This article reports the characteristics of multiple time scales of signals, evapotranspiration (ET) and outgoing long-wave radiation, in the eastern Amazonia. This has to apply the technique of mathematics Morlet wavelet transform. The results show a difference in the time scales between intraseasonal, synoptic and mesoscale for events. For the non-flooded event (13 September 2004), hourly fluctuations in ET in scales from 2 to 5 h were more intense than those in the case of the flooded event (9 April 2005). This can be related to mesoscale circulations, possibly caused by local surface conditions, such as Lake Breeze.
