James Wilczak

Team Lead, Boundary Layer Processes and Applications

Physical Sciences Division


Dr. Wilczak is a research Meteorologist working to better understand the nature of turbulence, its effect on the atmospheric boundary layer, and the role of the boundary layer on shaping both weather and climate.

Research Interests

Dr. Wilczak's research interests include the atmospheric boundary layer, its representation in climate and weather models, and measurement of the boundary layer using remote sensing instrumentation. How do we define the boundary layer, are our measurement systems capable of observing the boundary layer, and do our climate and weather forecast models have any skill at predicting boundary layer structure? He has applied his expertise to applied research programs in air quality and wind energy, both of which are strongly dependent on the state of the boundary layer.


Dr. Wilczak is the author/coauthor of more than 50 refereed publications, published in 15 different journals, with his papers receiving more than 100 citations per year. He has led in the application of remote sensing technologies for measuring the atmospheric boundary layer, improved techniques for the measurement of turbulent fluxes, and produced fundamental research on the nature of turbulence.
