Si bien la climatología dinámica explica satisfactoriamente los elementos del clima en ámbitos generales, un tratamiento analítico se muestra indispensable para definir los elementos resultantes de las combinaciones particulares acaecidas en cada región entre los diversos aspectos que intervienen directamente, o pueden tener influencia, en el clima local.

Although dynamic climatology satisfactorily explains climatic conditions in general environments, an analytic approach is absolutely necessary when defining conditions in a given region, and identifying the specific combination of elements that directly influences the local climate. Given that the origin and global climatic mechanisms of this transitional region have been analyzed in other studies, this paper will analyze the basic data on precipitation including regional patterns and seasonal levels. It will also include hypotheses on the functioning and calculated frequencies of this rainfall. All of this data are of undeniable value to the fields of geomorphology, hydrology, damage control and the effective human usage of available resources.
