Lunar and solar barometric tides at Nandi,Fiji

Lunar and solar atmospheric tidal oscillations have been determined with satisfactory accuracy from 17 years 11 months of mean sea-level barometric pressure observations taken at Nandi, Fiji. In many respects, the results are consistent with previous tidal determinations in the south-west Pacific region, although these are few and widely scattered. However, the mean annual amplitude of the lunar tide at Nandi, as determined in this study, 88 b, is much greater than might have been expected from currently available global amplitude maps. Nevertheless, the probable correctness of this result has been confirmed by the analysis of nearly 6 years of similar data from Nausori (130 km E.S.E. of Nandi), which yielded a mean annual lunar amplitude of 88 b, compared with a Nandi amplitude of 83 b for a closely corresponding period.
