Abstract
This study aimed to analyze the trends of eleven indices of climate extremes depend on daily precipitation for the state of Amazonas, dividing it into four mesoregions, as well as, to evaluate its relationship with SST anomalies in the Pacific (ENSO) and Atlantic (Atlantic Dipole) Oceans. The daily rainfall data for the period 1970-2010 were derived from INMET. Data of monthly anomalies of SST in the Tropical Oceans were obtained from CPC / NOAA. The results show that in the state of Amazonas is not possible to affirm categorically that there was an increase or decrease of extreme precipitation events in recent decades. Furthermore, it was found that the SST in the equatorial Pacific and Atlantic Tropical Oceans showed statistically significant correlations with indices of extreme precipitation. Thus, it is possible states that SST anomaly in these areas has an influence on precipitation rates in the state of Amazonas.
