Analysis and evolution of climatic dynamics during last fifty years in Sicily
In the last years the Wavelet Transform has received a lot of attention for the ability to provide a time-frequency representation of analysed signals in the time domain. Such an advanced time-frequency analysis has been effectively applied in various fields, such as, for example, geophysics, astrop...

Such an advanced time-frequency analysis has been effectively applied in various fields, such as, for example, geophysics, astrophysics, telecommunications and climatology. The paper reports the results of the time series of temperature of some Sicilian weather stations.
