Resumen:
La Plata Basin is one of the most important agriculture and hydropower producingregions worldwide. Extreme climate events such as cold and heat waves and frostevents have a significant socio-economic impact. This work analyzes the influence ofthe surface circulation in Southern South America on daily maximum (TMAX) andminimum (TMIN) temperatures in southern La Plata Basin. A Z test for the comparisonof mean values and a Kolmogorov-Simirnov test for the comparison of distributions ofTMAX and TMIN associated with each circulation pattern were performed. Specificdaily surface circulation types are found to contribute to TMAX and TMIN anomaliesand have a predominant occurrence in the development of the extreme temperatureevents in the region. The TMAX spatial response to the regional low level circulation ismore homogenous and extended than the response of TMIN.
