Figure 15: Regression patterns for SVD1 with the SST time series for a) panel 1: SST ($^\circ$C), values exceeding 0.4$^\circ$C are hatched; b) panel 2: $\nabla \cdot {\bf F_A}$  ($W m^{-2}$), values exceeding 8 $W m^{-2}$ are hatched (positive) or stippled (negative); c) panel 3: precipitation (mm/day), values exceeding 0.8 mm/day are hatched (positive) or stippled (negative); and atmospheric diabatic heating, values exceeding 8 $W m^{-2}$ are hatched (positive) or stippled (negative). The zero contour is omitted in all plots, negative values are dashed and the zonal mean is given at right.
