Long Term Temperature Trends at Scott Base, Antarctica

Abstract

Temperature data from Scott Base, Antarctica, for the years 1957-1999 were analysed for long-term trends using linear regression. The annual mean temperature was found to be increasing at 0.0290C yr-l , and monthly and seasonally averaged temperatures mostly showed increasing trends. The diurnal temperature range was found to be decreasing due to increases in daily minima.
