ROBLEDO, Federico A.  y  PENALBA, Olga C.. Seasonal analysis of daily frequency and extreme intensity of precipitation in the Southeast of South America. Meteorologica [online]. 2007, vol.32, n.1-2, pp. 31-49. ISSN 1850-468X.

In this paper the climatology of the different components that composed the monthly rainfall was actualized and extended. For this purpose, we calculated the frequency of daily rainfall and the mean daily intensity for the second half of the century. 58 stations were used for this study. In addition we calculated the climatology for the daily extreme rainfall and its intensity, defining different thresholds according to the regions. Between November and March, we observed two  centers (65º W  -25º S and 45º W  - 22º S) with more than 50% of days with daily rainfall above 0.1 millimeters (mm) , and lower values in the rest of the region. Spatial patterns and seasonal variation of daily rainfall above 75th percentile show similar patterns. Nevertheless, mean daily intensity increased respect to 0.1mm threshold. The centre 45º W - 22º S, in summer, takes values of 36 mm/day and 20 mm/day in winter and 36 mm/day (8 mm/day) in the northeast of Argentina in summer (winter). In the center east of Argentina the intensity of the extreme rainfall exceeds 32mm/day (20mm/day) in summer (winter).
