Figure 6: Seasonal variations of the multicore structure in and outside the AC core.
From: Observing mesoscale eddy effects on mode-water subduction and transport in the North Pacific
The AC core is defined as the interior region enclosed by the maximum of Azimuthal speed. Proportion of profiles with vertical PV minimum in 0.05σθ bins based on Argo floats (a) in and (b) outside the AC core, with blue (magenta) bars for March–April (July–August). Results for May–June are similar to those for July–August. Vertical profiles of PV (10−10m−1s−1) and potential density (kg m−3) for (c) at CTD station at 148°E and 29.6°N on 25 March 2014, from Argo floats on 3 July, (d) in (World Meteorological Organization (WMO) ID 2901559) and (e) outside (WMO ID 2901563) the AC core. Vertical profiles in d,e are typical of multiple (single) core STMW in (outside) the AC in summer.
