Fig. 2: Evolution of the annual maximum and minimum values and seasonality for Amazonia precipitation, Amazon river discharge, and Amazon plume region (APR) ocean salinity.
From: Amplified seasonal cycle in hydroclimate over the Amazon river basin and its plume region
a Amazonia precipitation during the period 1979–2018. b The seasonality of Amazonia precipitation (maximum minus minimum values) during the period 1979–2018. c, d, e, f, and g, h are similar to a, b, but for Amazon river discharge and APR ocean salinity, respectively. Note that ECCO4 salinity data only cover the period 1992–2017; GECCO2 the period 1979–2016; and SODA3.1.3 the period 1980–2015. The solid (dashed) lines are the linear fits used to determine the trends.
