The estimation of extreme floods using long continuous simulations is linked to uncertainties which are inherent in different components of the modeling chain. The main objective of this study was to investigate the role of precipitation input data from a weather generator for extreme flood estimates. A hydrometeorological modeling chain consisting of a multi-site weather generator (GWEX) at an hourly time scale, a rainfall-ru...

Over the past decades, large variations of precipitation were observed in Africa, which often led to dramatic consequences for local society and economy. To avoid such disasters in the future, it is crucial to better anticipate the expected changes, especially in the current context of climate change and population growth. To this date, however, projections of precipitation over Africa are still associated with very large unce...

This study compares the multivariate predictions of daily temperature, temperature range, precipitation, surface wind and solar radiation of a single‐model analogue approach with an original multi‐model analogy over 12 regions in Europe and Maghreb. Both approaches are based on two‐level analogue models where atmospheric predictors are either dynamic or thermodynamic. In the multi‐model approach, independent analogue models wi...
