“…In particular, a considerable circumstantial evidence [ Boberg and Lundstedt , 2002; Thejll et al , 2003, Palamara and Bryant , 2004] is increasingly pointing to GIAA as one of the most influent precursors of the NAO variability. Such GIAA‐NAO perspective, coupled with the known dependence of GIAA on solar activity [see, e.g., Richardson et al , 2000; Charvátová and Střeštík , 2007], feeds the hypothesis that the solar‐type signals formerly observed in Venetian sea levels [ Tomasin , 2005; Zanchettin et al , 2006] are expressions of a robust, deeper large‐scale net of interactions between the Sun and the Earth's climates.…”

“…Notably, τ has a deterministic nature, since it essentially depends on the constellation of the four major planets [see, e.g., Wilson et al , 2008]. Although the nature of the mechanisms causing the coupling is not completely clear yet, several empirical evidences suggest that τ and HC are coupled [ Charvátová and Střeštík , 2007; Wilson et al , 2008; P1], and that the HC pattern closely traces that of τ within peculiar periods. In particular, Charvátová [2000] showed how the stable behavior of the solar inertial motion could contribute to periods of exceptional and stable behavior in sunspot activity.…”

“…More recently (P1), we showed that τ and HC covaried in remarkable synchrony during the weak sunspot cycles between the 13th and the 19th. Notably, during weak sunspot cycles, several solar‐terrestrial phenomena such as GIAA and volcanic activity apparently display an exceptional and stable behavior [ Sato et al , 1993; Charvátová and Střeštík , 2007]. Meanwhile a physically plausible model is developed to explain such apparent τ ‐HC coupling, the interesting potential spin‐offs in the field of long‐term forecasting of solar activity can already be discussed.…”

Teleconnections force interannual‐to‐decadal tidal variability in the Lagoon of Venice (northern Adriatic)

[1] In the present investigation, for the first time, fundamental characteristics of autumn and winter average sequences of sea level heights (SLH) that were recorded in the Lagoon of Venice (northern Adriatic, in the Mediterranean Sea) during the period 1872-2004 are investigated. Interannual-to-decadal variability of Venetian SLH is found to reflect the variability of the most prominent Euro-Atlantic teleconnections (EATs). In particular, the North Atlantic Oscillation (NAO), the East Atlantic/Western Russian, and the Scandinavian patterns are found to contribute to generate the $5-year, $8-year and $22-year peaks that dominate the spectra of seasonal Venetian SLH. Among the possible oceanic and atmospheric phenomena downscaling interannual-to-decadal large-scale atmospheric signals into the observed variability in the Venetian SLH, we explore inverse barometer effect, wind-driven setup, and the thermohaline circulation of both the Adriatic and the Mediterranean seas. All these phenomena are assessed to display some of the typical features of the shared interannual-to-decadal variability of both Venetian SLH and EATs. Our analysis shows also that the decadal variability of winter Venetian SLH is closely linked with variations in solar activity: in particular, the winter SLH multidecadal pattern is found to be correlated, with very high statistical confidence, to the Hale Cycles pattern ($22 years), which describes the series of sunspot cycles with alternating opposite polarity. The marked signature of Hale Cycles on the leading mode of multidecadal sea level pressure winter variability (which is practically indistinguishable from the inverse wintertime NAO) is also detailed to further support the hypothesis of a Sun-Venetian SLH association.

“…McCracken (2014) and Wilson et al (2008) found that solar activity is related to the movement of the planetary system. Charvátová (1990), Charvátová and Střeštík (2007), Scafetta et al (2016), and Yndestad and Solheim (2017) studied the relation between the movement of the Sun and solar activity. Jager and Versteegh (2005) also discussed the link between the movement of the planetary system and solar activity.…”

Abstract. The relationship between the periodic movement of the planetary system and its influence on solar activity is currently a serious topic in research. The kinematic index of the planet juncture index has been developed to find the track and variation of the Sun around the centroid of the solar system and the periodicity of solar activity. In the present study, the kinematic index of the planetary system's heliocentric longitude, developed based on the orbital elements of planets in the solar system, and it is used to investigate the periodic movement of the planetary system. The kinematic index of the planetary system's heliocentric longitude and that of the planet juncture index are simulated and analyzed. The numerical simulation of the two kinematic indexes shows orderly orbits and disorderly orbits of 49.9 and 129.6 years, respectively. Two orderly orbits or two disorderly orbits show a period change rule of 179.5 years. The contrast analysis between the periodic movement of the planetary system and the periodicity of solar activity shows that the two phenomena exhibit a period change rule of 179.5 years. Moreover, orderly orbits correspond to high periods of solar activity and disorderly orbits correspond to low periods of solar activity. Therefore, the relative movement of the planetary system affects solar activity to some extent. The relationship provides a basis for discussing the movement of the planetary system and solar activity.
