Quand la route de la méditerranée transite par Dori, une ville du Sahel Burkina

Akofena, 2022
Dori est la capitale de la région du sahel du Burkina Faso, pays n’ayant aucun débouché sur la mer. Cette localité vit au rythme du passage des migrants à destination de la Lybie ou de l’Algérie via le Niger.

Local ecosystem feedbacks and critical transitions in the climate [PDF]

, 2009
Global and regional climate models, such as those used in IPCC assessments, are the best tools available for climate predictions. Such models typically account for large-scale land-atmosphere feedbacks.

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...

Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.

Climate Dynamics: A Network-Based Approach for the Analysis of Global Precipitation [PDF]

, 2013
Precipitation is one of the most important meteorological variables for defining the climate dynamics, but the spatial patterns of precipitation have not been fully investigated yet. The complex network theory, which provides a robust tool to investigate

Mapping School Accessibility in Africa: High‐Resolution Spatial Analysis Uncovers Inequalities in Education Access

Sustainable Development, EarlyView.
ABSTRACT Education is a cornerstone of sustainable development, yet large disparities in access persist across and within countries—particularly in Africa, where millions remain underserved. Among several factors influencing educational participation, physical accessibility to schools (in terms of travel time) is not comprehensively understood ...
