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 on different timescales via tropospheric and stratospheric pathways.

Priyanka has worked on diverse research projects including tropical-extratropical interactions due to the MJO via tropospheric and stratospheric pathways, stratosphere-troposphere coupling, the North American monsoon, the Indian summer monsoon and its links to the ENSO and IOD, and studying the stratospheric ozone depletion.
