“…In particular, the $60-year cycle manifests itself as the rotation of cold and warm epochs in the Arctic Frolov et al, 2009). A similar periodicity was found in the oscillations of sea level pressure at polar latitudes, the so called Arctic Oscillation (Veretenenko and Ogurtsov, 2014). Thus, the 60-70-year oscillations in Taymir and Yamal temperatures agree with the climatic variations reported earlier in the Arctic region.…”

“…Furthermore, reconstructed dry–wet cycles in West China and the interior of North America in the late Holocene are well‐correlated with solar activity cycles, as demonstrated by atmospheric 14 C concentrations (Reimer et al, ; Wu et al, ; Z. C. Yu, Ito, Engstrom, & Fritz, ). In response to solar activity, the phase of the Arctic oscillation changes and is characterized by low‐ (high‐) pressure anomalies in polar (mid‐) latitude regions (Veretenenko & Ogurtsov, ). The positive phase of the Arctic oscillation under low solar activity is accompanied by the strengthening of westerly winds at mid‐latitudes, which shift their pattern northward over East Asia.…”

Detailed diatom records within core sediments from Maeho Lagoon along the Eastern coast of South Korea revealed that the ecological dynamics of the lagoon during the Holocene were associated with relative sea level and regional precipitation. Accelerator mass spectrometry (AMS) 14C dating indicates that sediment accumulation began prior to 8300 cal. year BP, and that the lagoon formed around 8000 cal. year BP. The salinity level of the lagoon increased until 5000 cal. year BP, and then decreased. Long‐term trends in salinity were dependent upon changes in sea level: periods of high salinity in the lagoon were generally coincident with periods of high sea levels along the east coasts of Korea and Japan. On the other hand, multicentennial‐scale fluctuations in diatom assemblages and magnetic susceptibility (MS) suggest that a 400 year fluctuation in salinity was regulated by changes in precipitation in the area of this lagoon. Changes in the westerly jet stream, controlled by variation in solar irradiance, had an important influence on precipitation volume in South Korea, suggesting that the patterns of the westerly jet stream fluctuate on a 400 year cycle.

“…6B, D, F) document regular and persistent coherence variations at the level of the c. 60-70-year cycle (50-80-year band), contrasting with the transient nature of the coherence at the quasi-bi-decadal scale. These synchronized periodicities (with a coherence coefficient of ≥0.7) at c. 64 years can be linked to evidence of a roughly 60-year periodicity in the strength of the stratospheric polar cyclonic vortex (Veretenenko & Ogurtsov 2014) in association with reported signs of the Gleissberg cycle at both NH high latitudes (Ogurtsov et al 2015) and mid-latitudes (Moffa-S anchez et al 2014). Thus, longer-term solar modulation (Lower Gleissberg band) of the NAO/AO pattern regulating the temperature/precipitation regime in the EDM region and affecting the Caminha salt marsh hydrological balance (see Fig.…”

This work presents two novel climate-related time series for the northwest of Portugal. The first is an AD 1626-1820 triennial-resolvedwine production series, based on the Benedictine accounts from six monasteries of the Entre-Douroe-Minho (EDM) region. The second, an AD 1654-2010 benthic foraminiferal record from the Caminha salt marsh, located in the lowerestuaryof the MinhoRiver. The serieswereanalysedtogether for the common periodto outlinehow both palaeoclimatic proxies respond to the most likely natural environmental drivers of temporal variability, solar forcing included. Singular spectral analysis revealed a common significant multidecadal periodicity agreeing with recognized long-term changes in solar activity, i.e. the Lower Gleissberg cycle (50-80 years). The application of wavelet analysis allowed the detection of high coherence at this time scale (centred at c. 64 years) between marsh foraminifera and both total solar irradiance and the North Atlantic Oscillation index. This relationship persists throughout the c. AD 1730-1875period. The continuouswavelettransform results for wine productionwereinconclusive. As the timespan analysed is recognized as one of high socio-economic and political distress, the main human-driven impacts on wine production, particularly in the two periods of greatly reduced solar activitythe Maunder and Dalton Minimaare reviewed in the light of the available historical records. In addition to a documented climate-related agricultural crisis in Portugal, damage and losses to wine production may have been triggered by several local and international conflicts in which the country was involved. But to what extent the two influences contributed to the wine production variations observed in the EDM region during both periods remains an open question.
