Caracterização de forçantes naturais do clima por meio da informação mútua da temperatura do ar em diferentes estações meteorológicas de Mato Grosso

Abstract

The general objective of this research was to characterize the natural forcing of the climate through mutual information of air temperature in different meteorological stations in Mato Grosso. Air temperature data from a long time series (between 1998 and 2020 years) was analyzed, calculating the degree of correlation between data from pairs of stations was assessed using the mutual information coefficient, totaling 55 analyzes of pairs of stations. From the results generated, the dependence of the mutual information coefficient on the distance between stations was studied. Using the theoretical results predicted by classical transport theory, considering the phenomena of molecular transport, convective and turbulent transport, the experimental results demonstrated that there is no significant influence of heat transport between the evaluated locations, that is, that the thermodynamics of the region is dominated by radiation.
