The Niger River Basin Moisture Sources: A Lagrangian Analysis

The Niger River basin (NRB) is located in the important climatic region of the African Sahel. In this study we use the Lagrangian tridimensional model FLEXPART v9.0 to identify and characterise the moisture sources for the NRB. This method allows the integration of the budget of evaporation minus precipitation over 10-day backward trajectories, thereby identifying the origins of the air masses ...

Atmospheric rivers: a mini-review

*Correspondence: Luis Gimeno, EPhyslab, Departamento de Física Aplicada, Universidad de Vigo, Campus As Lagoas, 32004 Ourense, Spain e-mail: [email protected] Atmospheric rivers (ARs) are narrow regions responsible for the majority of the poleward water vapor transport across the midlatitudes. They are characterized by high water vapor content and strong low level winds, and form a part of the ...

How Do Atmospheric Rivers Form?

Toward a Fully Lagrangian Atmospheric Modeling System

An improved treatment of advection is essential for atmospheric transport and chemistry models. Eulerian treatments are generally plagued with instabilities, unrealistic negative constituent values, diffusion, and dispersion errors. A higher-order Eulerian model improves one error at significant cost but magnifies another error. The cost of semi-Lagrangian models is too high for many applicatio...

Chattahoochee-apalachicola Rivers Water Quality Sampling a Lagrangian Sampling Project

The field work portion of this project began September 22, 2012, with an expected completion date of November 10, 2012. The field work will involve traveling by canoe down the entire Chattahoochee-Apalachicola River system from the source spring near Chattahoochee Gap to the Gulf of Mexico, collecting water quality data, documenting illegal incursions into the river channel, and gathering such ...
