Levi Silvers is a Research Scientist in the Department of Atmospheric Science at Colorado State University. He received his Ph.D. in Atmospheric Science from CSU in 2011. Levi’s research is focused on the mechanisms by which clouds and atmospheric moisture influence the flow of energy through the Earth’s system. There are many fascinating phenomena in the Earth system that are influenced by the interacations between clouds and atmospheric moisture. These include tropical cyclones, overturning tropical circulations such as the Hadley and Walker circulations, and the response of cloud radiative effects to particular patterns of sea surface temperature. Levi’s research has made use of a variety of modeling tools that include global Earth-like climate models, idealized mock-Walker simulations, and simulations of radiative-convective equilibrium. After finishing his Ph.D. Levi moved to Germany for a post-doctoral position at the Max-Planck Institute for Meteorology. Levi also worked at the Geophysical Fluid Dynamics Laboratory as the lead scientist for GFDL's participation in the Cloud Feedback Model Intercomparison Project during CMIP6 and as a Research Scientist at Stony Brook University in the School of Marine and Atmospheric Science. Levi derives great satisfaction from spending time with his family and by being outside, whether atop mountains or along the sea.
