Answer:
El Niño generally causes irregular water cycles in the Americas and high temperatures in Australia and Asia.
Step-by-step explanation:
El Niño is a global phenomenon occurring in the ocean and the atmosphere. El Niño and La Niña are large temperature fluctuations in the surface waters of the tropical Pacific Ocean, whose effect is great on the climate of the southern hemisphere.
It is a complex climate fluctuation between ocean and atmosphere that arises from ocean currents and atmospheric circulation. It is the most extensive and well-known interannual variation in weather and climate in the world, and occurs every two to seven years. Not all areas of the world are affected, but El Niñom is felt in the Pacific, Atlantic and Indian Oceans.
In the Pacific, warming under an El Niño extends throughout the tropical Pacific, and there is a clear correlation with the intensity of the southern oscillation. While El Niño events occur at about the same time in the Pacific and Indian Oceans, they do not occur until 12 to 18 months later in the Atlantic. Its appearance displaces precipitation zones eastward in the Pacific Ocean and prevents the rise of cold water along the coast of South America, which cuts off the source of nutrients for the fauna of these waters and considerably harms the fishing industry.
