When El Nino occurs the trade winds tend to weaken. Also water from the western Pacific moves to the Eastern Pacific.

∙ 11y agothe pacific trade winds weaken or reverse during a el nino storm THIS ONLY OCCURS IN THE PACIFIC!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

El nino develops because of a weakening of what?
Trade winds.
Do plate tectonics effect el nino?
It decreases trade winds
What happens when increased air pressure causes trade winds to lesson?
When increased pressure causes trade wind to lessen, El Nino is formed. El Nino is caused by high air pressure in the South Pacific that causes trade winds to die out. This causes the waters to warm up, which causes more rain in Latin America.
What are some of el nino's effects on land and sea?
Some of El Nino's effects on land and sea include long-lasting drought, a significant increase or decrease in thunderstorm activity, and below normal hurricane activity. The warming of the Pacific ocean as a result of weakening trade winds causes El Nino.
What does upwelling have to do with el nino?
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.

What weather system might be occuring if the trade winds in the pacific are stronger than normal?
la Nina

Which statement describes sea surface temperatures along the South American coast and Pacific trade winds during El Nino?
The answer that best describes this is.... the sea surface temperatures become warmer than normal; and Pacific trade winds are from the west!
What does upwelling have to do with el nino?
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.
WHAT IS THE CAUSE OF EL NIÑO?
Weaker winds means the ocean gets warmer and this process happens interchangeably and consecutively thus making the El Niño bigger and bigger. In other words, El Niño is caused by the weakening of the trade winds which results in pushing of warm surface water to the west and less cold water to the east.
How do scientists tell when an el nino will occur?
Scientists can tell when an El Nino will occur if in the tropical Pacific Ocean, a network of buoys will indicate a change in temperature, currents and winds in the equatorial band. These collected data are evaluated by a computer designed to predict El Nino.
Is El nino caused by the change of currents?
In a way, yes. El Nino - which is the warm phase of the oscillation known as El Nino Southern Oscillation - begins to get going when the atmospheric circulation in the equatorial Pacific breaks down, which causes the prevailing Trade Winds from the east to weaken or reverse. Then, wind from the west pushes warmer water from the Western Pacific to the east and up against the coast of South America, thereby changing surface currents.
What unusual events occur during el nino?
warm water flows from western pacific toward south America
