Hurricane formation in the Atlantic and eastern Pacific can be linked to a 9/56 Year Cycle: Hurricanes and thus Moon Sun tidal effects.

Formation of Depressions in the Indian Seas & Lunar Phase


Nature, Volume 210, Issue 5034, pp. 406-407 (1966).
Abstract: "It was recently shown that the occurrence of heavy rainfall (10 in. and above in 24 h) is related to lunar phase. It will be evident that such heavy falls are mostly associated with depressions, some of which intensify into cyclones and severe cyclones. A study was therefore undertaken to examine the dates of formation of depressions in the Indian Seas vis-à-vis the lunar phase. This communication was prompted by Bradley's article ``Tidal Components in Hurricane Development'' and is intended to provide some additional information to support his conclusions."

Observed Relationship Between Lunar Tidal Cycles& Formation of Hurricanes and Tropical Storms.
Monthly Weather Review. 1972; 100: 451-460
Abstract: "To examine the hypothesis of a worldwide relation between some lunar periods and tropical disturbances, we collected first-formation dates for 1,013 hurricanes and typhoons and 2,418 tropical storms in both hemispheres. Using the superposed epoch method, we found a lunar synodic cycle (29.53 days) in North Atlantic hurricane and northwest Pacific typhoon formation dates. About 20 percent more hurricanes and typhoons formed near new and full moon than near the quarters during a 78-yr period, showing a stronger peak at new moon than at full moon. Statistically, the existence of an effect dependent on the lunar synodic cycle is supported by a significance level of 7% on unsmoothed data from an analysis of variance for categorical data."

"During the same 78 yr. North Atlantic tropical storms that did not later become hurricanes tended to form near the lunar quarters. Several other categories of tropical storms were not clearly related to the synodic month. Severe tropical storms in two portions of the Indian Ocean over 75 yr formed more often several days after syzygy and quadrature, but this and other severe tropical storm results lack definition, probably due to poor data."

"Theoretical calculations of the lunar-solar gravitational tide showed that the anomalistic lunar cycle affects only the amplitude and not the timing of extrema. No marked anomalistic or latitude components in hurricane formation were found."

Influence of Lunar Phase on Daily Global Temperatures

Science 10 March 1995: Vol. 267. no. 5203, pp. 1481 - 1483
Abstract: "A newly available data set of daily satellite-derived, lower-tropospheric global temperature anomalies povides an opportunity to assess the influence of lunar phase on planetary temperature. These results reveal a statistically significant 0.02K modulation between new Moon and full  Moon, with the warmest daily global temperatures over a synodic month coincident with the occurrence of the full Moon. Spectral analysis of the daily temperature record confirms the presence of a periodicity that matches the lunar synodic (29.53 day) cycle. The precision of the satellite-based daily temperature record allows verification that the Moon exerts a discernible influence on the short term global temperature record." 

Temporal fluctuations of daily rainburst and the cycle of the lunar year
Hassan ALI GHAYOOR, Geography Department, Isfahan University, Isfahan, Iran
International Journal of Climatology. Vol 6, Issue 1. pp 83-95.
Abstract: "The purpose of this research is to investigate climatic fluctuations connected with the cycles of the lunar year. The rainfall data belonging to the Balcombe station, Sussex, England, are used. From these data, variations in the frequency per year of daily rainfalls over 25 mm, which in this research are called daily rainbursts, are investigated, and the results show that there is a quasi-regular fluctuation, connected with the cycles of the moon, in the number of daily rainbursts."

Fluctuations in North Atlantic Hurricane Frequency
Department of Meteorology, The Florida State University, Tallahassee, Florida
Journal of Climate. p 427-437. Vol 12. Feb 1999.
Abstract: “The annual record of hurricane activity in the North Atlantic basin for the period 1886–1996 is examined from the perspective of time series analysis. Singular spectrum analysis combined with the maximum entropy method is used on the time series of annual hurricane occurrences over the entire basin to extract the dominant modes of oscillation. The annual frequency of hurricanes is modulated on the biennial, semidecadal, and near-decadal timescales. The biennial and semidecadal oscillations correspond to two well-known physical forcings in the local and global climate. These include a shift in tropical stratospheric winds between an east and west phase [quasi-biennial oscillation (QBO)] and a shift in equatorial Pacific Ocean temperatures between a warm and cold phase [El Nin˜o–Southern Oscillation (ENSO)]. These climate signals have previously been implicated  in modulating interannual hurricane activity in the North Atlantic and elsewhere. The near-decadal oscillation  is a new finding. Separate analyses on tropical-only (TO) and baroclinically enhanced (BE) hurricane frequencies  show that the two components are largely complementary with respect to their frequency spectra. The spectrum  of TO hurricanes is dominated by timescales associated with ENSO and the QBO, while the near-decadal timescale  dominates the spectrum of BE hurricanes. Speculations as to the cause of the near-decadal oscillation of BE  hurricanes center on changes in Atlantic SSTs possibly through changes in evaporation rates. Specifically, cross-  correlation analysis points to solar activity as a possible explanation. ”

: "The time distribution of injuries is not random. To assess the potential impact of weather and the phase of the moon on accidents, adjustment for known periodic and nonperiodic factors may be important. We compared the incidence of injuries with quantitative and qualitative weather variables as well as the lunar cycle, after correction for calendar and holiday-related factors. METHODS: We extracted the daily number of trauma patients treated at the emergency department over 36 years (1970-2005) from the trauma database of our regional hospital. For each patient, age, sex, cause of injury, and severity of injury were recorded. This was combined with daily meteorological data including temperature, precipitation, sunshine, humidity, air pressure, and wind as well as the lunar phase. We also related the rate of change of these parameters with the incidence of injuries. A qualitative weather variable derived from temperature, sunshine duration, and precipitation was defined as bad, normal, or good. Periodicities were adjusted for with Poisson regression spline fitting analysis. RESULTS: Several weather variables were related with the number of injuries. For most of these, better weather conditions were associated with an increase in trauma incidence. Good weather, which was present on 16.5% of the days, resulted in 10.1% (9.3-11.4 95% CI) more traumas compared with normal weather. Full moon was associated with a 2.1% (1.1-3.0 95% CI) lower trauma incidence than new moon. CONCLUSIONS: Better weather conditions contribute to an increased incidence of trauma. Full moon is associated with a slightly lower trauma incidence."
