Figure 2
From: Surface frontogenesis by surface heat fluxes in the upstream Kuroshio Extension region

Seasonal variation in SST, MLD, net surface heat flux, and surface heat flux term. Latitude-time plots of (a) SST (in °C), (b) MLD (in m), (c) net surface heat flux (in W m−2), and (d) surface heat flux term in Eq. (1) (in °C month−1) for the 145°E–150°E band. Also drawn are absolute values of the meridional SST gradient (contours, in °C °latitude−1). The contour interval is 0.9 (0.3) °C °latitude−1 for thick (thin) contours. The figure was prepared with GrADS v.1.9b4 (http://cola.gmu.edu/grads/).
