摘要：Figures See all figures Authors Samuel Louvet , Yves Richard , Bernard Fontaine Centre de recherches de climatologie (CRC), Faculté des sciences Gabriel, 6, boulevard Gabriel, 21 000 Dijon Key words: Africa, western, climate, disease outbreaks, seasons, rain Page(s) : 95-100 Published in: 2005 Numeric models in general circulation produce climate output fields on too coarse a grid. Some indicators show great local variation according to their environment (such as relief or vegetation). This is the case for precipitation, especially when, as in Africa, it is primarily convective. The methods and tools allowing effective cross-use of these two types of information range from nested models to statistical models and include mixed approaches. These techniques, still under development, are necessary to correctly conduct impact studies related to short- or intermediate-term climatic variability, especially as it affects the extension of vector-borne diseases.
