Latest Text Summary



During the second dekad of August, the general position of the ITF slightly withdrew from its previous position in early August, but remained above-average in latitude compared to climatology. The mean western portion of the ITF (10W-10E) was approximated at 20.4 degrees N, nearly 1 degree above the normal climatological position (19.5) for mid-August. The anomalously high position in the west was associated with strong southerly flow, advecting moisture and triggering well-distributed rainfall across much of the northern Sahelian regions of Mauritania, Mali and Niger. The mean eastern portion of the ITF (20E-35E) was approximated at 16.8 degrees North, remaining below the normal climatological position (17.4) for mid-August. Much of the ITF suppression was located over much of Sudan. Figure 1 illustrates the current position of the ITF relative to its climatological position during the second dekad of August, and its previous position during the first dekad of August. Figures 2 and 3 are time series, illustrating the mean latitudinal values of the western and eastern portions of the ITF, respectively, and their evolution since April, 2015.
