| Résumé anglais |
It has become fashionable to provide explanations for droughts in the Sahel. However, such a major climatic change extends far beyond the African context and could only relate to broader meridional patterns of general atmospheric circulation. The cooling of the Arctic has increased the strength of the moving polar highs and increased the dynamism of the northern meteorological hemisphere, causing the southwards migration of the whole of the tropical rain-bearing structures over a distance of 200-300 kilometres.
