Research

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

1. Meteorological Research on Mt. Everest: Recent research activities include installation of a network of meteorological stations – including the two highest in the world – in the Khumbu Himal (Everest) region of Nepal as part of the National Geographic and Rolex Perpetual Planet Everest Expedition in April/May 2019. The network will greatly improve climber safety on the main climbing routes on the south side of Mt. Everest through real-time meteorological monitoring and bias correction of numerical model output. The highest stations in particular have enabled the first in-situ characterization of the climate at the highest points on Earth and will improve paleoclimatic reconstructions from nearby ice cores. Recent publications include:

2. 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 was supported by two grants from the National Science Foundation and currently by National Geographic and Rolex. 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. Along with Dr. Gino Casassa and other Chilean partners, Dr. Perry installed the highest weather stations in the Americas at 6,505 m on Tupungato Volcano in the Chilean Andes in 2021. Selected recent publications are available below:

3. Snowfall Patterns and Processes in the Southern Appalachian MountainsResearch 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. 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:
