Sensitivity of GPS tropospheric estimates to mesoscale convective systems in West Africa

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 9541-9561 (2019)

This study analyzes the characteristics of GPS tropospheric estimates (zenith wet delays – ZWDs, gradients, and post-fit phase residuals) during the passage of mesoscale convective systems (MCSs) and evaluates their sensitivity to the research-leve

Regional co-variability of spatial and temporal soil moisture–precipitation coupling in North Africa: an observational perspective

Autor: I. Y. Petrova, C. C. van Heerwaarden, C. Hohenegger, F. Guichard

Publikováno v: Hydrology and Earth System Sciences, Vol 22, Pp 3275-3294 (2018)

The magnitude and sign of soil moisture–precipitation coupling (SMPC) is investigated using a probability-based approach and 10 years of daily microwave satellite data across North Africa at a 1° horizontal scale. Specifically, the co-existence

Autor: F. Couvreux, E. Bazile, G. Canut, Y. Seity, M. Lothon, F. Lohou, F. Guichard, E. Nilsson

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 8983-9002 (2016)

This study evaluates the ability of three operational models, with resolution varying from 2.5 to 16 km, to predict the boundary-layer turbulent processes and mesoscale variability observed during the Boundary Layer Late-Afternoon and Sunset Turbu

Parameterization of convective transport in the boundary layer and its impact on the representation of the diurnal cycle of wind and dust emissions

Autor: F. Hourdin, M. Gueye, B. Diallo, J.-L. Dufresne, J. Escribano, L. Menut, B. Marticoréna, G. Siour, F. Guichard

Publikováno v: Atmospheric Chemistry and Physics, Vol 15, Iss 12, Pp 6775-6788 (2015)

We investigate how the representation of the boundary layer in a climate model impacts the representation of the near-surface wind and dust emission, with a focus on the Sahel/Sahara region. We show that the combination of vertical turbulent diffusi

Revisiting historical climatic signals to better explore the future: prospects of water cycle changes in Central Sahel

Autor: C. Leauthaud, J. Demarty, B. Cappelaere, M. Grippa, L. Kergoat, C. Velluet, F. Guichard, E. Mougin, S. Chelbi, B. Sultan

Publikováno v: Proceedings of the International Association of Hydrological Sciences, Vol 371, Pp 195-201 (2015)

Rainfall and climatic conditions are the main drivers of natural and cultivated vegetation productivity in the semiarid region of Central Sahel. In a context of decreasing cultivable area per capita, understanding and predicting changes in the wat
