摘要：This study analyzed the frequency and intensity of absolute minimum temperatures associated with atmospheric systems in the Central Southern Paraná State. It was selected the municipalities of Guarapuava, Palmas, and Irati to represent the area, both considering the location and the available database. Daily temperature data provided by Agronomic Institute of Paraná (IAPAR) and National Meteorological Institute (INMET) and satellite imagery provided by Technological Institute of Paraná (SIMEPAR) were analyzed in the winter seasons from 2004 to 2012. Data of temperature were tabulated in Microsoft Excel and satellite imagery was analyzed through videos produced in Windows Live™ Movie Maker®. The highest influence of polar air masses (mPa and mPp) was prevalent, but the continental tropical mass frequently affected the study period, by reducing the surface cooling for several days. Keywords: air masses, negative temperatures, geographical climatology.
