摘要：
The aim of this paper is to present the partial trends of rainy days and total precipitation in Cordoba Province, Argentina, during the period 1960-2010 and the full range of precipitation for the Cordoba Observatory station, which has the longest measurement record in Argentina, 1873-2010, and to show the relationship between these variables and solar activity. A strong association is shown between break points when the trend changes for both the number of rainy days and the total precipitation, and the occurrence of maxima in the sunspot cycle, indicating that these variables are modulated by the solar Hale cycle and probably by the influence of cosmic rays.
