In an article in Climate Dynamics entitled "Recent summer precipitation trends in the Greater Horn of Africa and the emerging role of Indian Ocean sea surface temperature", CHG researchers continue to examine the effects the warming Indian Ocean has on precipitation in the Greater Horn of Africa.

This paper follows a previous CHG paper "A westward extension of the warm pool leads to a westward extension of the Walker circulation, drying eastern Africa", also published in Climate Dynamics. Park Williams answered some questions about the paper here.
