    Advection and its applications: Trajectories over Busia County in Kenya
    (Climate Change, 2020-12-04) Juma, G. S.; Kituni, Nebat; Makokha, John Wanjala
    Advection is defined as a conservative transport of a substance by bulk motion. The substances include pollutants, enthalpy or any material that contains thermal energy. This paper introduces the concept of advection as applied in air pollution modelling of possible pollutants using Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT). A three dimensional (3-D) advection equation is specified and a graphical output of a forward air trajectory given over Busia County. The study reveals transboundary flow of air pollutants to the Eastern parts of Uganda and across counties in Western, Central, Rift valley and Eastern Kenya respectively. An intercounty environmental monitoring policy framework is recommended in this study due to the trans county nature of air pollution issues.
