| Resumo | The last few years witnessed a lively discussion about the meteorological impact of the observed smoke from Amazonian forest fires along the smoke plumes. It seems that biomass burning aerosol impact on cloud formation and microphysical processes may be of importance mostly at the end of the dry season and beginning of the wet season. The aim of this study is to analyze daily and weekly historical rainfall time series for stations located along the smoke plume over Southern Amazonia in search of trends that could be attribute to biomass burning effects. Daily rainfall time series longer than 30 years of records for August- September from four rainfall gauges distributed around southern Amazon basin are analyzed. During the earlier part of the record, biomass burning was not extensive as opposed to the later part of the record. The Empirical Mode Decomposition (EMD) and their related marginal spectrum are used to determine oscillatory components of the rainfall variability that would help finding possible mechanisms related to large scale global circulation or to the impact of the smoke from Amazon fires on rainfall. An interesting observation made in this regard that shed some light on the way precipitation pattern has behaved in terms of both the wet spells and the frequency intensities from small to intense ones, along the period studied, is the strong inter-annual modulation. The cumulative rainfall during the two months of each year along all the recorded data shows similar pattern. Other analyses reveal a rather low reliability of rainfall in all the rainfall stations and in both months August and September. The oscillatory components of the monthly rainfall reveal common features of inter-annual variability. The first mode appears as a mixture of quasi-biennial oscillation and frequencies related to the ENSO phenomenon. Other modes are related to the quasi-decadal and bi-decadal oscillations. The slowest varying mode (residue) seems to represent the rainfall long term trend. With exception of Jaraguá in September, the rainfall trend for all the rainfall stations and in both months August and September is positive. Notwithstanding the small number of stations utilized in the analysis, the results indicate that, if biomass burning smoke effects are present in Southern Amazonia at the end of the dry season inhibiting rainfall, those effects may be masked by large scale controls over rainfall producing mechanisms. That would call for detailed experimental plans to single out the possible effect of smoke on rainfall over Amazonia. | |||
