The results of measurements of the fluxes of momentum, moisture and sensible heat in the marine boundary layer are described.
Two techniques for obtaining the fluxes are discussed. The fluxes
of these quantities are most directly obtained by the eddy correlation
method, that is, by measuring the fluctuating vertical and downstream
velocity (w and u), temperature (T) and humidity (q)
and computing the covariances wu, wT and wq. The fluxes are
also computed by obtaining a measure of the energy dissipation rate
from second-order structure functions and relating the dissipation to
the production of energy. To use the dissipation methods, values of
universal inertial-convective subrange constants (Kolmogoroff constants)
are required. Kolmogoroff constants are computed from second and third-order structure functions.
Most of the data were collected on R.V. FLIP during BOMEX
(Barbados Oceanographic and Meteorological Experiment) and during
a pre-BOMEX trial cruise near San Diego. A small amount of additional
data was collected from a site at South Beach, Oregon.
The value of the Kolmogoroff constant for velocity is consistent
with other recent observations. The temperature and humidity constants
are found to be equal within the measurement error and have
values of about 0.8. The two methods for computing the fluxes agree
on average for momentum and moisture flux. The two methods do
not agree for sensible heat flux during BOMEX although there is fair
agreement for the San Diego data. / Graduation date: 1972
