Droughts on the Tibetan plateau coincide with grand solar minima

May 14, 2012

Yet another paper indicating that climate and solar behaviour are related – at least over the Tibetan plateau and at least over the last 1000 years.

Tree ring based precipitation reconstruction in the south slope of the middle Qilian Mountains, northeastern Tibetan Plateau, over the last millennium

Reconstruction of precipitation amounts for the edge of the Tibet Plateau. The bars on the chart depict prominent weak phases of solar activity, which correspond to Om = Oort Minimum; Wm = Wolf Minimum; Sm = Spörer Minimum; Mm = Maunder Minimum; Dm = Dalton Minimum). Figure from: Sun & Liu (2012).

Geologist Dr. Sebastian Lüning and chemist Prof. Fritz Vahrenholt have written a summary of this paper (in German), and this translation is from P Gosselin at NoTricksZone

New Study of the Tibet Plateau: Whenever Solar Activity is Weak, the Rains Disappear
By Sebastian Lüning and Fritz Vahrenholt

The Tibet Plateau is at 3000 to 5000 meters elevation and is the highest and (most) expansive high plateau on Earth. Therefore it reacts sensitively to climate changes. Junyan Sun and Yu Liu of the Chinese Academy of Sciences studied tree rings in the northwest plateau edge from two living 1000 year old trees. Tree growth in the area of study is particularly sensitive to the amount of precipitation. (more…)
