Pourquoi c'est important
The World Meteorological Organization (WMO) has issued a report stating an 80% probability of El Niño developing between June and August. El Niño is a natural climate phenomenon characterized by rising sea surface temperatures in the central and eastern equatorial Pacific, which alters global weather patterns.
總部設於瑞士日內瓦的聯合國世界氣象組織（WMO）今天表示，6月至8月間出現聖嬰現象的機率高達8成，這將增加極端天氣事件發生的風險。
聖嬰現象是一種自然氣候現象，會讓中部及東部赤道太平洋的海面溫度升高，導致全球的風、氣壓及降雨型態發生變化。這種現象通常每2至7年發生一次，每次持續約9至12個月。
世界氣象組織在最新的「聖嬰/反聖嬰現象」季報中表示，11月以前聖嬰現象出現的可能性「接近或超過9成」，大多數預測模型顯示，這次聖嬰現象「至少為中等強度，而且可能達到強烈程度」。
世界氣象組織秘書長索羅（Celeste Saulo）指出，全球必須為聖嬰現象做好準備，因其可能會「加劇乾旱及豪雨，並增加陸地和海洋出現熱浪的風險」。
世界氣象組織說，即使是中等強度的聖嬰現象，也會讓某些極端天氣和氣候事件更有可能發生。
