Application of the cross tab analysis to the spatial analysis of climatic tendencies in the eastern sector of Spain

Abstract

We suggest cross-tab analysis to study the spatial distribution-overlapping trend between climate elements. We present two examples of such overlapping, in which we compared the spatial distribution of annual rainfall trend with spatial distribution of trend of maximum daily event and spatial distribution of annual rainfall variability. In the first ones (Comunidad de Valencia, E of Spain) we find a complex relationship between annual rainfall trend and daily maximum rainfall trend. In the second ones (Depresión del Ebro, NE inland of Spain) the relationship between annual rainfall trend and annual rainfall variability trend suggest that futures scenarios could be more and more non-predictable.
