Quantification and interpretation of the climate variability record

摘要: Abstract The spectral view of variability is a compelling and adaptable tool for understanding the climate. In Mitchell (1976) seminal paper, it was used to express, on one graph with log scales, very wide range climate variations from millions years days. approach particularly useful suggesting causal links between forcing response variability. However, substantial degree intrinsic Earth system may respond external in complex manner. There has been an enormous amount work over last decades. Hence this we address question: Can (after 40 years) update diagram provide better interpretation? By reviewing both extended observations available such new methodological developments study interaction internal forced timescales, give positive answer question. addition, review alternative approaches decomposition pose some challenges more detailed quantification
