“…In Brazil, dendrochronological/dendroclimatic studies are still incipient (Fritts, 1976;Schöngart et al, 2002Schöngart et al, , 2004Rigozo et al, 2007aRigozo et al, , b, 2008Lisi et al, 2008;Oliveira et al, 2009;Prestes et al, 2011Prestes et al, , 2014Andreacci et al, 2013;Pagotto et al, 2015;Lorensi and Prestes, 2016;Lorensi, 2016;Perone et al, 2016), considering the great biodiversity and continental dimension of Brazil when compared to South American countries such as Chile and Argentina. However, these kinds of studies have become more numerous in the recent years (Rigozo et al, 2007a(Rigozo et al, , b, 2008Lisi et al, 2008;Oliveira et al, 2009;Prestes et al, 2011Prestes et al, , 2014Andreacci et al, 2013;Pagotto et al, 2015;Lorensi and Prestes, 2016;Lorensi, 2016;Perone et al, 2016).…”

Abstract. In this work, the Sun-Earth-climate relationship is studied using tree growth rings of Araucaria angustifolia (Bertol.) O. Kuntze collected in the city of Passo Fundo, located in the state of Rio Grande do Sul (RS), Brazil. These samples were previously studied by Rigozo et al. (2008); however, their main interest was to search for the solar periodicities in the tree-ring width mean time series without interpreting the rest of the periodicities found. The question arises as to what are the drivers related to those periodicities. For this reason, the classical method of spectral analysis by iterative regression and wavelet methods are applied to find periodicities and trends present in each tree-ring growth, in Southern Oscillation Index (SOI), and in annual mean temperature anomaly between the 24 and 44 • S. In order to address the aforementioned question, this paper discusses the correlation between the growth rate of the tree rings with temperature and SOI. In each tree-ring growth series, periods between 2 and 7 years were found, possibly related to the El Niño/La Niña phenomena, and a ∼ 23-year period was found, which may be related to temperature variation. These novel results might represent the tree-ring growth response to local climate conditions during its lifetime, and to nonlinear coupling between the Sun and the local climate variability responsible to the regional climate variations.

“…The 33-year cycle (Bruckener cycle) is also caused by the solar origin, but it is a very rare cycle (Kasatkina et al, 2007). The 2-7-year ENSO cyclic pattern and its possible coupling process are the major driving forces for the temperature variability (Gray et al, 1992;Wiles et al, 1998;Mokhov et al, 2000;Rigozo et al, 2007, Kothawale et al, 2010. El-Borie and Al- Thoyaib (2006) and El-Borie et al (2007 have indicated in their studies that the global temperature should lag the geomagnetic activity with a maximum correlation when the temperature lags by 6 years.…”

Abstract. To study the imprints of the solar-ENSOgeomagnetic activity on the Indian subcontinent, we have applied singular spectral analysis (SSA) and wavelet analysis to the tree-ring temperature variability record from the Western Himalayas. Other data used in the present study are the solar sunspot number (SSN), geomagnetic indices (aa index), and the Southern Oscillation Index (SOI) for the common time period of 1876-2000. Both SSA and wavelet spectral analyses reveal the presence of 5-7-year short-term ENSO variations and the 11-year solar cycle, indicating the possible combined influences of solar-geomagnetic activities and ENSO on the Indian temperature. Another prominent signal corresponding to 33-year periodicity in the tree-ring record suggests the Sun-temperature variability link probably induced by changes in the basic state of the Earth's atmosphere. In order to complement the above findings, we performed a wavelet analysis of SSA reconstructed time series, which agrees well with our earlier results and increases the signalto-noise ratio, thereby showing the strong influence of solargeomagnetic activity and ENSO throughout the entire period. The solar flares are considered responsible for causing the atmospheric circulation patterns. The net effect of solargeomagnetic processes on the temperature record might suggest counteracting influences on shorter (about 5-6-year) and longer (about 11-12-year) timescales. The present analyses suggest that the influence of solar activities on the Indian temperature variability operates in part indirectly through coupling of ENSO on multilateral timescales. The analyses, hence, provide credible evidence of teleconnections of tropical Pacific climatic variability and Indian climate ranging from inter-annual to decadal timescales and also suggest the possible role of exogenic triggering in reorganizing the global Earth-ocean-atmospheric systems.
