Latest Text Summary



From April 1 - 10, 2015, the ITF moved northward across Africa and approached its climatological position. The mean western portion of the ITF was located ay 10.9 degrees N, while the long-term average was centered upon 11.5 degrees N during this time of the year. The anomalous position of the ITF over the western portion could be attributed to stronger than normal northerly flow during the period. Conversely, the mean eastern portion of the ITF was located slightly to the north at 8.9 degrees N relative to the mean position, which was located at 8.8 degrees N. This was partially due to vigorous southerly flowi, which brought abundant rains over parts of Eastern Africa. Figure 1 shows the current position of the ITF relative to the climatological position during the first dekad of April. Figures 2 and 3 are time series illustrating the mean latitudinal values of the western and eastern portions of the ITF, respectively, and their evolutions since April.
