Figure 4 Cross sections of KA-averaged vorticity, divergence and results of the EFC budgets, where panel a depicts the averaged vorticity shaded, units: 10 -5 s -1 and divergence contours, units: 10 -6 s -1 , b total effect of rhs terms of the EFC budget equation except for RES, c averaged Lagrangian variation, d Motion-caused Flux, e Stretching, f Background Flux, g Eddy Flux, h Tilting, and i RES. The solid line in b-i is of the value 0, and all the averaged terms of the EFC budgets are in units of 10 -9 s -2 .
