Spatio-temporal distribution of internal waves in the Andaman Sea based on satellite remote sensing

In this paper, More than 1000 satellite images including Terra/Aqua MODIS, Sentinel-1A SAR images from 2013 to 2015 were analyzed to obtain spatio-temporal distribution of internal waves in the Andaman Sea. The statistical results demonstrate that the internal wave have been observed mostly in four areas by the remote sensing: northern Sumatra Island, western Malay Peninsula, northeast of the Nicole Islands and eastern Andaman Islands in Andaman Sea. Internal waves in the middle and the gradually changing bathymetric gradients areas of the Andaman Sea have been unobserved by the remote sensing. Internal waves can be observed in Andaman Sea all through the year, most in hot season (February to April), next rainy season( May to October). And a minimum number of internal waves are observed in rainy(June to August), however, this may be caused by the small amount of clear MODIS images in rainy in the Andaman Sea, it need to further proof by using more remote sensing images.
