Understanding and modeling space-time Holocene climate variability

General Circulation Modelling of Holocene climate variability

Results from a series of Goddard Institute for Space Studies (GISS) General Circulation Models (GCMs) are used to assess climate variability in the pre-anthropogenic Holocene, the interval following the end of the last glacial beginning roughly 11.5 kyr BP. In particular, we focus on the forced aspects of this variability. The principle forcings are orbital, solar, volcanic and events (such as ...

Holocene climate variability in arid Asia: Nature and mechanisms

The papers in this special issue are derived from a selection of presentations given at the RACHAD workshop titled ‘‘Pattern of Holocene Climate Change in Central Asia: Data Synthesis’’ held at Lanzhou University, People’s Republic of China, from 25th to 27th July 2006. RACHAD is INQUA Palaeoclimate Commission (PALCOMM) Project (#0502), concerned with ‘rapid climate change in Central Asia’s dry...

Modeling the effect of freshwater pulses on the early Holocene climate: The influence of high-frequency climate variability

[1] The effect of freshwater pulses on the early Holocene climate is investigated with a global coupled atmosphere-sea iceocean model. In the model an early Holocene equilibrium climate state is perturbed by releasing a fixed amount of freshwater (4.67 10 m) into the Labrador Sea at three different constant rates: 1.5 Sv (1 Sv = 1 10 m s ) in 10 years, 0.75 Sv in 20 years, and 0.3 Sv in 50 year...
