Abstract
Ejection and sweep eddy motions are coherent structures in the atmospheric surface layer. These structures are responsible for surface-layer fluxes of sensible heat and momentum. This study analyzes these structures over the same surface in short and tall grass situations. It is shown that momentumsweep eddy motions are dominant in both short and tall grass situations. Theratio between eddy structures revealed that the small-scale eddies are activatedin tall grass conditions. The study applies to unstable conditions duringdaytime.
