Research Interests

        Broadly speaking, my research explores the spatial and temporal patterns of atmospheric processes/patterns and the chipmultiple linkages of these processes/patterns to surface weather and climate variability. I utilize a synoptic climatological approach whereby samples of various types of weather events, such as heavy rainfall, thunderstorms, and heat waves, are examined statistically to determine the: 1) commonalities and differences in the synoptic or large scale patterns/processes and 2) atmospheric field features that most effectively distinguish event characteristics, such as intensity, spatial pattern and diurnal timing.

        In the last five years, I have been involved in an eclectic, but interrelated set of synoptic climatological projects. These projects include: 1) The determination of relationships between landfalling tropical cyclone attributes and precipitation processes/patterns 2) The assessment of spatial and temporal patterns of thunderstorm activity as inferred from cloud to ground (CG) lightning patterns; 3) The identification of regional variations in the synoptic patterns associated with warm season precipitation within the eastern U.S.; 4) The determination of relationships between orographic processes and precipitation patterns in the southern Appalachians; 5) The examination of relationships between warm season drought/heat waves and the synoptic to planetary scale circulation. The majority of this research has focused on weather events that commonly occur in the maritime tropical weather regime of the southeastern United States.

        An underlying theme in my research is the cross-scale connections between small and large scale atmospheric phenomena. In particular, I am interested in the nature of mesoscale convective patterns and their relationship with the larger scale synoptic environment, particularly as it relates to precipitation production. A better understanding of these relationships is needed in order to better predict extremely heavy rainfall. This is especially the case where tropical systems interact with mesoscale features such as coastal fronts or terrain features (e.g. the Blue Ridge escarpment in North Carolina). Additionally I am interested in the subtle, but significant cross-scale relationships that exist between the synoptic environment and mesoscale convective systems in which individual cells repeatedly develop and move over the same region.
