Abstract: Observations of two low-level frontal passages by a hot-wire anemometer placed at 3 m above the ground provide evidence that frontal zones and the postfrontal regions exhibit enhanced kinetic energy dissipation. These ...

Abstract: Very little is known about the nature of turbulence in the transition zone of a synoptic-scale cold front, especially at the dissipative scales. Lacking this knowledge, accurate models of surface frontogenesis are compromised. ...

Abstract: Large-eddy simulation (LES) results indicate that turbulent scalar diffusion in the convective atmospheric boundary layer (CBL) has interesting properties. A scalar introduced into the bottom of the CBL with no flux through ...
