Abstract
The characteristic distributions of regional sand-dust storm (SDS) weather processes over Northeast Asia
from 1980 to 2011 were investigated using the shared WMO surface station meteorological data, atmospheric
sounding data, China high density weather data, NCEP/NCAR reanalysis data, as well as the archived
original weather maps of China. The concentration-weighted trajectory (CWT) method was used to calculate
the SDS frequency from the discrete station data and to track the large-scale regional SDS weather processes
in Northeast Asia. A spline trend analysis method was employed to investigate the variability of the SDS
weather systems. The results show that during 1980–2011, the SDS weather processes exhibit both a
historical persistence and abrupt transitions with an approximate 10-yr high-low occurrence oscillation.
Through composite analysis of atmospheric circulation during high and low SDS years, it is found that
the SDS occurrences are closely related to the anomalies of arctic vortex and midlatitude westerly, and
the circulation patterns around the Lake Baikal. During the high frequency years, the meridianal flows
in the upper and mid troposphere above the high SDS corridor in East Asia (from the Lake Balkhash
along Northwest and North China, Korean Peninsula, and Japan Islands) are apparently stronger than the
meridianal flows during the low SDS frequency years, favoring the development and transport of SDSs in
the midlatitude regions.
