Analisis of intense internal wave evolution in the Sea of Japan and Okhotskoе Sea using satellite data from syntetic apertur radar and radiometers
The paper concerns investigation of internal wave (IW) dynamics in the areas of Okhotskoe Sea and the Sea of Japan by their surface manifestations recorded by MODIS radiometer (MODerate resolution Imaging Spectroradiometer) of the Terra and Aqua satellites and synthetic aperture radar ASAR of the Envisat satellite. Principal attention is focused on complex study of the dynamics of intense internal waves propagating in the shelf zone of the ocean. The analysis is based on the investigation of kinematic characteristics of surface manifestations of internal wave trains (wave fronts) and amplitude characteristics of the obtained SAR images. At the current stage of this research we have assessed different mechanisms of surface IW events, and calculated their linear kinematic characteristics under assumption of a quasi-plane IW front for a horizontally inhomogeneous ocean.
