Abstract: AbstractThe winter Arctic atmosphere in the middle and lower troposphere has shifted to a warmer stage since the winter of 2004/05 relative to the mean averaged from 1979/80 to 2003/04. Recent Arctic warm anomalies are ...

Abstract: During recent years, the rapidly warming Arctic and its impact on winter weather and climate variability in the mid- and low latitudes have been the focus of many research efforts. In contrast, anomalous cool Arctic summers ...

Abstract: AbstractThrough both observational analyses and simulation experiments, this study investigates the intraseasonal evolution of atmospheric circulation anomalies associated with a persistent cold event in the Asian continent ...

Abstract: Using monthly Arctic sea ice concentration data (1953?95) and the National Centers for Environmental Prediction?National Center for Atmospheric Research (NCEP?NCAR) reanalysis dataset (1958?99), possible feedbacks of sea ...

Abstract: Two distinct modes of the East Asian winter monsoon (EAWM) have been identified, and they correspond to real and imaginary parts of the leading mode of the EAWM, respectively. Analyses of these modes used the National ...

Abstract: This paper identified an atmospheric circulation anomaly?dipole structure anomaly in the Arctic atmosphere and its relationship with winter sea ice motion, based on the International Arctic Buoy Program (IABP) dataset ...

Abstract: his paper describes two dominant patterns of Asian winter climate variability: the Siberian high (SH) pattern and the Asia?Arctic (AA) pattern. The former depicts atmospheric variability closely associated with the intensity ...

Abstract: Resolution of a complex Hermitian matrix derived from monthly mean 850-hPa wind fields during the summer season (June?August) from 1968 to 2004 revealed four different modes of East Asian summer monsoon (EASM) variability. ...
