CliC Scientific Steering Group

SSG11GroupPhotoA group of selected scientists - the CliC Scientific Steering Group (SSG) - has the overall responsibility for planning and guiding the CliC project. Its members are appointed by the Joint Scientific Committee (JSC) of the World Climate Research Programme, based on recommendations by the CliC SSG. The Chair (or Co-chairs) is responsible for recommending changes in SSG membership to the JSC. Initial membership is for three years and, as a rule, two extensions of two years each may be recommended. The SSG usually meets once a year.

 

James Renwick (Co-Chair, 1/2017-12/2019, WCRP Joint Scientific Committee Liaison 1/2013-12/2016)

James RenwickI am a professor of physical geography at Victoria University of Wellington, New Zealand. My career has included a decade in research at the NZ Met. Service, and 20 years of climate research at NIWA. I am fascinated by the general circulation of the atmosphere – how the atmosphere transports energy and momentum and what it does to achieve this. In particular I am interested in how heating in the tropics is communicated to higher latitudes by the excitation of large-scale waves and how this affects the storm tracks, jet streams, and the location and frequency of long-lived ‘blocking’ anticyclones. In recent years I have developed an interest in Antarctic climate, especially the growth and decay of Antarctic sea ice. How does the atmospheric circulation (the wind) affect sea ice extent and how this can be tied back to tropical influences? Beyond these topics, I have a general background in atmospheric physics, plus mathematics and statistics and have broad interests most aspects of climate, from the distant past to the near future. This includes paleoclimate reconstruction, synoptic climatology, climate modelling, climate change, and the use of statistical and matrix techniques to analyse large data sets. I served as a lead author for the IPCC 4th and 5th Assessment Reports, in Working Group I (physical science) and am chair of the Royal Society of New Zealand Climate Expert Panel.

His first visit to a glacier was in Patagonia in 1981.Since then, he has worked in many cold regions. He visited Svalbard by opening Japanese Arctic research station, and also Dome Fuji Antarctica in order to start up a new Antarctic inland station, drilling site, and AWS monitoring. He has joined Japanese, Australian and Swedish Antarctic Expeditions. In the Arctic, he has worked often in Alaska as the collaborator of IARC/UAF and Japanese project on linkage of land-sea ice processes. Since 2011, he has been working as the leading member of the Japanese Arctic research project, and also on international cryospheric and Arctic meetings.

Stephen Hudson (1/2016-12/2018)

StephenHudsonStephen Hudson is a research scientist at the Norwegian Polar Institute (NPI). His work focuses on processes in the polar atmosphere that impact the energy budget of ice and snow surfaces. Since beginning at NPI in 2008, Hudson has worked in the Arctic, primarily on sea ice in the Arctic Ocean, but now also on land and glaciers in Svalbard. His main interests are processes affecting the radiation budget of the surface, including those related to clouds and to surface properties, and processes driving turbulent heat fluxes in the polar atmospheric boundary layer. Before coming to NPI in 2008, Hudson completed his MS and PhD at the University of Washington, where he focused on the atmospheric boundary layer and solar radiation on the Antarctic Plateau. He works extensively on collecting and using field data with a variety of methods, and also uses radiative transfer and other process models to better understand the observations and processes.

She also studied Atmospheric Sciences as an exchange student at the University of Washington in Seattle, USA, from 2001-2002.

Alexandra’s research has focused on questions related to Arctic sea ice decline, the impact of Arctic sea ice and freshwater changes on the meridional overturning circulation, the dynamics of Arctic freshwater, and the climate of the last glacial period. In her research, Alexandra uses climate models in combination with observational datasets to study the dynamics of the Arctic climate system. Alexandra also enjoys sharing her knowledge of climate science with the public and has worked with the Education and Outreach Program at NCAR to help educate teachers and the public about climate research. As steering committee member of CliC, Alexandra hopes to help improve the usefulness and quality of multi-model comparisons of Arctic climate simulations and of model-data comparisons in the Arctic.
