Research Interests

My research has provided fundamental contributions to the understanding of atmospheric boundary layer (ABL) processes in complex landscapes and how this surface complexity affects the variability of the ABL in space and time. My contributions have come from extensive studies of the ABL using a combination of observational, theoretical, and numerical modeling tools. In many cases, I start with the design and execution of hypothesis-driven field experiments that are followed by theoretical and numerical modeling studies. In some other cases, theoretical and numerical modeling studies precede, rather than follow, field experiments. My current research emphasizes the atmosphere over mountains, but I am also addressing the atmosphere over other landscapes such as flat and inhomogeneous, urban, and coastal areas. I focus on ABL processes at spatial scales of a few kilometers (local scale) to tens of kilometers (mesoscale) and temporal scales of hours to days. These local and mesoscale processes are highly relevant for applied, interdisciplinary studies that form an important part of my research agenda.
