Fig. 4: Net primary production low frequency variability and ocean circulation.

From: Future changes in atmospheric synoptic variability slow down ocean circulation and decrease primary productivity in the tropical Pacific Ocean

Fig. 4

a Correlation coefficient between net primary production (NPP) and Tropical Cells (TC) Index (11 years running mean) (see “Methods”). b Time series of NPP (black) and TC index (11 years running mean) in the region (180°E–100°E, 10°N–10°S). c, d Similar to (a, b) but considering subtropical cells (STC). e, f Similar to (a, b) but considering mixed layer depth (MLD). The experiment analyzed is CTL (see Table 2). The region 180°W–100°W, 10°N–10°S is considered in (b, d, f).
