Abstract: In this paper we propose to study the cross-correlation between the air temperature and the air relative humidity using the DCCA cross-correlation coefficient ρDCCA. We choose four cities (meteorological stations) located in the State of Bahia (Brazil), as our case study. Our data were available hourly from the Brazilian Institute of Meteorology. Accordingly, in addition to showing that the variables have a negative cross-correlation, we present a new vision about these variables, producing the detrended cross-correlation contour map. As a result, we can see (or not) islands of cross-correlations, that depend on the local time and also the time scale involved.
