Abstract
The suitability of shipboard profile measurements of mean
temperature, mean humidity and mean wind over the open ocean is
examined on the basis of six hours and 20 minutes of simultaneous
profile measurements made from the R/V Acania on 20-21 September
1973 near San Nicolas Island, California. Comparisons of the
profiles obtained from the shipboard measurements, as well as the
meteorological parameters derived from those profiles are made
with results obtained from more stable platforms. Parameters
examined include the Richardson number, the friction velocity,
the drag coefficient and the roughness length.
The drag coefficient and roughness length were found to be
generally larger than those obtained from more stable platforms,
but the Richardson number and the relationships between the
various parameters, as well as the profiles of wind speed and
temperature themselves, compare favorably. The results indicate
that a ship can be a suitable platform for measuring profiles.
