Abstract:

The scientists of atmoshperic tide (e.g., Chapman, 1924) thought that the solar diurnal barometric oscillation is suppressed and the solar semidiurnal barometric oscillation is magnified. This viewpoint has continued for quite a few decades. However, the analgsis of the Antarctic data shows that the solar diurnal barometric oscillation is much stronger than the semidiurnal one on the ground surface in the Antarctica.This conclusion is agreed with that given by Gao et al. (1986) using the data of 205 stations in China. From the above, it seems to be that the solar diurnal barometric oscillation is not suppressed and the semidiurnal one is also not magnified on the ground surface in the Antarctica, thus it is different from Chapman's result. Meanwhile, it's got from the analysis that the solar semidurnal temperature oscillation is stronger than durnal one in some Antarctic winter months. It is different from that in non-polar region, which seems to be not directly produced by solar radiation. And, the solar semidurnal barometric oscillation isn't stronger than the durnal one when the semidurnal temperature oscillation is stronger than the durnal temperaure one, which probably expresses that the cause of barometric oscillation on the ground surface is complex with many effecting factors.
