Spatial variation in the topoclimate scale average temperature at municipalities of São Carlos do Ivaí and Floraí-PR

Abstract

The temperature shows a temporal and spatial variability throughout the day, month and year, with a very important climatic element to be analyzed and spatialized. The mapping of the thermal conditions of a given region is an indispensable factor in agro-climatic studies, but what we see is a lack of research due to lack of data record. Considering this issue is that it aimed to conduct an analysis of the spatial distribution of monthly mean air temperature in the range topo-climatic for the municipalities of San Carlos do Ivai and Florai, Northwest of Paraná State. The method adopted in this work is based on estimates of monthly normal temperature with altitude and latitude with the use of linear regression equation proposed by Pinto and Alfonsi (1974). To prove the method was also applied to the linear Pearson’s correlation coefficient, to determine the association degree of the data obtained with the application of the equation and those provided by a climate reference station closest to the area of ​​research. The results showed that the method is efficient and can be applied to assess the spatial distribution of monthly temperature, correlated with the topography, providing a detailed analysis of the study area and enabling thus its applicability in different sectors of the economy, mainly in agricultural planning.
