Weekly Introduction:
Update Of ITCZ

During the period from August 21-31 2004, the African portion of the ITCZ moved dramatically to the south in the eastern half of the continent. During the past dekad, the eastern region of the ITCZ moved from around 19N to around 15N. This contrasts with the movement in the west where the ITCZ moved relatively little from last period and is located very close to the 1988-2003 climatological mean. The southward movement of the ITCZ at this time is quite normal as the normal northward peak occurs during the second dekad of August.
