摘要	The inverse cascade flux of kinetic energy (KE) and its length scale in the South Indian Countercurrent (SICC) region were investigated using 24-year satellite altimeter daily data from 1993-2016. The evolution of the eddy life cycle in the SICC was presented systemically. It was found that the arrest and inject scales of inverse cascade were within the baroclinic most unstable scale and observed energy-containing eddy scale. The seasonal cycle of the arrest scale, inject scale, and amplitude of the inverse cascade were compared with the eddy kinetic energy seasonal cycle, which revealed a 1.5-month lag of the eddy kinetic energy to the vertical shear of zonal velocity, implying the existence of nonlinear processes during the eddy growth phase. Meanwhile, the anisotropy of the inverse cascade indicated that kinetic energy might be transferred from meridional motions to zonal motions, which is probably caused by beta effect. These results would be beneficial for a better understanding of the KE transfer processes in the SICC region.
