Temporal and spatial patterns of Holocene dune activity on the Great Plains of North America: megadroughts and climate links
TL;DR: The Holocene record of eolian sand and loess deposition is reviewed for numerous presently stabilized dune fields on the Great Plains of North America in this paper, showing that dune field activity reflects decade-to-century-scale dominance of drought with a growing season deficit of precipitation > 25%.
Journal ArticleDOI
Soil Moisture and the Persistence of North American Drought
TL;DR: In this paper, the effects of soil moisture on North American summertime climate were performed using a 12-layer global atmospheric general circulation model, and it was found that a reduction in soil moisture leads to an increase in surface temperature, lower surface pressure, increased ridging aloft, and a northward shift of the jet stream.
Journal ArticleDOI
Weakening of Indian Summer Monsoon Rainfall due to Changes in Land Use Land Cover.

TL;DR: It is found that deforestation results in weakening of the ISMR because of the decrease in evapotranspiration and subsequent decrease in the recycled component of precipitation.
Journal ArticleDOI
Lake sediments record large-scale shifts in moisture regimes across the northern prairies of North America during the past two millennia

TL;DR: Six high-resolution climatic reconstructions, based on diatom analyses from lake sediment cores from the northern prairies of North America, show that shifts in drought conditions on decadal through multicentennial scales have prevailed in this region for at least the last two millennia.
Journal ArticleDOI
Middle east climate simulation and dominant precipitation processes
TL;DR: The ability of both the ECMWF-TOGA analyses and regional model RegCM2 to simulate the climate of the Middle East is examined in this article, where it is shown that accurate simulation of precipitation in these regions requires the correct simulation of storm tracks, topographic interactions and atmospheric stability.
