The diagnosis of B5 related to the EMI index, anomalous relative vorticity advection transported by basic meridional wind (vector: basic meridional wind, unit: ms⁻¹; shading: , unit: 10⁻¹¹ m⁻¹·s⁻¹). The vorticity perturbation is the regression coefficient of the vorticity regression on the standardized EMI index. The dotted areas are through the 90% confidence t-test.
