| Abstract: |
| In this study, about 220 satellite images between 2000 and 2012 were obtained from FY-series, MODIS, CBERS, HJ-1A and HJ-1B to estimate the impact of duststorms on the South Yellow Sea (SYS), which serve as an important source of particles there. The analyzing results from the images support a total occurrence of 88 duststorms (including the locally-generated dusty weather) that affected the SYS during 2000-2012. The annual occurrence was about 4-10 times (10 times in 2000 and 2004; four times in 2009 and 2012), predominantly in March (29%), April (33%) and May (22%). By mapping the distribution of their frequency, the duststorms influencing the SYS were found primarily moving from the northwest (39 times, 44.3%) and west (37 times, 42%) to the study region with only 11 duststorms (12.5%) coming from the north and 1 duststorm (1%) from the southwest. We estimated that an annual amount of 0.5-3.5 million tons of sediment particles was brought to the SYS by the duststorms during 2000-2012. |

| 本文采用2000-2012年间大约220幅的风云系列，MODIS，中巴卫星，环境-1A和环境-1B卫星遥感数据，估算南黄海重要的颗粒物来源之一，沙尘暴对黄海沉积量的贡献。在对这些卫星数据进行统计发现，2000-2012年间，总共有88次沙尘暴（包括本地沙尘天气）影响到南黄海，每年有4-10次（其中，2000年和2004年10次，2009年和2012年4次），主要发生在3月（29%）、4月（33%）和5月（22%）。从沙尘进入南黄海的方向来看，主要从西北（39次，44.3%）和西部（其中37次，42%），而从北部（11次，12.5%）和西南（1次，1%）进入南黄海的次数相对较少。结合相应的算法对这些卫星数据进行处理后估算，在2000-2012年间，每年由沙尘带给南黄海的可沉积颗粒物大约0.5-3.5百万吨。 |
