今年,气候异常波及全球,气温升高,极端天气发生频率增加。前一段时间,我国也遭遇了持续时间久、范围广的高温天气,多地的高温记录被一再刷新。这一切都可能预示着厄尔尼诺再次来临。厄尔尼诺是热带大气和海洋相互作用的产物,原指赤道海面的一种异常增温,现更多是指在全球范围内,海气相互作用下造成的气候异常。据英国《卫报》报道,目前厄尔尼诺现象形成的概率为70%。在厄尔尼诺的影响下,我国北方地区夏季容易出现干旱、高温,南方易发生低温、洪涝。对此,我们应予以足够的重视。
This year, the weather anomalies around the world, the temperature rises, the frequency of extreme weather increases. Some time ago, our country also suffered a long duration, a wide range of hot weather, many high temperature records have been repeatedly refreshed. All this could signal El Niño coming again. El Niño is a product of the interaction between the tropical atmosphere and the oceans. Originally referred to as an anomalous warming of the equatorial sea surface, more often means the climate anomaly caused by the interaction of the sea and air around the world. According to the British “Guardian” report, the current probability of El Niño formation is 70%. Under the influence of El Niño, the northern part of our country is prone to droughts and high temperatures in summer, and low temperatures and floods are easy to occur in the south. In this regard, we should pay enough attention.
