John Turner is a research scientist at the British Antarctic Survey in Cambridge, UK where he leads a project investigating the climate of the Antarctic. He has a B.Sc in Meteorology and Physics and a Ph.D in Antarctic Climate Variability. He was employed by the UK Meteorological Office from 1974 to 1986 where he was involved in the development of numerical weather prediction models and satellite meteorology. Since 1986 he has been at BAS, investigating high-latitude precipitation, polar lows, teleconnections between the Antarctic and lower latitudes and weather forecasting in the Antarctic. He was the President of the International Commission on Polar Meteorology from 1995 to 2003 and is presently a Vice-President of the International Association of Meteorology and Atmospheric Sciences. He chairs the Scientific Committee on Antarctic Research (SCAR) Advisory Group on Antarctic Climate Change and the Environment. He is co-author of King and Turner (1997)Antarctic Meteorology and Climatology, co-editor of Rasmussen and Turner (2003) Polar Lows: Mesoscale Weather Systems in the Polar Regions and co-author of Turner and Marshall (2011) Climate Change in the Polar Regions, all of which were published by Cambridge University Press. He has received a number of awards, including the International Journal of Climatology Prize of the Royal Meteorological Society and the SCAR Medal for Excellence in Antarctic Research.
