The locally accumulated damage by tropical cyclones (TCs) can intensify substantially when these cyclones move more slowly.While some observational evidence suggests that TC motion might have slowed significantly since the mid-20th century ([ 1 ]),the robustness of the observed trend and its relation to anthropogenic warming have not been firmly established ([ 2 ][ 4 ]).Tree-ring 18O based PDSI reconstruction in the Mt.Tianmu Sep 01,2019 Download Climate TimeseriesSAM from 20CR V2C NOAA#0183;Previous studies on tree-ring stable oxygen isotopes ( 18 O) in the monsoon region of China have rarely involved in variations of the East Asian summer monsoon (EASM) and its rainbelt.In this study,a tree-ring 18 O chronology of Cryptomeria fortune at Mt.Tianmu,located south of the Yangtze River lower reaches,was developed and applied to reconstruct the local JuneOctoberThe steady enhancement of the Australian SummerNov 23,2017 Download Climate TimeseriesSAM from 20CR V2C NOAA#0183;We have also used this series to examine the performance of AUSMI-like dynamical indices computed from data from the NOAA-CIRES Twentieth Century Reanalysis Project version 2c (20CR-V2c),covering
