چکیده

The precipitation climatology and the underlying climate mechanisms of the eastern Mediterranean, West Asia, and the Indian subcontinent are reviewed, with emphasis on upper and middle tropospheric flow in the subtropics and its steering of precipitation. Holocene climate change of the region is summarized from proxy records. The Indian monsoon weakened during the Holocene over its northernmost region, the Ganges and Indus catchments and the western Arabian Sea. Southern regions, the Indian Peninsula, do not show a reduction, but an increase of summer monsoon rain across the Holocene. The long-term trend towards drier conditions in the eastern Mediterranean can be linked to a regionally complex monsoon evolution. Abrupt climate change events, such as the widespread droughts around 8200, 5200 and 4200 cal yr BP, are suggested to be the result of altered subtropical upper-level flow over the eastern Mediterranean and Asia. The abrupt climate change events of the Holocene radically altered precipitation, fundamental for cereal agriculture, across the expanse of late prehistoric–early historic cultures known from the archaeological record in these regions. Social adaptations to reduced agro-production, in both dry-farming and irrigation agriculture regions, are visible in the archaeological record during each abrupt climate change event in West Asia. Chronological refinement, in both the paleoclimate and archaeological records, and transfer functions for both precipitation and agro-production are needed to understand precisely the evident causal linkages. © 2006 University of Washington.

On the Possible Correlation between the Collapse of Sialk IV and Climatological Events during the Middle–Late Holocene

Prehistoric archaeological sites in the center of the Iranian Plateau suddenly disappeared around the end of the 4th millennium BCE. At Tepe Sialk, near Kashan, the last cultural period, namely Sialk IV - probably established around 3400 BCE after the last settlements of Sialk III6-7b - was abandoned approximately after 500 years. The material culture of this period, known as Proto-Elamite peri...

The site of Kul Tepe is located near the city of Hadishahr, in Eastern Azerbaijan Province. It is an ancient multi-period mound, having an extension of about 6 hectares and rising 19 meters above the surrounding land. The second season of archeological excavations at the site, carried out in 2013, aimed at clarifying its chronology and its settlement organization. In the meantime it aimed at el...

Holocene moisture evolution in arid central Asia and its out-of-phase relationship with Asian monsoon history

We synthesize palaeoclimate records from the mid-latitude arid Asian region dominated today by the Westerlies (‘‘arid central Asia’’ (ACA)) to evaluate spatial and temporal patterns of moisture changes during the Holocene. Sediment records from 11 lakes with reliable chronologies and robust proxies were selected to reconstruct moisture histories based on a five-class ordinal wetness index with ...

Environmental change and cultural dynamics of Holocene hunteregatherers in Northeast Asia: Comparative analyses and research potentials in Cis-Baikal (Siberia, Russia) and Hokkaido (Japan)

While substantial progress has been achieved in hunteregatherer research over the last century, it is still the case that the understanding of the cultural dynamism, variability, and resilience of Holocene hunteregatherers remains rather impoverished. Emerging archaeological insights suggest that the prehistory of many forager societies included periods of sudden cultural transformation, marked...

[1] A Holocene Gulf of Guinea record of riverine runoff, based on Ba/Ca in tests of a shallow-dwelling planktic foraminifer, and sea surface temperature (SST), based on Mg/Ca, reveals centennial-scale instabilities in West African monsoon (WAM) precipitation and eastern equatorial Atlantic (EEA) thermal conditions. The long-term Holocene climate trend is characterized by a warm and wet early-mi...
