On the 3rd local time, the World Meteorological Organization (WMO) issued a report stating that the El Niño phenomenon has appeared in the tropical Pacific, and it is expected to increase rapidly in the next few months, leading to the possibility of extreme weather events such as heat waves, droughts, and heavy rainfall in many parts of the world.

The World Meteorological Organization predicts that during the period from July to September this year, the El Niño phenomenon will develop into a strong El Niño event. The multi-model ensemble forecast shows that the sea temperature in the equatorial Middle East Pacific will rise significantly. It is expected that the El Niño phenomenon will continue to strengthen in the autumn of the northern hemisphere. The impact will extend to multiple regions around the world.

WMO Secretary-General Shaulo said the organization is strengthening the coordination of climate information services and early warning support to help governments, humanitarian agencies, climate-sensitive sectors such as agriculture and health, and vulnerable communities prepare for potential impacts.

El Niño is also a source of atmospheric heat, pushing up global temperatures and changing weather patterns around the world. Expert analysis pointed out that higher ocean temperatures can keep the atmosphere warm for a long time, provide additional energy for storms and increase evaporation, thereby increasing the possibility of extreme precipitation and floods. Ocean warming will also cause sea level rise and ice melting, and put pressure on marine ecosystems.

In addition, higher sea surface temperatures are also associated with more frequent and intense marine heat waves, that is, abnormal increases in ocean temperature will not only damage ecosystems and fisheries, affect coastal economies, but may also exacerbate extreme heat weather in adjacent land areas.
