RISAtlantic Control of the Late Nineteenth-Century Sahel Humid Period
Publisher: American Meteorological Society
Abstract: AbstractPrecipitation regime shifts in the Sahel region have dramatic humanitarian and economic consequences such as the severe droughts during the 1970s and 1980s. Though Sahel precipitation changes during the late twentieth ...
Mechanisms of Mid-Holocene Precipitation Change in the South Pacific Convergence Zone
Publisher: American Meteorological Society
Abstract: he variability of the South Pacific convergence zone (SPCZ) during the mid-Holocene is investigated using models archived in the Paleoclimate Modelling Intercomparison Project Phase II (PMIP2) database. Relative to ...
Spatiotemporal Variability of the South Pacific Convergence Zone Fresh Pool Eastern Front from Coral-Derived Surface Salinity Data
Publisher: American Meteorological Society
Abstract: AbstractDirect observations indicate a southeastward expansion of the South Pacific convergence zone (SPCZ) fresh pool and a freshening trend since the 1970s. Understanding decadal and longer-term variability of the SPCZ ...
Progress in Paleoclimate Modeling
Publisher: American Meteorological Society
Abstract: This paper briefly surveys areas of paleoclimate modeling notable for recent progress. New ideas, including hypotheses giving a pivotal role to sea ice, have revitalized the low-order models used to simulate the time ...
