Fig. 3: Spatial pattern of zonal and meridional advection and respective components.

Breakdown of zonal (a–d) and meridional advection (e–h) into the respective components (Eqs. (5) and (6)) for AAPM and BAPM. Stippling represents values significant at 95% using a two-tailed t-test. Contours show the horizontal advection term (L.H.S of Eq. (4)) from −30 to 30 W/m2 in steps of 10. solid contours show a positive tendency and dashed contours show a negative horizontal advection. Refer to Supplementary Fig. 14 for scaled version of the figure.
