Dr. Jui-Lin (Frank) Li, is a Research Scientist in Earth Science Division at JPL, and a Project Scientist in the JIFRESSE at UCLA. His principal research interests lie in regional meso-scale model and global atmosphere-ocean-land-cryosphere modeling, as well as in climate dynamics and climate projection, with emphasis on the hydrometeors-radiation interactions. Recent several publications from Li et al. (see publication lists bellowed) have reported that the radiative effect of precipitating ice (snow) is excluded in most of the conventional global climate models (GCMs) including CMIP5/CMIP6. Dr. Li and his team identified biases in cloud ice, total cloud fraction, and surface radiative forcing in CMIP5 and CMIP6 on air-sea interactions, land, sea ice simulated in CMIP5 and CMIP6 GCMs.
