RISHistorical SAM Variability. Part I: Century-Length Seasonal Reconstructions
Publisher: American Meteorological Society
Abstract: Seasonal reconstructions of the Southern Hemisphere annular mode (SAM) index are derived to extend the record before the reanalysis period, using station sea level pressure (SLP) data as predictors. Two reconstructions ...
Identifying Signatures of Natural Climate Variability in Time Series of Global-Mean Surface Temperature: Methodology and Insights
Publisher: American Meteorological Society
Abstract: Global-mean surface temperature is affected by both natural variability and anthropogenic forcing. This study is concerned with identifying and removing from global-mean temperatures the signatures of natural climate ...
A Further Extension of the Tahiti-Darwin SOI, Early ENSO Events and Darwin Pressure
Publisher: American Meteorological Society
Abstract: An extension of the Tahiti minus Darwin Southern Oscillation Index (SOI) from 1882 back to 1876 is reported following the recovery of early Darwin mean sea-level pressure data spanning the period 1865?81. As a result, we ...
The SCAR READER Project: Toward a High-Quality Database of Mean Antarctic Meteorological Observations
Publisher: American Meteorological Society
Abstract: A new dataset of monthly and annual mean near-surface climate data (temperature, surface and mean sea level pressure, and wind speed) for the Antarctic region has been created using historical observations [Scientific ...
