RESEARCH

Dr. Perry’s research interests include precipitation, snow and ice, tropical glacier-climate interactions, and climate change. Mountain regions serve as a focus, with specific interests in the tropical Andes and Appalachian Mountains. His current research is organized around three major topics:

1. Precipitation-Climate-Glacier Interactions in the Tropical Andes Mountains: Research priorities include investigating precipitation patterns and processes across the Andean region, investigating the atmospheric influences on oxygen stable isotopes and trace elements preserved in high-elevation snowfall, and decoding multi-centennial climate histories from tropical Andean ice cores. This work is currently supported by two grants from the National Science Foundation: Multiscale Investigations of Tropical Andean Precipitation (PI Perry) and Ultra-High-Resolution Investigation of High Andean Snow and Ice Chemistry To Improve Paleoclimatic Reconstruction and Enhance Climate Prediction (PIs Anton Seimon at Appalachian State University and Paul Mayewski at the Climate Change Institute, University of Maine). As part of these projects, Dr. Perry has installed comprehensive precipitation monitoring stations on the Quelccaya Icecap in Peru at 5,650 m and at the Chacaltaya Observatory at 5,160 m in Bolivia. Appalachian has active partnerships with the Universidad Mayor de San Andrés in Bolivia (UMSA), Universidad Nacional de San Antonio Abad de Cusco (UNSAAC) in Peru, and the Servicio Nacional de Meteorología e Hidrología (SENAMHI) of Peru.

2. Snowfall Patterns and Processes in the Southern Appalachian Mountains: Research activities include investigation of multiscale atmospheric processes influencing snowfall formation, from the hemispheric (e.g., Arctic Oscillation and El Niño-Southern Oscillation) to the cloud microphysical (e.g., snow particle type and degree of riming, moist layer temperature and thickness). Dr. Sandra Yuter (NCSU), Dr. Douglas Miller (UNCA), Stephen Keighton (NOAA-NWS), and the Northwest Flow Snowfall Discussion Group are important partners in this ongoing project. Event summaries from 2006 to 2009 are available on Dr. Yuter’s page. A comprehensive snow and precipitation monitoring station was installed at 1,875 m asl on Roan Mountain, NC, in 2012. Recent publications include the following:

3. Appalachian Atmospheric Interdisciplinary Research (AppalAIR): The AppalAIR mission is to improve understanding of atmospheric properties and processes and the associated impacts on terrestrial ecosystems and climates in the southern Appalachian Mountains. As such, Dr. Perry currently manages meteorological stations on the Appalachian campus and at Grandfather Mountain, Beech Mountain, Poga Mountain, and Bethel Elementary School. Former student Ginger Kelly completed a master’s thesis entitled Aerosol-Precipitation Interactions in the Southern Appalachian Mountains, with two publications from this work:
