Brief Bio

Priyanka Yadav is an Assistant Research Scientist with the University of Maryland Earth System Science Interdisciplinary Center and the Global Modeling and Assimilation Office at NASA Goddard Space Flight Center.

Her research focuses on improving predictability of the atmospheric circulation on subseasonal to seasonal (S2S) timescales using observational data, climate models, and advanced statistical techniques. She is interested in understanding the dynamics of the large-scale circulation, and the influence of tropical variability (e.g. Madden-Julian Oscillation (MJO), Indian Ocean Dipole (IOD), and ENSO) on global weather and climate across different timescales via tropospheric and stratospheric pathways.

Priyanka's scientific contributions span across a wide range of research projects, including teleconnections arising from fast and slow MJO episodes via tropospheric and stratospheric pathways, stratosphere-troposphere coupling in S2S models, the North American monsoon, the South Asian monsoon and its links to the ENSO and IOD, air pollutant dispersion modeling, and studying the stratospheric ozone depletion using TOMS data.

Current Projects

Seamless Prediction and Predictability across weather-subseasonal-seasonal timescales.
