“…1610-1670. These changes are similar to changes Environ Earth Sci in temperature regimes reconstructed from lake bottom sediments and soil sequences from other areas of Central Asia (Yang et al 2002;Kalugin et al 2009;Zhu et al 2012;Ge et al 2013). However, an ice core oxygen isotopic record retrieved from the Belukha glacier (the Siberian Altai, West Siberia), located ca.…”

“…However, empirical reconstructions (the model ECHO-G) of the NH temperature evidenced that annual temperature dramatically decreased after ca. 1550 (Storch et al 2004) as well as in West Siberia (Kalugin et al 2009) and China (Anderson et al 2002;Yang et al 2002). Central Asian temperature records clearly evidenced that in the last 850 years the regional summer temperature minimum occurred about 1650 (Fig.…”

A 850-year record climate and vegetation changes in East Siberia (Russia), inferred from geochemical and biological proxies of lake sediments

East Siberia is very sensitive to moisture regimes because it is located in a margin area, where moisture from the North Atlantic is strongly depleted, and the penetration of the East Asian monsoon is weak and rare. In winter months, the Siberian anticyclone strongly blocks and reduces the external influences on the region. The high latitude of the study area at 52°N is probably sensitive to variation in insolation and solar activity. We analysed a 42-cm-long sediment record from Lake Mountain located in East Siberia (Russia) for geochemical, mineralogical, subfossil diatoms, chironomids, and pollen to provide a reconstruction of the climate history of the area for the last 850 years. According to our reconstruction, a clear decrease in summer temperatures occurred in East Siberia after ca. 1400 and we linked this temperature drop with the beginning of the Little Ice Age. The coldest summer occurred about ca. 1570-1700 and 1830-1900. We assumed that the most significant changes of the lake bio-productivity and the catchment area were occurred about ca.

“…A 6-year cyclicity of decreased and increased fire hazard in the forests of Gornyi Altai was reported in [21]. Data of paleoreconstruction of different types [22,23] showed that in the course of the Holocene the region under consideration experienced repeated fluctuations of climate coinciding with the main global tendencies and similar in the rate of variation with current warming; furthermore, a coincidence of the cooling phases with low SA is pointed out.…”

An analysis is made of the temperature dynamics using current data from stations in the Altai region. The study revealed that the climatic characteristics in the region undergo synchronous changes. The synchronicity in changes of the components of temperature series for all the stations under consideration is characterized by a high connectivity of each of the components with a corresponding type field. It is found that a part of the variability of the temperature series described by hidden periodicities averages 1.3%, and this is much larger than the influence of trends which does not exceed 0.3% for most of the stations. The largest contribution to temperature variations in the Altai region is made by harmonics with a period of 20 years (mean annual), 40 and 9 years (winter), 18 years (summer), and 5-8 years (autumn, spring). A long-term forecast of air temperature changes in the region into 2030 is made.

Multispectral analysis of Northern Hemisphere temperature records over the last five millennia

Aiming to describe spatio-temporal climate variability on decadal-to-centennial time scales and longer, we analyzed a data set of 26 proxy records extending back 1000 to 5000 years; all records chosen were calibrated to yield temperatures. The seven irregularly sampled series in the data set were interpolated to a regular grid by optimized methods and then two advanced spectral methods -namely singular-spectrum analysis (SSA) and the continuous wavelet transform -were applied to individual series to separate significant oscillations from the high noise background. This univariate analysis identified several common periods across many of the 26 proxy records: a millennial trend, as well as oscillations of about 100 and 200 yr, and a broad peak in the 40-70-yr band. To study common NH oscillations, we then applied Multichannel SSA (MSSA). Temperature variations on time scales longer than 600 yr appear in our analysis as a dominant trend component, which shows climate features consistent with the Medieval Warm Period and the Little Ice Age. Statistically significant NH-wide peaks appear at 330, 250 and 110 yr, as well as in a broad 50-80-yr band. Strong variability centers in several bands are located around the North Atlantic basin and are in phase opposition between Greenland and Western Europe.
