CLIMATE IMPACT PREDICTIONS
Long-range climate outlooks for southern Africa since 1991
Prof Mark R Jury
A strong La Nina has developed in the Pacific, so conditions favour
above normal rainfall across Southern Africa. The Atlantic west of
Angola has a weak signal, but the Indian Ocean east of Tanzania, shows
reduced convection which supports above normal rainfall over Southern
Africa in the December to March season. The main regions expected to
receive above average rainfall are Namibia, Botswana, and South Africa
excluding the Limpopo area. Zimbabwe may only receive normal rains.
Temperatures over the Kalahari are expected to be below normal, so
evaporation will be reduced there, favouring crop production across
the maize belt and in western (grazing) areas.
