Abstract: The climate of the West African Sahel is characterized by unusually long (multiyear) persistence of anomalously wet or dry conditions. An increasing body of evidence suggests that land surface processes contribute to this ...

Abstract: In Part I of this article we presented a study of the shortwave radiation budget in the West African Sahel, using Lettau's climatonomy model. In Part II, we apply the second of Lettau's submodels, evapoclimatonomy, to ...

Abstract: In this paper a revised verstion of Lettau's evapoclimatonomy model is used to simulate climate in West Africa. The model is applied specifically to the study sites of the HAPEX-Sahel region in Niger, an international ...

Abstract: In this paper a revised version of Lettau's evapoclimatonomy model is introduced. Climatonomy is a one-dimensional representation of mean climate, which includes a complete characterization of the surface energy and water ...
