Antarctic winter tropospheric warming—the potential role of polar stratospheric clouds, a sensitivity study
Abstract Over the last 30 years, Antarctic mid‐tropospheric temperatures in winter have increased by 0.5 K per decade, the largest regional tropospheric warming observed. Over this period, amounts of polar stratospheric cloud(PSC) have also increased, as rising CO 2 concentrations cooled the stratos...
