Theoretical and Applied Climatology Aims and scope Submit manuscript

Summary

Monthly and annual climatic variabilities of precipitation were analyzed from a 60 years record of rainfall data at 10 measuring stations in the humid region of Argentina.

Different statistical techniques were used to analyze the regional homogeneity of precipitation fields. Special structures and monthly trends were studied. Simple correlations of yearly precipitation at different locations were computed. Exponential functions relating cross-correlations and distances were determined through regression analysis.

Monthly and annual rainfall show no evident signs of trends; aleatory processes are predominant in the whole region; and, correlation functions are independent of the direction of the vector connecting the stations.
