My Arctic weather feature of interest is the tropopause polar vortex (TPV) which can persist for weeks and can interact with the mid-latitude weather systems.

One particular area I am investigating is the impact TPV/jet stream interactions have on downstream forecasts.
To study this I have built a cycling modeling system that uses a global numerical weather prediction model (Model for Prediction Across Scales, MPAS) that is coupled with ensemble data assimilation (Data Assimilation Research Testbed, DART). I use the ensemble to look at the sensitivities between TPV charactieristics and downstream forecast error.

My research will be oriented towards numerical simulations of arctic cyclones, tropopause polar vorticies (TPVs), and arctic sea ice.

One particular area I am investigating is the impact TPV/jet stream interactions have on downstream forecasts I am interested in a wide variety of weather phenomena, with a focus on synoptic meteorology and numerical weather prediction.

My research is about comparing the climatology of TPVs in the Northern and Southern Hemispheres.

Research interest: I am a Ph.D. candidate working with Dr. David Parsons on several topics under the umbrellas of Rossby waves, upscale error growth in numerical weather prediction

and sub-seasonal forecasting. My dissertation focuses on the growth and propagation of model errors in Rossby wave packet structures and the large scale patterns that are intrinsically susceptible to medium-range forecast busts. Apart from research, I enjoy being active outdoors such as hiking and playing ultimate frisbee.

My current project involves the characterization of the three-dimensional structure of tropopause polar vortices (TPVs) using infrared and microwave retrieval data from polar-orbiting satellite observations.

This research aims to provide more observational knowledge of TPVs, and will complement past, ongoing, and future modeling and field studies of these features. I completed my undergraduate at the University of Massachusetts Amherst, where my capstone involved an REU field study that investigated the fjord water column next to the Kronebreen-Kongsvegen tidewater glacial system in Svalbard.
