Abstract


Variations in the soil temperature (TS) inside a fragment of Atlantic forest in the city of Coruripe-AL, were studied using data from a micrometeorological tower of 26 m, installed inside the forest. The data covering the year 2012 were subjected to wavelet transform. This method involves transformation of a number in a unidimensional space of time and frequency, allowing determining the dominant scales of variability and its temporal variations. The results showed that the variability of the TS region is defined by multi-scales located at certain intervals of days. However, the variability is associated with solar radiation (Rg) and precipitation.
