The Africa portion of the ITCZ during the period from April 11-20 2006 was located near 10.23 degrees north latitude when averaged from 15W-35E, compared with the long term 1988-2005 mean of around 11.24 degrees north. The current versus mean situation can be seen in Figure 1, and it may be noted that the current ITCZ exhibits a strong southward bias compared to the climatological average.

Precipitation in the region follows the discontinuity location fairly well during the current period, with an overall lack of rains in northern Nigeria, CAR, and southern Sudan. Portions of southern Mali saw unusually heavy rainfall during the period. In the west (from 10W-10E), the current ITCZ was located near 11.8N, compared with the long term mean of 12.5 during the same dekad. Much of this bias is seen east of the Prime Meridian, especially over Nigeria. In the east (from 20E-35E), the current ITCZ position is near 8.0N, compared with the long term mean of Round 9.9 degrees north. Additional information may be found at

During the period from July 21-31, 2009, the African portion of the Intertropical Front (ITF) was located near 17.2N degrees, while the normal for this time of year is 18.2N

In the east, from 20E-35E, the ITCZ was located near 13.9N, compared with 13.5N for the mean, and 13.4N for last year

Contributing to the rapid northward movement of the discontinuity, a strong frontal system pushed through the Sahel during the week, bringing enhanced southerly winds and

During the period from June 11-20, 2005, the African portion of the Intertropical Discontinuity was located at approximately 16.0 degrees north latitude when averaged over the ten

In the west the ITF is less suppressed with a historical average position of 16.2N, compared to the current of 15.3N

Figure 1 shows the current position compared to normal, and it is apparent from this diagram that the ITF continues to be significantly suppressed across most of Africa, but it

In the west, the latest position of the ITCZ was near 13.7N, compared to the climatological mean of 14.6N and that during May 1-10 of 15.8N

From May 11-20, 2005, the African portion of the Intertropical Discontinuity was located near 12.4 degrees north latitude, compared to the climatological mean of 13.4 north and

The current position corresponds to the accumulated dekadal rainfall well, especially in the east where the ITCZ seems to have taken a slight jump to the north (Seen in figure 1)

Examining figure 3 which depicts the ITCZ vs normal for the area of 20-35 degrees east, it is seen that after beginning the season well south of normal, the ITCZ has rapidly
