“The researchers, who reported their conclusions in the journal Climate Dynamics, used data spanning six decades to show that rising sea surface temperatures from emissions of human origin have created an intensification of air circulation in the Indian and Pacific Oceans, also known as the “Walker cell.”
This strengthening has caused the circulation to swell westward toward the African coast, boosting heat transfer in the atmosphere and triggering greater rainfall and cloud cover over the Indian Ocean over the past 30 years.
For East Africa, this has spelled trouble — perhaps counterintuitively.
The study finds that warm and dry winds have moved west toward Africa’s coast, inhibiting rainfall, particularly in parts of Kenya, Somalia and Ethiopia from March to June, one of the main growing seasons.”
