The reconstruction is correlated with the same atmospheric variables that influence the instrumental measurements of wet season rainfall. Anticyclonic circulation over midlatitude South America promotes equatorward surges of cold and relatively dry extratropical air that converge with warm moist air to form deep convection and heavy rainfall over this sector of the southern Amazon Basin. Interesting droughts and pluvials are reconstructed during the preinstrumental nineteenth and early twentieth centuries, but the tree ring reconstruction suggests that the strong multidecadal variability in instrumental and reconstructed wet season rainfall after 1950 may have been unmatched since 1799. #------------------- # Site_Information # Site_Name: Palestina # Location: Bolivia # Northernmost_Latitude: -15.63916 # Southernmost_Latitude: -15.63916 # Easternmost_Longitude: -62.41079 # Westernmost_Longitude: -62.41079 # Elevation: 296 #------------------- # Data_Collection # Collection_Name: BOL002 # Earliest_Year: 1924 # Most_Recent_Year: 2008 # Time_Unit: AD # Notes: #------------------- # Species # Species_Name: Centrolobium microchaete (Benth.)
