Climatic change on King George Island in the years 1948–2011
Abstract The climatic change on King George Island (KGI) in the South Shetland Islands, Antarctica, in the years of 1948-2011 are presented. In the reference period, a statistically significant increase in the air temperature (0.19ºC/10 years, 1.2ºC in the analysed period) occurred along with a decr...

Abstract The climatic change on King George Island (KGI) in the South Shetland Islands, Antarctica, in the years of 1948-2011 are presented. In the reference period, a statistically significant increase in the air temperature (0.19ºC/10 years, 1.2ºC in the analysed period) occurred along with a decrease in atmospheric pressure (−0.36 hPa/10 years, 2.3 hPa). In winter time, the warming up is more than twice as large as in summer. This leads to decrease in the amplitude of the annual cycle of air temperature. On KGI, there is also a warming trend of daily maximum and daily minimum air temperature. The evidently faster increase in daily minimum results in a decrease of the diurnal temperature range. The largest changes of air pressure took place in the summertime (−0.58 hPa/10 years) and winter (−0.34 hPa/10 years). The Semiannual Oscillation pattern of air pressure was disturbed. Climate changes on KGI are correlated with changing surface temperatures of the ocean and the concentra− tion of sea ice. The precipitation on KGI is characterised by substantial variability year to year. In the analysed period, no statistically significant trend in atmospheric precipitation can be observed. The climate change on KGI results in substantial and rapid changes in the environment, which poses a great threat to the local ecosystem. |
