Abstract

The lunar semidiurnal barometric tide L2 and the solar 24-, 12-, and 8-hr. oscillations of the surface pressure have been determined for 10 stations in Australia and on adjacent islands. At Rabaul and Moresby L2 is considerably smaller than elsewhere in these latitudes. The characteristic annual variation of the phase—late high tide during the D season—is found at most Australian stations. But the annual amplitude minimum occurs only at half the Australian stations during this season, contrary to the behavior of L2 over most of the globe.
