) to meet the increasing demand for improving initial model states in multiscale numerical simulations and forecasts. The initial goals of this developmen...

Parallelization and Performance of the NIM Weather Model on CPU, GPU, and MIC Processors

The design and performance of the Non-Hydrostatic Icosahedral Model (NIM) global weather prediction model is described. NIM is a dynamical core designed to run on central processing unit (CPU), graphics processing unit (GPU), and Many Integrated Core (MIC) processors. It demonstrates efficient parallel performance and scalability to tens of thou...

A Vertically Flow-Following Icosahedral Grid Model for Medium-Range and Seasonal Prediction. Part I: Model Description

A hydrostatic global weather prediction model based on an icosahedral horizontal grid and a hybrid terrain-following/isentropic vertical coordinate is described. The model is an extension to three spatial dimensions of a previously developed, icosahedral, shallow-water model featuring user-selectable horizontal resolution and employing indirect ...
