Detailed explanation-1: -During a La Niña year, winter temperatures are warmer than normal in the South and cooler than normal in the North. La Niña can also lead to a more severe hurricane season. La Niña causes the jet stream to move northward and to weaken over the eastern Pacific.
Detailed explanation-2: -During an El Niño event, the surface waters in the central and eastern Pacific Ocean become significantly warmer than usual. That change is intimately tied to the atmosphere and to the winds blowing over the vast Pacific.
Detailed explanation-3: -El Niño is an unusually warm ocean current accompanied by heavy rains and flooding. La Niña includes unusually cold ocean temperatures that push warm surface water farther west than usual, creating the opposite effects of El Niño.
