Abstract: wo important dynamical processes influence the extratropical zonal wind field: angular momentum transport by the thermally direct Hadley circulation (thermal-driving T) and momentum flux convergence by atmospheric waves ...

Abstract: nternal variability in twenty-first-century summer Arctic sea ice loss and its relationship to the large-scale atmospheric circulation is investigated in a 39-member Community Climate System Model, version 3 (CCSM3) ensemble ...

Abstract: Month-to-month storm-track variability is investigated via EOF analyses performed on ERA-40 monthly-averaged high-pass filtered daily 850-hPa meridional heat flux and the variances of 300-hPa meridional wind and 500-hPa ...

Abstract: An analysis of detailed relationships between the North Atlantic Oscillation?Arctic Oscillation (NAO?AO) and local temperature response throughout the northeastern United States and neighboring areas of Canada is presented. ...

Abstract: A new approach is put forward for defining extratropical teleconnection patterns. The zonal wind field at 250 hPa is analyzed separately in the North Atlantic and North Pacific Ocean sectors during the winter season ...

Abstract: atterns of correlation between tree rings and local temperature or precipitation are investigated using 762 International Tree-Ring Data Bank standardized ring width site chronology time series, and a gridded dataset of ...

Abstract: he decline in Barents Sea ice has been implicated in forcing the ?warm-Arctic cold-Siberian? (WACS) anomaly pattern via enhanced turbulent heat flux (THF). This study investigates interannual variability in winter ...
