For this purpose, the linkage of the spring SPI time series with the winter North Atlantic Oscillation (NAO) and the sea surface temperature (SST) was investigated by means of maps of the correlation coefficient for the period from October 1910 to September 2004. The results indicate that the winter NAO is a good predictor for the SPI6 of the spring (SPI6 finishing in April, May and June, SPI6 April , SPI6 May and SPI6 June , respectively) for the northern, central and southern regions of Portugal. The winter SST1 (area of the Mediterranean Sea) must only be considered for the northern region, and the winter SST3 (area of the North Atlantic between Iberia and North America) only for the southern region. Spatial maps of predictive SPI6 for April, May and June were created and validated. The neural models explained more than 81% of the total variance for the SPI6 April and SPI6 May and more than 64% of the total variance for the SPI6 June. Probability maps were also developed considering the values predicted by the neural methods for the spring months and all drought categories (moderate, severe and extreme). These maps indicating the probability of droughts can provide valuable support for the integrated planning and management of water resources throughout Portugal.

Specifically, the concept of we question the concept of experience, which in contemporary philosophy was valued and incorporated keynote object in the research of philosophy of education, by its importance no development of sensitive educational practices, who value personal expression, the uniqueness, diversity and transculturation, which can be herself possibility, creation, invention, event, poetic. We refer our thoughts especially in Larrosa (2014), Pagni and Gelamo (2010), Barbosa (2006, 2010), Aguirre (2009), Masschelein (2008). The present research is methodologically in the survey and bibliographical analysis, in the context of a qualitative approach. Consider, by way of conclusion, that the knowledge of experience can enhance the human dimension of education in favor of a creative teacher, and ethics.
