Changes in absolute vorticity (10−5 s−1) for each sensitivity experiment relative to the PI reference simulation for the TC season in the NH (JASO) and SH (JFMA). The contour intervals (dashed, negative anomalies; solid, positive anomalies) follow the color bar scale. Only values that are significantly different at the 5% level using a local (grid-point) k-s test are shaded. The 0-anomaly line is omitted for clarity.
