DSE date as a function of the latitudinal location of the SJSA and CIN in austral winter over southern Amazonia for the period of 1979–2011 suggests a preference of poleward SJSA and strong CIN by the delayed DSE. CIN and SJSA are first calculated using the inputs from ERA-Interim (ERAI) and NCEP reanalysis, respectively, then averaged to obtain the values shown in this figure. The triangle, square, and diamond symbols denote decadal means for the 1980s, 1990s, and 2000s. The error bars on these symbols represent the SEs with uncertainties of P < 5% (36).
