Abstract
Propagation of Upwelling on Western-Coast Sumatera During MJO Event
Highlights
Upwelling is the movement of water masses over the surface of the sea that carry many nutrients and have a high primary fertility rate
According to Barnes (1988), this upwelling process can occur in three forms: the first upwelling that occurs at a time of deep current encounters an obstacle such as a mid-ocean ridge, where the current is deflected upwards and the water flows to the surface and upwelling caused by currents that drift away from the coast due to continuous winds over land for some time
This study aims to analyze the effect of Madden-Julian oscillation (MJO) on the propagation of coastal upwelling on the west coast of Sumatra
Summary
Upwelling is the movement of water masses over the surface of the sea that carry many nutrients and have a high primary fertility rate. According to Barnes (1988), this upwelling process can occur in three forms: the first upwelling that occurs at a time of deep current encounters an obstacle such as a mid-ocean ridge, where the current is deflected upwards and the water flows to the surface and upwelling caused by currents that drift away from the coast due to continuous winds over land for some time. This current brings the coastal surface water mass to the open seas that results in empty spaces in the coastal area which are filled with the water mass below it. Because in general the current movement always forms an angle both from and towards the sea as the effect of the Coriolis force and Ekman divergence, causing the flow of sea water away from the coastline
