| Resumo | The Amazon Basin (AB) is dominated by tropical rainforest and is considered as one of the major continental region of active convection. The convection over the AB is modulated by various physical processes and circulation features in different space-time scales. One of the problems in study the rainfall variability over AB is related with its continental characteristic, which can result in biased analyses for rainfall variability over the AB. The present study is motivated by two scientific issues. One pertains to the rainfall spatial regionalization, based on gridded daily rainfall data for the period of 1979 to 1993, and other to study the time-scales variability of indices representative of each region. The rainfall regionalization was carried out by the "K-means" method of cluster analysis, and the wavelet analysis (WA) and Empirical Mode Decomposition (EDM), among others are used to study the time series index of each region. From the cluster analysis, it was found that there are five regions with peculiar characteristic of annual cycle and daily PDF. Four of these regions are distributed in the NW-SE direction, and one is around the Amazon River mouth (ARM). A rainfall index based in the regional mean submitted to wavelet analysis shows dominant intra-seasonal oscillation in time scales of 20-30, 30-45 and 45-75 days. These intra-seasonal oscillations rarely occur at the same time in all the regions, with exception of the western and northern regions, where the 30-45 day oscillation takes place more frequently between October and December. A key distinction of rainfall variability among these regions at inter-annual scales can be observed in both the EMD analysis and the spectral analysis of the regional rainfall index. The EMD revels that the modes are quite different in each region. Two regions located at western and northern of the basin show similar slower mode with positive trend, the two southern regions present slower mode oscillatory with maximum (minimum) in 1981-83 (1986-1987). In the ARM region, this mode represent negative trend. The MEM spectral analysis shows peaks at the range of 3-5 year in all the indices probably related to the ENOS phenomenon, and quasi-biannual oscillation are observed in the western and northern regions. Also, the western region presents a quasi-decadal oscillation. Besides, in the western region the highest rainfall amounts are observed. That appears to be the region where the rainfall modulation is more complex. The ENSO phenomenon appears to have different effects on the seasonal precipitation in each region, and as an example the PDF of the daily rainfall of the ENOS (1983) is analyzed. Analyses for anti-ENSO (1989), and a normal year (1981) show that the impact of this phenomenon is greater in western and the ARM region than in the other. | |||
