Shian-Jiann Lin is a Taiwanese-American atmospheric scientist. 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]

Lin holds a master's degree in aeronautical engineering from the University of Oklahoma and a doctorate in geophysical fluid dynamics from Princeton University. 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,[6] which forms the basis for the community GOCART[7] and GEOS-Chem[8] transport models, and the Finite-Volume (FV) Dynamical Core,[9] which was used in earlier versions of the Goddard Earth Observing System and of the Geophysical Fluid Dynamics Laboratory Coupled Model,[10] both since upgraded to FV3,[11][12][13] and is still used in the second release of the Community Earth System Model.[14]

Lin joined GFDL in 2003. He has since led development of FV3, the extension of FV onto a cubed-sphere grid,[15] 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[16] performed in the US. Lin's continued model development has led to the prediction models HiRAM[17] and fvGFS.[18] The latter is a prototype for the Next-Generation Global Prediction System (NGGPS),[19] 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.[20][21] The first operational NGGPS model, an FV3-based Global Forecast System,[22] became operational on 12 June 2019.[23]

In 2018 Lin was named a fellow of the American Meteorological Society.[24]
