Lunar Synodical Period and Widespread Precipitation
Science, 1962Precipitation activity over broad areas appears to be closely associated with the monthly lunisolar cycle. Indexes of precipitation in the continental United States over a continuous 50-year period, and 91-year daily histories of individual stations, reveal that heavy rains occur most frequently in the first and third weeks of the synodical month.

The oscillation of the synodic period of the Moon: A ‘‘beating’’ phenomenon
American Journal of Physics, 1989The synodic period of the Moon (the period of the phases or the time from, say, full moon to full moon) exhibits oscillations about its mean value of 29.530 59 days which immediately suggest a ‘‘beating’’ between at least two frequencies. A Fourier analysis can provide some insight into the causes of the oscillation without the complexity of rigorous ...

The Lunar Synodical Period and Precipitation in the United States
Journal of the Atmospheric Sciences, 1964Abstract A cycle of 14.765 days, one-half of the lunar synodic month, can be demonstrated in the precipitation data for the United States for the period 1871–1961. Numerous rigorous statistical tests show that association is real and an estimate is obtained of the magnitude of the lunar effect.

Comparison of sunspot periods with planetary synodic period resonances
Nature, 1975FOR decades, the closeness of the 11.1-yr cycle of solar activity and the 11.86-yr period of Jupiter has been noted, along with some speculation that the planets may have a causal effect on triggering solar activity. Two studies1,2 have presented a planetary function which stays in phase for hundreds of years, and both of them considered the influence ...

Notable Two-Synodic-Period Earth-Mars Cycler
Journal of Spacecraft and Rockets, 2006Earth-Mars cycler trajectories (cyclers) could play an important role in a future human transportation system to Mars. A particular cycler that repeats every two synodic periods and has one intermediate Earth encounter is very promising. In a circular-coplanar model it requires no propulsive maneuvers, has 153-day transfer times between Earth and Mars,

The Solar and Cosmic-Ray Synodic Periodicity (1969–1998)
Space Science Reviews, 2001The synodic recurrence of the Mt. Wilson plage index (MPSI) and the Calgary cosmic ray (CR) intensity is investigated, using the wavelet power spectra in the range of 18–38 days, during the last three solar cycles. The unique temporal coincidence between the quasiiasynodic MPSI and the CR periods is detected in 1978–1982 (the 21st solar cycle).

Synodic periods of asteroids 333, 402, 481, and 800
Planetary and Space Science, 2000Abstract The asteroids 333 Badenia, 402 Chloe, 481 Emita and 800 Kressmannia have been observed using photoelectric photometry during their 1997 apparations. The obtained synodic periods are: 333 Badenia — 9.96 h; 402 Chloe — 7.111 h; 481 Emita — 14.35 h and 800 Kressmannia — 4.457 h. There are no published periods so far for the first three.

The synodic rotational period of asteroid 4332 Milton
Icarus, 2016Abstract The results of our new photometric observations of the main-belt asteroid 4332 Milton are presented. These observations were obtained on two successive nights in August 2012 at Canakkale University Observatory. The bimodal light curve amplitude and period were determined to be 0.16 ± 0.01 mag and 3.295 ± 0.005 h, respectively.

On the relation between the synodic and sidereal rotation period of the Sun
Solar Physics, 1996It is pointed out that by taking Kepler's second law into account, the ‘sidereal correction’, i.e., the correction to be added to the observed synodic rotation rate of the Sun in order to get the sidereal rate, can be calculated more directly than described in a recent paper by Rosa et al. (1995).

Canonical features of the Synodal and Soviet periods: the problems of episcopal powers
Праксис, 2023Статья посвящена проблематике церковно-государственных отношений, каноническая власть епархиальных архиереев была ограничена посредством вмешательства государственного аппарата в епархиальное управление. Особенность церковно-государственных правоотношений заключается в ограничительном характере государственно-правового и церковноправового ...
