Abstract: Based on daily data from NCEP/NCAR reanalysis for 1948/1949–2015/2016 winters (November through March), this study examines the physical nature of the Arctic Oscillation (AO). Results show that the AO events derived from the daily AO… read more here.

DOI: 10.1007/s13131-017-1025-z
Abstract: The Arctic near-surface air temperatures are increasing more than twice as fast as the global average–a feature known as Arctic amplification (AA). A modified AA index is constructed in this paper to emphasize the contrast… read more here.

DOI: 10.3390/atmos12050538
Abstract: In recent decades, extremely cold winters have occurred repeatedly throughout the Northern Hemisphere, including the Korean Peninsula (hereafter, Korea). Typically, cold winter temperatures in Korea can be linked to the strengthening of the Siberian High… read more here.
