Further information

Abstract: The Eta numerical weather prediction model will be described. The main features of the model dynamical core are reviewed, emphasizing upgrades to the version downloadable at the NCEP "Workstation Eta" site. These upgrades include implementation of "sloping steps" topography, and replacement of the centered finite-difference vertical advection of dynamic variables by a finite-volume scheme. This makes the Eta model very nearly a finite volume model, due to its quasi-horizontal coordinate surfaces and use of the Arakawa flux-type schemes conserving a variety of physically important quantities.
