This is an objective analysis of upper level divergence and convergence.  This figure shows the 250 hPa winds and areas of upper divergence (yellow contours) and convergence (magenta contours).  Note the areas of upper divergence along and east of the northern hemisphere trough as it extends to Suriname and French Guiana.  The southern hemisphere trough, clockwise rotation along 43W, also shows an area of divergence to the east of the axis, as expected/suggested by the subjective analysis.
