Upwelling: the transport of deeper water to shallow levels

WebOct 20, 2014 · During El Niño years, the winds weaken, causing the upwelling of deep water to cease. The consequent warming of the ocean surface further weakens the winds and strengthens El Niño. As the ocean warms, the warmer water shifts eastward and so do the clouds and thunderstorms that produce heavy rainfall along the equator. WebThe cycles happen as an area of high atmospheric pressure over the Pacific and low pressure over the Indian Ocean change in intensity. During El Niño, the high pressure weakens and winds slacken. With less wind, there is less upwelling. Less upwelling causes less cold water and more warm water at the surface of the tropical Pacific. download driver acer aspire e1-471g
