Amazon River Discharge and Its Relationship with the Precipitation
[28-Aug-2018] Jiang, Y.
Presented at the 2018 Ocean Salinity Science Team and Salinity Continuity Processing Meeting
The Amazon river discharges about 15% of all the fresh water into the oceans by all the rivers of the world. Seasonal fresh water discharge from Amazon river is shown by the lower sea surface salinity (SSS) plume in the Atlantic Ocean. Both RSS SMAP SS v2.0 Level 3 dataset and Tropical Rainfall Measuring Mission (TRMM) Precipitation dataset spanning from 2015 to current are used for the analysis and comparison. SSS average from 55°W to 45°W in longitude and from 2°S to 10°N latitude region presents the seasonal variation with lowest SSS around summer and maximum around winter season which is lagged by about three months from the TRMM precipitation average data.
