Lunar and Solar Barometric Tides in Australia

چکیده
The lunar semidiurnal barometric tide Lz and the solar 2 4 , 12-, and &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 a t most Australian stations. But the annual amplitude minimum occurs only a t half the Australian stations during this season, contrary to the behavior of LZ over most of the globe.

Lunar Tides and the Long-Term Variation of the Peak Latitude Anomaly of the Summer Sub-Tropical High Pressure Ridge over Eastern Australia
This study looks for evidence of a correlation between long-term changes in the lunar tidal forces and the interannual to decadal variability of the peak latitude anomaly of the summer (DJF) subtropical high pressure ridge over Eastern Australia (LSA) between 1860 and 2010. A simple "resonance" model is proposed that assumes that if lunar tides play a role in influencing LSA, it is most likely ...
متن کاملLeast Squares Techniques for Extracting Water Level Fluctuations in the Persian Gulf and Oman Sea
Extracting the main cyclic fluctuations from sea level changes of the Persian Gulf and Oman Sea is vital for understanding the behavior of tides and isolating non-tidal impacts such as those related to climate and changes in the ocean-sea circulations. This study compares two spectral analysis methods including: Least Squares Spectral Analysis (LSSA) and Least Squares Harmonic Estimation (LSHE)...
متن کاملRemoval of barometric pressure effects and earth tides from observed water levels.
The effects of barometric pressure and earth tide changes are often observed in ground water level measurements. These disturbances can make aquifer test interpretation difficult by masking the small changes induced by aquifer testing at late times and great distances. A computer utility is now available that automatically removes the effects of barometric pressure and earth tides from water le...
متن کاملSemilunar Reproductive Cycles in Fundulus Heteroclitus (pisces: Cyprinodontidae) in an Area without Lunar Tidal Cycles
Although lunar spawning rhythms are relatively common in species of shallow-water fish, semilunar reproductive cycles have been reported in a small but growing number of species (Korringa 1947; Johannes 1978). Species with the best documented semilunar gonad and spawning cycles include the California grunion. LeurestMs tenuis, (Clark 1925); Atlantic silversides, Menidia menidia, (Middaugh 1981)...
متن کاملLunar Geophysics, Geodesy, and Dynamics
Experience with the dynamics and data analyses for Earth and Moon reveals both similarities and differences. Analysis of Lunar Laser Ranging (LLR) data provides information on the lunar orbit, rotation, solid-body tides, and retroreflector locations. Lunar rotational variations have strong sensitivity to moments of inertia and gravity field while weaker variations, including tidal variations, g...
