             abstract = "It is important to understand the past coastal climate to evaluate 
                         the future coastal climate, in order to evaluate impacts of 
                         climatic changes. European Union financed a project to produce 
                         data for the past climate (hindcast) using atmospheric models and 
                         of wave models for the region of Europe. This project is 
                         concentrated for the region of Ireland where the results of a GCM 
                         were refined by a limited area atmospheric model to produce winds 
                         with high resolution. Those winds were used by a wave model from 
                         which wave heights and other relevant information were produced. 
                         The project produced an atlas of winds and of waves from 1958 to 
                         1997. It is important these data are evaluated at the 
                         spatio-temporal domain. However such evaluation produced by 
                         conventional statistics do not produce satisfying results, due to 
                         the non-linear and asymmetry of the data. This work uses the 
                         Gradient Pattern (GPA) technique to characterize the evolution of 
                         spatial-temporal patterns of winds and waves. It is based on two 
                         computational operators: AAF (Asymmetric Amplitude Fragmentation) 
                         that allows to obtain a measure of asymmetry of a dynamic pattern; 
                         and CEF (Complex Entropic Form), which allows to observe 
                         intermittent patterns during the spatio-temporal evolution. In 
                         this analysis, we apply the operators AAF, producing the first 
                         gradient moment (g), and CEF, producing the fourth gradient moment 
                         (in particular, the phase, \Φg4) in a part of this hindcast 
                         (1988-1997) to detect patterns of medium and small scales.",
