The Sensitivity of the African-Asian Monsoonal Climate to Orbital Parameter Changes for 9000 Years B.P. in a Low-Resolution General Circulation Model
Publisher: American Meteorological Society
Abstract: The earth's orbital parameters, precession, obliquity and eccentricity, produce solar radiation differences (compared to present) of ?7% at the solstices 9000 years before present (B.P.): more radiation in June-July-August, ...
Variance Spectrum of Holocene Climatic Fluctuations in the North Atlantic Sector
Publisher: American Meteorological Society
Abstract: The general character of the variance spectrum of temperature fluctuations on time scales from 1 to 10,000 years is estimated from a combination of botanical, chemical, historical and instrumental records from locations ...
Assessing Global Vegetation–Climate Feedbacks from Observations
Publisher: American Meteorological Society
Abstract: The feedback between global vegetation greenness and surface air temperature and precipitation is assessed using remote sensing observations of monthly fraction of photosynthetically active radiation (FPAR) for 1982 to ...
Coupled Climate Simulation of the Evolution of Global Monsoons in the Holocene
Publisher: American Meteorological Society
Abstract: Evolution of global monsoons in the Holocene is simulated in a coupled climate model?the Fast Ocean Atmosphere Model?and is also compared with the simulations in another coupled climate model?the NCAR Climate System Model. ...
Intercomparison of Simulated Global Vegetation Distributions in Response to 6 kyr BP Orbital Forcing
Publisher: American Meteorological Society
Abstract: The response of ten atmospheric general circulation models to orbital forcing at 6 kyr BP has been investigated using the BIOME model, which predicts equilibrium vegetation distribution, as a diagnostic. Several common ...
