Fig. 7From: Subinertial frequency variations in the axis of the Tsugaru Warm Current east of the Tsugaru StraitWavelet transform of the axis of the Tsugaru Warm Current at 141.3°E calculated from a the high-frequency radar data and b the JCOPE-T DA data. The yellow line indicates the inertial frequency at 41.5°N, 1.26 cycles per day (periods of 0.75 days). The blue and black lines denote 1 and 0.07 cycles per day (periods of 1 and 14 days), respectivelyBack to article page
