PNNL

Dr. Lubis is an atmospheric scientist with a broad interest in atmospheric dynamics and climate variability and change. The main focus of his work is to advance the fundamental understanding of large-scale atmospheric processes that impact extratropical and tropical weather and climate. Potential topics of interest include, but are not limited to, the dynamics of large-scale circulation (such as sudden stratospheric warmings, blockings, annular modes, stationary waves, planetary wave reflection, and wave breaking), tropical meteorology (including moisture modes, MJO, equatorial waves, and cold surges), and extreme weather.

Before joining PNNL in the summer of 2022, Dr. Lubis was a Postdoctoral Researcher working with Prof. Noboru Nakamura (University of Chicago, USA) and Prof. Pedram Hassanzadeh (Rice University, Houston, USA). Dr. Lubis received his Ph.D. in Atmospheric Sciences from GEOMAR - Helmholtz Centre for Ocean Research Kiel and the University of Kiel, Germany, under the supervision of Prof. Katja Matthes and Prof. Nili Harnik. Outside of work, he enjoys listening to and watching classical music concerts (a big fan of Bach, Sibelius, Paganini, Shostakovich, and Tchaikovsky), traveling, and exploring nature.
