The process known as Ekman transport is caused by right-angle winds along a shoreline. The surface water is replaced by deep, colder water from offshore.
They are both wind driven, if the Ekman Transport is moving in towrds the shore then downwelling will pull water from it and move it down and out. While when the Ekman Transport is moving out away from shore up welling will pull water up and feed the Transport. Note all directions are based on 90 degrees to the left or right fo the wind direction depending on wich Hemisphere.
Upwelling is weaker during a normal pattern El Niño event. This is because El Niño brings warmer sea surface temperatures, which suppress the nutrient-rich cold water that drives upwelling along the coast. In contrast, La Niña events typically enhance upwelling due to cooler sea surface temperatures.
Cold currents near coastlines often indicate the presence of upwelling. This is because upwelling brings cold, nutrient-rich waters from the ocean depths to the surface, leading to colder surface currents. Some examples of cold currents near coastlines that are associated with upwelling include the California Current, the Benguela Current, and the Canary Current.
Geostrophic flow works in opposition to Ekman transport in a gyre. Geostrophic flow is the balance between the pressure gradient force and the Coriolis force, causing water to move at an angle to the wind direction. This balances the net transport of water caused by Ekman transport.
El Nino reduces upwelling. Normal sea surface temperatures in Pacific tend to be warmer in the west because of upwelling, where warm water flows west because of trade winds and colder water rises up to replace the warm water in the Eastern Pacific. During El Nino, the trade winds get all screwed up and warm water is spread out more evenly in the Pacific. So there is less upwelling and the Eastern Pacific sees warmer sea water.

Yes, but one type only: equatorial upwelling!There are three types of upwelling: equatorial, coastal, and seasonal.Equatorial upwelling is caused by the winds known as the trade winds. The trade winds blow from east to west in the vicinity of the equator. On the northern side of the equator Ekman Transport is to the right (northward), and on the southern side it is to the left (southward). With water flowing directly away from the equator, both northward and southward, the equator itself has a deficit of water. Hence, water from below upwells to fill in the gap. Equatorial upwelling is most prominent in the Pacific Ocean.
