El Nino
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.

It causes it to stop or lessen.
Gilbert Melendez goes by El Nino, Gilbo, and El Nio.
El nino needs to be answered for real people anyway El nino mixes with upwelling and creates don't know but it can kill you
when they hit something
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.
Upwelling is when the winds cause nutrient rich waters from lower levels of the ocean to replace the surface water. Upwelling's are usually caused by coastal surges or open oceans.
Floods, mudslides, drought, and also some changes in upwelling. I know that's four but it gives more of a variety... :) hope I helped!
Under normal conditions, upwelling at the equatorial Pacific brings up nutrients from the deep ocean, which ultimate provides food for fish. During El Nino, this upwelling is reduced or even reversed, leading to fewer nutrients and thus, fewer fish.
it cause a decrease in food supply for fish
