Applying them to data referring to the temperatures of the surface of sea (TSS) in coast of Brazil, in the oceanic and coastal zone between Cabo Frio-RJ and Cabo Santa Marta-SC.

Data for analysis

The Kullback-Leibler distance and the measure of the entropy of a system has been efficient in the analysis of data. In this article we make a revision of these concepts associating them it an amplitude grating. From Kullback-Leibler distance we can esteem the divergence of a fdp in relation to the Gaussian model, that presents an excellent distribution of probabilities. When is necessary to investigate the behavior of a system regarding its organization, a good tool is the measure of the entropy, that it shows how much a system is “ordened” or “disordered”. The objective of this work is apply the cited methods above to analyse the data referring the temperature of the surface of the sea (TSS), that had been acquired by orbital sensor AVHRR (Advanced Very High Resolution Radiometer) installed on board the North American satellites of series NOAA. The temperatures had been measured in areas located in the Southeastern coast of Brazil, in the oceanic and coastal zone between Cabo Frio - RJ and Cabo Santa Marta - SC. We choose different localization in function of the oceanographical characteristics of the interest regions. About the organization of this article, initially is presented some preliminary concepts and information. To follow we approach the methodology
