Research Interests

My research focuses on the stable atmospheric boundary layer (ABL) where the Earth’s atmosphere interacts with its surface. The stable ABL occurs when the atmosphere is coldest near the surface. Improving our understanding of the stable ABL in high latitudes and its response to changing atmospheric dynamics and surface characteristics is important as the science community seeks to better forecast variability and changes in high-latitude climate.


Current Research

Currently I am using data from two polar sites, in Greenland and Antarctica. My colleagues and I have recently completed a paper using four summers of measurements of nitrogen oxide (NO: produced by photolysis of snow nitrate) at the South Pole.  These data reveal the combined effects of a bimodal distribution of winds at 300 hPa in late November into December (where winds aloft between 90oE and 180o lead to light surface winds and shallow boundary layers) and the delay in the breakup of the ozone hole in recent decades. With lower total ozone column density and higher sun elevation, the highest actinic flux responsible for the photolysis of snow nitrate now occurs under the shallow boundary layer conditions optimum for accumulation of NO to levels up to 1000 pptv.  Further results related to the ICECAPS field program (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit) have focused on the role of atmospheric rivers (ARs) in transporting warm, high-moisture air to Greenland. As one step in this analysis, we have documented the ability of three reanalyses (ERA-I, NCEP/DOE, and the Twentieth Century Reanalysis or 20CR) to identify these events over the period 2000-2012. We have largely focused on transport of moisture by ARs along the west coast of Greenland during the summer (June-August) which often occur as a result of cyclonic Rossby Wave breaking and which can accelerate the melting along the western boundaries of the ice sheet. We are planning to extend the analysis to 1871 using the 20CR.
