摘要/Abstract

摘要： 安达曼海是内波频繁发生的海区之一,对其内波的研究是当今海洋研究的热点。本文利用2013—2016年间覆盖整个安达曼海的3 000多幅Terra/Aqua MODIS、GF-1、Landsat-8、Sentinel-1 等卫星遥感图像,从中提取和解译了内波波列线和波向信息,得到安达曼海海洋内波的时间分布特征,并绘制了内波空间分布图。结果表明,安达曼海及其邻近海域内波主要出现在4个区域:苏门答腊岛以北海域、安达曼海中部海域、安达曼海北部海域以及尼科巴群岛以西海域,尺度较大的内波主要分布在苏门答腊岛以北海域和安达曼海中部海域。在时间分布上,2013—2016年间安达曼海内波的年发生次数相近;在热季、雨季及冬季遥感都能观测到内波的发生;2-4月遥感观测到的内波最多,其次为8、9月,7月遥感观测到的内波较少,这可能是由于雨季光学影像受云影响,安达曼海海域晴空影像过少造成,还需要借助更多的遥感影像进一步证明。在波向上,安达曼海多数内波向岸传播,在苏门答腊岛北部、安达曼海中部海域,内波向东或向东南传播;在安达曼群岛东部,内波向东传播,传播一定距离后与海底地形交互作用,一部分继续向前传播,一部分产生反射,向西南方向传播至安达曼群岛;在尼科巴群岛以西海域,内波由尼科巴群岛向孟加拉湾传播。

Abstract: Internal waves occur frequently in Andaman Sea, and the study of its internal waves is the hotspot of ocean research today. In this study, more than 3 000 Terra/Aqua MODIS, GF-1, Landsat-8 and Sentinel-1 satellite remote sensing images covering the entire Andaman Sea from 2013 to 2016 were analyzed to obtain spatial and temporal distribution and wave direction feature of internal waves in the Andaman Sea. The statistical result shows that internal waves can be observed by the remote sensing mostly in four areas: north of Sumatra Island, middle of the Andaman Sea, north of the Andaman Sea and west of Nicobar Islands. The internal waves with a relative large spatial scale in northern Sumatra and middle of the Andaman Sea are more active in the Andaman Sea. No internal waves in the deep sea and the gradually changing bathymetric gradients areas of the Andaman Sea have been observed by the remote sensing. The distribution of observed internal waves is similar each year from 2013 to 2016 in the Andaman Sea. Internal waves can be observed in the Andaman Sea all through the year, most in February to April (hot season), next in August and September (rainy season), A minimum number of internal waves are observed in June, however, this may be caused by the small amount of clear optical images in rainy season in the Andaman Sea, it needs to further prove by using more remote sensing images. From the directions distribution, most internal waves propagate to the coast. Internal waves propagate eastward or southeastward in north of Sumatra Island and middle of the Andaman Sea, southeastward or southwestward in eastern Andaman Island. In addition, we found some internal waves propagate from the Andaman Sea to the Bay of Bengal.

Key words: Andaman Sea, internal waves, remote sensing, spatial-temporal distribution, wave direction
