'Cloud effects on surface energy and mass balance in the ablation area of Brewster Glacier, New Zealand', by Jono Conway and Nicolas Cullen was published in The Cryosphere. http://www.the-cryosphere.net/10/313/2016/tc-10-313-2016.html

The paper shows that clouds force fundamental changes in the surface energy and mass balance of Brewster Glacier, New Zealand. Cloudy periods exhibit greater melt due to increased incoming long-wave radiation and higher atmospheric vapour pressure rather than through minimal changes in mean air temperature and wind speed. Surface mass-balance sensitivity to air temperature is enhanced in overcast compared to clear-sky periods due to more frequent melt and a strong feedback between precipitation phase and albedo.

The research is part of an ongoing program at the University of Otago to monitor the mass balance of the Brewster Glacier as a tool to understanding climate variability in the South Pacific, and is supported by Victoria University Wellington and NIWA.
