On the Role of Wind–Evaporation–SST Feedbacks in the Subseasonal Variability of the East Pacific ITCZ

Time evolution of (a),(b) cross-equatorial SST gradient, anomalous SLHF gradient, and gradient of dynamic component of SLHF; (c),(d) cross-equatorial SST gradient and gradient of thermodynamic component of SLHF; and (e),(f) cross-equatorial SST gradient, (SST − T₁₀) gradient, and zonal wind shear (100 m minus 10 m) gradient for (left) nITCZ and (right) dsITCZ events. All gradients are computed between the northern and southern latitudes highlighted in Figs. 4a and 4b.
