Project Description

Sixteen internship positions are available for undergraduate students to come and stay at the University of North Dakota. Learn about climate, the fundamentals of climate change, and complete your own research projects using NASA observational and model data! Accepted students will receive a stipend of $1100, free housing on the campus of UND, and free meals for the duration of the 8-week program.

Specific research projects will study:
1) Observed surface temperature trends
2) Projected future surface temperature trends
3) Snow and ice coverage change
4) Impacts of land use change

Interns will also receive training in using media technology, culminating in production of a webcast about investigating aspects of climate change using NASA data. These webcasts will then be presented to the community, and be posted on the Internet along with lesson plans to be used by regional middle and high school students.

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)

Climatology of outflow heights

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).
