“…The most prominent, at 90 yr, can be attributed to the 88-yr Gleissberg solar cycle (e.g. Gleissberg, 1944;Stuiver and Braziunas, 1993;Hoyt and Schatten, 1997) that has previously been recorded in several glacial (Anderson and Koopmans, 1963;Vos et al, 1997;Prasad et al, 2004) and interglacial varve time series (Anderson and Koopmans, 1963;Vos et al, 1997;Dean et al, 2002;Brauer et al, 2008). The 25-and 10.5-yr peaks from Dethlingen may correlate to the 22-yr Hale and 11-yr Schwabe solar cycles, respectively (e.g.…”

“…The 25-and 10.5-yr peaks from Dethlingen may correlate to the 22-yr Hale and 11-yr Schwabe solar cycles, respectively (e.g. Hoyt and Schatten, 1997) that have also been widely found in Quaternary varve time series of glacial (Anderson, 1961;Anderson and Koopmans, 1963;Vos et al, 1997;Rittenour et al, 2000) and interglacial origin (Anderson, 1961(Anderson, , 1992Anderson and Koopmans, 1963;Zolitschka, 1992;Vos et al, 1997;Livingstone and Hajdas, 2001;Dean et al, 2002;Theissen et al, 2008). The statistically significant expression of all three prominent decadal-scale solar cycles makes the Dethlingen varve record unique because most known varve records only contain evidence for one or two of these cycles, probably because of insufficient sensitivity of each individual lake's sedimentological properties to record the solar magnetic modulation (e.g.…”

“…Deeper insights into these processes have been gained through the time series analysis of varve thickness datasets; such efforts have successfully linked cyclical patterns in lake sediments with short-term natural periodic climate forcing (e.g. Anderson and Koopmans, 1963;Anderson, 1992;Zolitschka, 1992;Vos et al, 1997;Rittenour et al, 2000;Livingstone and Hajdas, 2001).

Abstract.To unravel the short-term climate variability during Marine Isotope Stage (MIS) 11, which represents a close analogue to the Holocene with regard to orbital boundary conditions, we performed microfacies and time series analyses on a ∼3200-yr-long record of annually laminated Holsteinian lake sediments from Dethlingen, northern Germany. These biogenic varves comprise two sub-layers: a light sub-layer, which is controlled by spring/summer diatom blooms, and a dark sub-layer consisting mainly of amorphous organic matter and fragmented diatom frustules deposited during autumn/winter. Time series analyses were performed on the thickness of the light and dark sub-layers. Signals exceeding the 95 % and 99 % confidence levels occur at periods that are near-identical to those known from modern instrumental data and Holocene palaeoclimatic records. Spectral peaks at periods of 90, 25, and 10.5 yr are likely associated with the 88-, 22-and 11-yr solar cycles, respectively. This variability is mainly expressed in the light sublayer spectra, suggesting solar influence on the palaeoproductivity of the lake. Significant signals at periods between 3 and 5 yr and at ∼6 yr are strongest expressed in the dark sub-layer spectra and may reflect an influence of the El Niño-Correspondence to: A. Koutsodendris (koutsodendris@em.uni-frankfurt.de) Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO) during autumn/winter. Our results suggest that solar forcing and ENSO/NAO-like variability influenced central European climate during MIS 11 similarly to the present interglacial, thus demonstrating the comparability of the two interglacial periods at sub-decadal to decadal timescales.

T he debate on the cause and the amount of global warming and its effect on global climates and economics continues. As world population continues its exponential growth, the potential for catastrophic effects from climate change increases. One previously neglected key to understanding global climate change may be found in examining events of world history and their connection to climate fluctuations.Climate fluctuations have long been noted as being cyclical in nature, and many papers have been published on this topic (1). These fluctuations also can be quite abrupt (2) when climate displays a surprisingly fast transition from one state to another. Possible causes of the cyclic variations and abrupt transitions at different time intervals have been theorized. These theories include internal drivers such as CO 2 concentrations (3), ocean temperature and salinity properties (4), as well as volcanism and atmospheric-transmissivity variations (5). External drivers include astronomical factors such as the Milankovitch orbital parameters (6), which recently have been challenged (7), and variations in the Sun's energy output (8-10).The most direct mechanism for climate change would be a decrease or increase in the total amount of radiant energy reaching the Earth. Because only the orbital eccentricity aspect of the Milankovitch theory can account for a change in the total global energy and this change is of the order of only a maximum of 0.1% (11), one must look to the Sun as a possible source of larger energy fluctuations. Earth-satellite measurements in the last two decades have revealed that the total energy reaching the Earth varies by at least 0.1% over the 10-to 11-year solar cycle (12). Evidence of larger and longer term variations in solar output can be deduced from geophysical data (13-17).In an extensive search of the literature pertaining to geophysical and astronomical cycles ranging from seconds to millions of years, Perry (18) demonstrated that the reported cycles fell into a recognizable pattern when standardized according to fundamental harmonics. An analysis of the distribution of 256 reported cycles, when standardized by dividing the length of each cycle, in years, by 2 N (where N is a positive or negative integer) until the cycle length fell into a range of 7.5 to 15 years, showed a central tendency of 11.1 years. The average sunspot-cycle length for the period 1700 to 1969 is also 11.1 years (19). In fact, the distribution of the sunspot cycles is very nearly the same as the distribution of the fundamental cycles of other geophysical and astronomical cycles. Aperiodicity of the cycles was evident in two side modes of 9.9 and 12.2 years for the geophysical and astronomical cycles and 10.0 and 12.1 years for the sunspot cycle. The coincidence of these two patterns suggests that solar-activity cycles and their fundamental harmonics may be the underlying cause of many climatic cycles that are preserved in the geophysical record. Gauthier (20) noted a similar unified structure in Quaternary climate data...

Phase coherence and phase jumps in the Schwabe cycle

et al. 2020

View full text Add to dashboard Cite

Guided by the working hypothesis that the Schwabe cycle of solar activity is synchronized by the 11.07‐year alignment cycle of the tidally dominant planets Venus, Earth, and Jupiter, we reconsider the phase diagrams of sediment accumulation rates in Lake Holzmaar and of methanesulfonate data in the Greenland ice core Greenland Ice Sheet Project 2 (GISP2), which are available for the period 10000–9000 cal. BP. As some half‐cycle phase jumps appearing in the output signals are, very likely, artifacts of applying a biologically substantiated transfer function, the underlying solar input signal with a dominant 11.04‐year periodicity can be considered to be mainly phase‐coherent over the 1,000‐year period in the early Holocene. For more recent times, we show that the reintroduction of a hypothesized “lost cycle” at the beginning of the Dalton minimum would lead to a real phase jump. Similarly, by analyzing various series of 14C and 10Be data and comparing them with Schove's historical cycle maxima, we support the existence of another “lost cycle” around 1565, also connected with a real phase jump. Viewed synoptically, our results lend greater plausibility to the starting hypothesis of a tidally synchronized solar cycle, which at times can undergo phase jumps, although the competing explanation in terms of a nonlinear solar dynamo with increased coherence cannot be completely ruled out.
