Energy spectra in geophysics : climate

A composite of temperature spectra shows three regimes corresponding to the weather, macro-weather and climate [Lovejoy and Schertzer, 2014] | Information^[1]

A composite of temperature spectra shows three regimes corresponding to the weather, macro-weather and climate [Lovejoy and Schertzer, 2014] | Information^[1]

The above temperature spectrum shows that there exists three scaling regime over different range of scales (time) which corresponds to different regime (weather, macro-weather and climate)
