Abstract

The municipality of Maringá, 23°27' S and 51°57' W, lies in the north State of Paraná, southern Brazil. Pronounced atmosphere variations are due to alternations in tropical and extra-tropical atmosphere systems. Daily variations of surface climate factors in Maringá and their relationships with atmospheric systems which cause different types of weather during autumn and winter of 1996 have been investigated. The relationship between the activities of the Atlantic Polar Front (APF) and local rainfall has also been analyzed. The year 1996 has been chosen because of the absence of the El Niño and La Niña phenomena. The analysis was based on the dynamic concept of climate and on the rhythmic analysis methodology. Results show that during the period under analysis rainfall has been directly or indirectly an APF-caused result. Rainfall has been more related to the duration of front systems than to the number of occurrences of these systems within the region. Low temperatures were chiefly caused by the incursions of interior polar systems and, as a rule, when fronts failed to cause any rain.
