Research Interests:

Analysis of mid-latitude, synoptic-scale weather systems; dynamics and kinematics of fronts and frontogenesis; cyclogenesis; structure and evolution of cyclones; energetics of the cyclone life cycle; meso- and synoptic-scale dynamics and precipitation production and distribution in mid-latitude and subtropical cyclones.

Recently the opinion has been voiced by some members of the research community that "the cyclone problem has been solved." Nothing could be farther from the truth!

Issues as seemingly clear- cut as the 3-D structure and evolution of mid- latitude cyclones are hotly debated topics. My research interests include the diagnosis of the structure of midwest winter cyclones and the effect that that structure has on both the production and distribution of precipitation within these cyclones. This work involves a combination of observational analysis (in which a multi-scale approach is used) as well as the use of high resolution meoscale numerical model simulations of selected storms. The "multi-scale" approach means that we consider processes that vary in scale from the planetary scale effects of the Rocky Mountain cordillera on the baroclinically unstable westerly flow, down to the micron-sized cloud microphysical processes responsible for the production of individual precipitation particles. This approach is compelled by the fact that the precipitation production and distribution in cyclones is the result of a scale interaction between all scales of motion in the atmosphere and that a consistent description of how the mid-latitutde cyclone really works cannot be given without considering all of these scale-dependent processes.

I have also become interested in the problem of cyclolysis, the last stage of the cyclone life cycle. Very little is really understood about this process despite the fact that cyclolysis represents such an important component of the complete life cycle. We have investigated this problem from the synoptic-climatological perspective as well as from the case study and local energetics perspective. Many outstanding issues remain in this broad topic.

B Recently our group has placed research emphasis on the distribution and nature of subtropical cyclones. Among the many questions that have arisen out of that work are 1) What processes are essential to the transformation of a subtropical cyclone with extratropical structures into a tropical cyclone?, 2) What processes lead to the development of active and inactive periods of subtropical cyclogenesis in the northern ocean basins?, and 3) What is the role of diabatic heating in the subtropical cyclone life cycle?

Our research group uses a variety of tools to conduct its research including fine-scale numerical models, local energetics diagnostics, quasi-geostrophic diagnostics, piecewise potential vorticity diagnostics, as well as a variety of statistical and compositing software packages developed specifically for the questions at hand. A student with an interest in observational as well as, or in combination with, dynamical/theoretical meteorology would be well served by the palette of research questions I am currently entertaining.
