Antarctic 20th Century Accumulation Changes Based on Regional Climate Model Simulations

Net surface mass balance (mm/year) “AAO⁺¹ minus AAO⁻” years (a) and the “AAO⁺² minus AAO⁻” years (b), based on HIRHAM simulations in colours. The corresponding differences in annually averaged mean sea level pressure (hPa) are shown as isolines. The areas of significant positive and negative changes above the 95% confidence level are indicated by colour. White spaces indicate regions with a confidence level below 95%.
