IMPACT OF A LOW-LEVEL JET DECAY ON TURBULENCE STRUCTURE AND FLUXES

Low-level jets are a prominent feature of the nocturnal boundary layer often modulating turbulence properties throughout the boundary layer and near the surface. Jet decay is one aspect of jet dynamics that has received little attention. This study explores the jet decay and the influence on boundary layer properties. Particular interest is paid to cases that influence the morning transition. The impact on turbulence properties and fluxes of energy, heat, and CO2 will be examined using eddy-covariance data.
