Shian-Jiann Lin (born 1958) is a Taiwanese-American atmospheric scientist and meteorologist. He is currently the head of the Weather and Climate Dynamics Division at the Geophysical Fluid Dynamics Laboratory, the lead developer of the GFDL Finite-Volume Cubed-Sphere Dynamical Core (FV3) [1] [2] [3] and a lead developer or key contributor to several weather and climate models developed using FV3. [4] [5]

Education and career

Lin earned a Bachelor of Science (B.S.) from National Taiwan University. He also holds a master's degree in aeronautical engineering from the University of Oklahoma and a doctorate in geophysical fluid dynamics from Princeton University. [6] After a postdoctoral position at the Center for Analysis and Prediction of Storms at the University of Oklahoma he became a scientist at the Laboratory for Atmospheres at NASA's Goddard Space Flight Center, where he developed the Lin and Rood advection scheme, [7] which forms the basis for the community GOCART [8] and GEOS-Chem [9] transport models, and the Finite-Volume (FV) Dynamical Core, [10] which was used in earlier versions of the Goddard Earth Observing System and of the Geophysical Fluid Dynamics Laboratory Coupled Model, [11] both since upgraded to FV3, [12] [13] [14] and is still used in the second release of the Community Earth System Model. [15]

Lin joined GFDL in 2003. He has since led development of FV3, the extension of FV onto a cubed-sphere grid, [16] and a relaxation of the hydrostatic assumption to allow explicit simulation of vertical accelerations. A collaboration with Goddard led to the first global cloud-resolving simulations [17] performed in the US. Lin's continued model development has led to the prediction models HiRAM [18] and fvGFS. [19] The latter is a prototype for the Next-Generation Global Prediction System (NGGPS), [20] for which FV3 was selected after a two-year evaluation period. It was found that FV3 produced more accurate forecasts with better numerical stability compared to competing dynamical cores without sacrificing realism, efficiency, or effective resolution. [21] [22] The first operational NGGPS model, an FV3-based Global Forecast System, [23] became operational on 12 June 2019. [24]

In 2018 Lin was named a fellow of the American Meteorological Society. [25]
