Patos Lagoon
ResumoPatos Lagoon basin (in southern Brazil) has a drainage area of approximately 200,000 km2 and cover almost half of Rio Grande do Sul state. The discharge of the Lagoon is a very important environmental factor for local tourism, fisheries and navigation. To identify variability patterns of rainfall and streamflow in the Patos Lagoon basin and compare them to those found previously for Southeastern South America (SSA), data from 17 rainfall and 3 streamflow stations covering the 1978-2002 period (25 years) were analyzed. Scientific literature describes relations between interannual variability of rainfall in SSA and El-Niño/Southern Oscillation (ENSO) as well as a relationship between the Southern Oscillation (SO) and the streamflow of Negro and Uruguay rivers: lower than average in La Niña (LN) years and higher than average in El Niño (EN) years. Aproximate 3 and 6 years signals, both in the range of variability of the ENSO cycles, were identified as dominant oscillation modes for streamflow in the Uruguay river basin on interanual timescale. For PAtos Lagoon basin, the power spectral density of all series showed peaks that corresponds to periods of 3 and 4 years, in agreement with the relationships between rainfall, streamflow and the SO cited above. Spacial variability were also investigated using other stations located at Rio Grande do Sul state and Empirical Orthogonal Functions (EOF). The first and the second modes of variability are responsible for approximately 65% of the total variance. The first mode (52%) is positive for al the stations and seems to be related to the warm phase of SO (EN), which is associated to positive rainfall anomalies in southern Brazil. The second mode (13%), negative for southern stations, seems to be related to the cold phase of SO (LA - negative anomalies for the region). Applied to the streamflow stations, the EOF showed a first mode that corresponds to 88% of the total variance and is positive for the three major rivers of Patos Lagoon basin (Jacuí, Taquari and Camaquã). The power spectral density of this principal component indicated a dominant peak for approximately 4 year period, probably related to ENSO.
