Abstract: This paper investigates the parameterization of rainfall interception by a vegetation canopy in GCMS. Recent land surface schemes have introduced canopy water balance equations, which include sub-grid scale rainfall ...

Abstract: Via its impact on surface fluxes, subseasonal variability in soil moisture has the potential to feed back on regional atmospheric circulations, and thereby rainfall. An understanding of this feedback mechanism in the climate ...

Abstract: This paper examines observational evidence of a positive feedback between the land surface and rainfall in semiarid conditions. The novelty of the work lies in the length scale of study, investigating interactions between ...

Abstract: The Hydrological Atmospheric Pilot Experiment in the Sahel (HAPEX-Sahel) was designed to investigate land?atmosphere interactions in the semiarid conditions of southwest Niger. During the intensive observation period (IOP) ...

Abstract: Recent observational studies have suggested a role for soil moisture and land?atmosphere coupling in the 15-day westward-propagating mode of intraseasonal variability in the West African monsoon. This hypothesis is ...

Abstract: The surface fluxes of heat and moisture in semiarid regions are sensitive to spatial variability of soil moisture caused by convective rainfall. Under conditions typical of the Sahel, this variability may persist for several ...

Abstract: oil moisture plays a fundamental role in regulating the summertime surface energy balance across Europe. Understanding the spatial and temporal behavior in soil moisture and its control on evapotranspiration (ET) is ...

Abstract: A critical function of a land surface scheme, used in climate and weather prediction models, is to partition the energy from insolation into sensible and latent heat fluxes. Many use a soil moisture function to control the ...
