Research Interests

Tracer transport in deep convection

Comparison of detrainment heights computed from soundings with radar observations - Poster by Amanda Homann, presented at North Dakota EPSCoR conference, Sept. 2008

Radar reflectivity as a proxy for convective mass transport (see publication below)

collaborating with Courtney Schumacher at Texas A&M

Global climate change education

The University of North Dakota was funded by NASA Global Climate Change Education program to improve climate learning and communication for both undergraduates and middle school students in the Northern Plains. Click here for more information on GCCE and here for more on UND's involvement.

Discrete propagation of convection

Continuous propagation describes the generation of new cells at the edge of the gust front.  Discrete propagation refers to cell initiation that, while not generated at the outflow edge, is significantly influenced by nearby or previous convection (e.g. gravity waves propagating beyond gust front or fossilized cold pools).
