Multi-scale fluctuations in climatic temperature variations are analyzed in She and Leveque's framework of the Hierarchical Structure model of turbulences.Through analyzing Jones'northern hemispheric monthly mean temperature series,it is shown that the hierarchical symmetry exists in climatic temperature fluctuations. We obtain a hierarchical similarity parameter β≈0.7,which is notably smaller than that for turbulent flows(β=0.8-0.9),implying stronger intermittency associated with extreme fluctuations in climatic dynamics.
