Abstract

The surface pressure of an Antarctic station displays two minima, one in spring, the other in autumn. It is believed that these minima are caused by radiative forcing, as the gradient of the extra-terrestrial radiation is largest during the two equinoxes. The best correlation (r = 0.85) was obtained when the pressure lagged the radiation gradient by ten days.
