description

6 pages; International audience; Les montagnes tropicales sont souvent perçues comme des sentinelles des changements climatiques. Pour autantles variations climatiques interannuelles à décennales sont-elles le reflet de celles des espaces environnants ? A l’échelle del’Afrique au sud du Sahara, une analyse de la variabilité des pluies entre 1941 et 2000 montre une cohérence spatiale peudiminuée par les reliefs. Des exemples sont présentés de reliefs constituant même des révélateurs de la dynamiqueatmosphérique et de la variabilité climatique d’échelles larges.
