Statistical Characterization of Zonal and Meridional Ocean Wind Stress
(American Meteorological Society, 2005)Four years of ocean vector wind data are used to evaluate statistics of wind stress over the ocean. Raw swath wind stresses derived from the Quick Scatterometer (QuikSCAT) are compared with five different global gridded ... -
A Dissipation Function for the Internal Wave Radiative Balance Equation
(American Meteorological Society, 2005)The radiative balance equation describes the evolution of the internal wave action density spectrum n (k) in response to propagation, generation, nonlinear transfer, dissipation, and other processes. Dissipation is assumed ... -
Impact of Combining Temperature Profiles from Different Instruments on an Analysis of Mixed Layer Properties
(American Meteorological Society, 2005)For a joint analysis of temperature profiles from floats, expendable bathythermographs (XBTs), and other instruments (e.g., thermistor chains) the consistency of the profiles from the different sources needs to be ensured ... -
A Preoperational Scheme for Calculating Sea Surface Height by Bernoulli Inverse of Argo Float Data in the North Atlantic
