摘　　要：北太平洋对北极的半封闭状态和南太平洋对南极的开放状态是厄尔尼诺事件发生的构造基础,强潮汐导致南北半球之间的流体对流和北太平洋海洋热能周期性向南太平洋输送。日、地、月和行星相对位置的变化决定了潮汐的强度,其变化规模与全球气候变化周期相对应。强潮汐加大垂直方向和水平方向海水的混合,使西太平洋和北太平洋暖水变冷,使东南太平洋冷水变暖,形成厄尔尼诺事件。行星冲日、近地潮、日月大潮、日食、月食的叠加所形成的强潮汐与厄尔尼诺事件发生时间有非常好的对应关系。The North Pole is semi-blocked to the north Pacific Ocean and the South Poleis open to the South Pacific Ocean, which is the tectonic basis for El Nino events, strong tides makes the thermal energy flow from North Pacific Ocean to South Pacific Ocean. The alterative alignmentof the earth, moon, sun and planets give rise to the gradual changing in the strength of tides which has the same timescale as the global climate cycle. The strong tides result in the increasing of vertical and horizontal mixing of water in the ocean, which drawing the warm Pacific water from north/west to the south/east, where it warms the atmosphere above and makes El Nino occur in the whole world, this is the reason why strong tides are concerned with El Nino event.
