Abstract:: From almost 7000 near-surface eddy-covariance flux measurements over the sea, the authors deduce a new air–sea drag relation for aerodynamically rough flow: u* = 0.0583Uₙ₁₀ 2 0.243. Here u* is the measured friction velocity, and Uₙ₁₀ is the neutral-stability wind speed at a reference height of 10 m. This relation...

Abstract:: The 10-m neutral drag coefficient (C[subscript DN10]) over the sea is calculated using a large observational dataset consisting of 5800 estimates of the mean flow and the fluxes from aircraft eddy-covariance measurements. The dataset includes observations from 11 different experiments with four different research aircraft. One of the goals is...

Abstract:: The Bowen ratio, the ratio of the turbulent surface fluxes of sensible (Hₛ) and latent (Hₗ) heat, Bo ≡ Hₛ/Hₗ, occurs throughout micrometeorology. It finds application in the Bowen ratio and energy budget method, where it provides both turbulent heat fluxes when only the available energy at the surface is...

Creator:: Vickers, Dean, Mahrt, Larry, and Andreas, Edgar L.
Abstract:: Over 5000 aircraft eddy-covariance measurements from four different aircraft in nine different experiments are used to develop a simple model for the friction velocity over the sea. Unlike the widely used Coupled Ocean–Atmosphere Response Experiment (COARE) bulk flux scheme, the simple model (i) does not use Monin–Obukhov similarity theory (MOST)...
