Vertical distribution of the energy conversion rate calculated from the JCOPE-T DA data during 2019 (upper row: potential energy; middle row: kinetic energy) and their ratio (that of potential energy to that of kinetic energy, lower row) in each season at 41.6°N. Black contours denote the potential density anomaly, σθ. The green line denotes 141.3°E (see Additional file 1: Fig. S5)
