TL;DR: In this article, a theory appears to be in place to predict humidity in the free troposphere if winds are known at large scales, providing a crucial link between small-scale behavior and large-scale mass and energy constraints.

TL;DR: In this paper, the relationship between the spatial organization of deep convection and the large-scale atmospheric state was investigated by using several satellite datasets and reanalyses, and by defining a simple diagnostic of convective aggregation.

TL;DR: The AMMA (African Monsoon Multidisciplinary Analysis) program is dedicated to providing a better understanding of the West African monsoon and its influence on the physical, chemical and biological environment regionally and globally, as well as relating variability of this monsoon system to issues of health, water resources, food security and demography for West African nations.

TL;DR: In this paper, a simple conceptual model of the sources and sinks of humidity is used to reconstruct, using a backward Lagrangian trajectory technique, the water vapor distribution in the tropical and subtropical free troposphere.

TL;DR: In this article, a meteorological benchmark is set up with ground-based observations from the African Monsoon Multidisciplinary Analysis (AMMA) program, and a novel methodology is introduced that accounts for the errors associated with the areal-time rainfall averages.
