Dec 18,2011·A central paradox of the global monsoon record involves reported decreases in rainfall over land during an era in which the global hydrologic cycle is both expected and observed to intensify.It is within this context that this work develops a physical basis for both interpreting the observed record and anticipating changes in the monsoons in a warming climate while bolstering the concept of APDRC Datadoc NOAA-CIRES-DOE 20th Century ReanalysisNOAA-CIRES-DOE 20th Century Reanalysis V3 contains objectively-analyzed 4-dimensional weather maps and their uncertainty from the early 19th century to the 21st century.Using a state-of-the-art data assimilation system and surface pressure observations,the NOAA-CIRES-DOE Twentieth Century Reanalysis (20CR) project has generated a four-dimensional global atmospheric dataset of weatherAPDRC Datadoc NOAA/ESRL 20th Century Reanalysis V2 /NOAA/ESRL 20th Century Reanalysis V2 / V2c.Monolevels 6-hourly.The NCEP-NCAR Reanalysis product starts from 1948,leaving many important climate events such as 1930's dust bowl droughts uncovered.To expand the coverage of global gridded reanalyses,the 20th Century Reanalysis Project is an international effort led by Physical Science Division and the University of Colorado CIRES

Important features of the Atlantic meridional mode (AMM) are not fully understood.We still do not know what determines its dominant decadal variability or the complex physical processes that sustain it.Using reanalysis datasets,we investigated the influence of the North Atlantic Ocean variability on the dominant decadal periodicity that characterizes the AMM.Atmosphere Free Full-Text East Asian Summer Monsoon The National Centers for Environmental Predictions (NCEP)/National Center for Atmospheric Research (NCAR) Reanalysis (NCEPI; ) is the original re-analysis effort.Then NCEP/Department of Energy (DOE) updated the forecast model with better physical parameterisations and fixed the data assimilation errors to produce a new version of re-analysis Climate Prediction CenterThe 20th Century Reanalysis took another approach,and it made the time series more homogeneous by only assimilating surface pressure observations.Such a reanalysis is less accurate because it assimilates much fewer observations.The Climate Prediction Center (CPC) wanted a NCEP/NCAR Reanalysis (RI) replacement that would be between these
