El niño大气海洋作用以外可能诱因的定量对比
首发时间:2009-07-02
摘要:由于海洋和大气是易变的,仅靠它们难以解释El Niño在过去百万年尺度上的相对稳定性,因为其间地球气温的明显变化与El Niño的相对稳定性是不协调的。这意味着,某些稳定的外部影响因素,施加在开放的海洋和大气的非线性运动上,形成了在外部影响因素周期附近摆动的El Niño变化的2至7年周期带。对功率谱、小波的分析表明,El Niño周期带不是由Volcano、solar、greenhouse gas、tropospheric、LOD、Sun Spots引起的,还没有发现合适的外因解释。

The Quantitative Contrast Between the El niño and External Influence Factors Beyond the Sea and Atmosphere
Abstract:It is difficult to explain the continual or ‘‘permanent’’ of irregular cycle of El Niño by only the changeful sea and atmosphere, as the change of atmosphere temperature was inconsistent with El Niño in the past 5 to 3 million years. This implies that there are some external influence factors with relative stable change cycles which drive the changeful sea and atmosphere to some irregular 2 to 7 years especially the about 4 year cycles. Also, the 2 to 7 years cycle band should be around the relative stable change cycles of external influence factors. The spectra and wavelet analyses show that the volcano, solar, greenhouse gas, tropospheric, LOD, Sun Spot are not the stable external influence factors.
Keywords: El Niñ o global change external influence factors
