中文摘要：

暴风雨(SDS ) 天气从 1980 ～ 2011 在东北亚洲上处理的地区性的沙灰尘的典型分布用气象学的数据，大气的发出声音数据，中国高密度天气数据， NCEP/NCAR 分析数据，以及转存的原版捱过的分享的世界气象组织表面车站被调查中国的地图。集中加权的轨道(享特威) 方法被用来从分离车站数据计算 SDS 频率并且在东北亚洲追踪大规模地区性的 SDS 天气进程。一个花键趋势分析方法被采用调查 SDS 天气系统的可变性。结果证明在 19802011 期间， SDS 天气过程与近似 10 年的高度低的出现摆动展出历史的坚持和突然的转变。通过大气的循环的合成分析在高、低的 SDS 年期间， SDS 出现是，这被发现仔细与北极旋涡和 midlatitude 的异例有关西，并且在湖贝加尔湖附近的发行量模式。在高频率年期间， meridianal 在东亚在高 SDS 走廊上面流动在上面、中间的对流层(从沿着西北和诺思中国，朝鲜半岛，和日本岛的巴尔克哈什湖)比 meridianal 流动在低 SDS 频率年期间的显然强壮，在 midlatitude 区域赞成 SDS 的发展和运输。

英文摘要：

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, meridianal flows during the low SDS frequency years, the midlatitude regions. and Japan Islands） are apparently stronger than the favoring the development and transport of SDSs in the midlatitude regions.
