| 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。 |
| 英文摘要: |
| 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. |
