Research Interests

Jen Kay is an Associate Professor in the Department of Atmospheric and Oceanic Sciences and a Fellow of CIRES at the University of Colorado at Boulder. She remains a visiting scientist at the National Center for Atmospheric Research, where she worked prior to joining CU Boulder. Dr. Kay researches polar climate change, feedbacks, and variability, with a specific focus on connecting global coupled climate modeling with observed cloud, precipitation, and sea ice processes. She works at the nexus of observations and modeling to understand the processes controlling climate change and variability.

Current Research

Process-based understanding of climate physics and dynamics

Three current projects exemplify my strategic combination of models and observations to improve understanding of the processes controlling climate change and variability. First, ATOC/CIRES graduate student Matt Gentry and I are assessing the influence of clouds on Southern Ocean sea ice and biology with funding from my NSF CAREER award. Second, I am a co-I on a $35 million NASA Earth Ventures mission callled Polar Radiant Energy in the Far Infrared Experiment (PREFIRE). In this 2018-2023 project, we will launch two small CubeSat satellites to measure previously undetected Arctic radiation at far-infrared wavelengths. My role in PREFIRE is analyzing the new observations and using them to improve modeling of Arctic climate. Finally, with funding from NASA, I am assessing the observability of and the mechanisms underlying hydrologic cycle changes with global warming. Comparisons based on recently developed radar simulator diagnostics (Kay et al. 2018) show a state-of-the-art climate model has excessive rain and snow frequency, but insufficient heavy rain frequency. We are currently exploring the detectability and reliability of projected 21st century precipitation changes, including the future of snow (see figure below, adapted from Kay et al. 2018 Figure 11).

Figure shows the future of snow, i.e., 21st century change in 94 GHz spaceborne radar snow occurrence frequency in a global coupled climate model (Community Earth System Model). Figure from Kay et al. 2018 JGR Atmospheres.
