Some Often (by the standards of our field) Requested Publications

High-End Climate Science: Development of Modeling and Related Computing Capabilities

This report was written for the Office of Science and Technology Policy in 2000. It's an analysis and strategy for organizing climate modeling in the U.S. Some consider it a "computing report," but that's not all the authors intended. The report discusses the fragmentation of U.S. climate modeling resources, the need for an integrating software infrastructure, and the relationship of climate modeling to high performance computing.

1987 Reviews of Geophysics Advection Review

Because people still ask for it. This is an introduction to modeling advection of atmospheric tracers. It contributed prominently to my career and the development of a dynamical core with S.J. Lin. It gives some the impression that I am an "expert" on numerical techniques. I am not.

Recent Publications

Evaluation of a CCSM3 Simulation with a Finite Volume Dynamical Core for the Atmosphere at 1° Latitude by 1.25° Longitude Resolution Bala et al., J. Climate, 2008.

Simulated Climate near Steep Topography: Sensitivity to Numerical Methods for Atmospheric Transport Bala et al., Geophys. Res. Lett., 2008

Don't "Sell Short" the Earth:Carbon tax will ease transition to sensible climate policy Rood and Thoumi, feature article, 2008.

Lin-Rood Dynamical Core

This dynamical core, often called Lin-Rood or Finite Volume or, just, FV has been widely used. Someday it will just be called the Lin Core. It consists of a horizontal advection scheme, a treatment of the pressure gradient term, and a Lagrangian vertical coordinate. Here they all are:

Multi-Dimensional Flux-Form Semi-Lagrangian Transport Schemes Lin and Rood, Mon. Wea. Rev., 1996. This is the advection scheme for tracers. This includes the "requirements" for a physically based scheme.

An explicit flux-form semi-Lagrangian shallow-water model on the sphere Lin and Rood, Q. J. Roy. Meteor. Soc., 1997. This paper takes the advection scheme to be a dynamical core.

A finite-volume integration scheme for computing pressure gradient force in general vertical coordinates Lin, Q. J. Roy. Meteor. Soc., 1997. This is the finite-volume treatment of pressure gradient, which has a big impact near steep topography.

A ‘‘Vertically Lagrangian’’ Finite-Volume Dynamical Core for Global Models Lin, Mon. Wea. Rev., 2004. This is THE reference for the dynamical core.

Blogs and Resume (Again)

I put a lot of work into the blogs and lots of interesting things have come from them. Updated, at least, weekly. Physical climate, impacts, an occasional opinion piece, sometimes a bit of news.
