Abstract
Growth of the CBL over land in the middle of the
day has been extensively observed and relatively successfully
modeled. However the late afternoon transition
(LAT), like the morning transition, is difficult to
observe and model due to turbulence intermittency
and anisotropy, horizontal heterogeneity, and rapid time
changes. There is a striking paucity of observations of
the turbulence decay within the CBL, as well as a lack of
realistic modeling studies.
This motivated the Boundary Layer Late Afternoon
and Sunset Turbulence (BLLAST) 2011 field experiment,
which aimed at enhancing observations of the LAT, so as
to better understand the physical processes that control
it, and elucidate the role of the LAT on mesoscale and
turbulence scale motions, and on species transport.
