Internal Tides in the Northwest Pacific Based on the Measurements at the Megapolygon Study Region


Morozov E.G.

Characteristics of tidal internal waves in the Northwest Pacific are calculated from the data of measurements of temperature and currents on a large number of moorings. Two wave systems are distinguished. One was generated to the east and southeast of the study region admittedly over the Shatsky Rise and Emperor Sea-mounts. The second system was generated in the region of the Kuril Islands. We averaged a large amount of data of measurements and calculated the ellipses of the barotropic tide currents, which appeared close to the estimates based on the satellite altimetry data. The currents of the barotropic tide were used to calculate the characteristics of tidal internal waves after subtraction of tidal currents from the data of measurements.
