General Circulation & Principal Wave Modes in Andaman Sea. Fluid Dynamics of Andaman Sea from Observations

      Аннотация: This book introduces you to the realm of physical oceanography of Andaman Sea with the application of simple tools of data analysis. It draws insight into the general circulation of the covert oceanic domain, which was seldom explored in earlier expeditions. Intense down welling occurs to the north coast of Indonesia during Summer, locally forced by south-westerlies. According to the study, Equatorial Wyrtki jets remotely force Kelvin waves of downwelling nature in the basin during April and October. Further, it throws light on the baroclinic wave modes which affect its dynamics. The circulation in Andaman Sea is characterised by gyres or vortices, which is the manifestation of Rossby waves of semi-annual mode. The basin has a characteristic 120-day mode of westward propagating long Rossby wave packets which reflect off the coast of ANI as eastward propagating short Rossby waves.
