Effect of High-Frequency Sea Waves on Wave Period Retrieval from Radar Altimeter and Buoy Data
Wave periods estimated from satellite altimetry data behave differently from those calculated from buoy data, especially in low-wind conditions. In this paper, the geometric mean wave period is calculated from buoy data, rather than the commonly used zero-crossing wave period . The geometric mean wave period uses the fourth moment of the wave frequency spectrum and is related to the mean-square...
متن کاملA Comparison of Two Altimeter Wave Period Algorithms Using Data from a N. E. Pacific Buoy
Two recent algorithms for estimating zero-upcross wave periods from altimeter data are investigated using data from a buoy in the North East Pacific with a relatively high occurence of swell. Both algorithms performed well in wind seas, with low wave age, but only one – developed using a neural network – was satisfactory when the wave age was high.
متن کاملAssimilation of altimeter data in the ECMWF ocean analysis system 3
The latest version of the ECMWF ocean analysis system was recently introduced into operational use. This not only provides initial conditions for the monthly and seasonal forecast systems but also creates a historical reanalysis. For the first time, altimeter data are used in the ECMWF operational ocean analysis. However, making good use of altimetric sea level information was not easy and seve...
متن کاملTropospheric chemistry in the integrated forecasting system of ECMWF
A representation of atmospheric chemistry has been included in the Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF). The new chemistry modules complement the aerosol modules of the IFS for atmospheric composition, which is named C-IFS. C-IFS for chemistry supersedes a coupled system in which chemical transport model (CTM) Model for OZone and ...
متن کاملComparison of Kuroshio Surface Velocities Derived from Satellite Altimeter and Drifting Buoy Data
Sea-surface geostrophic velocities for the Kuroshio region calculated from TOPEX/ POSEIDON altimetry data together with in situ oceanographic data are compared with surface velocities derived from drifting buoy trajectories. The geostrophic velocities agree well with the observed velocities, suggesting that the Kuroshio surface layer is essentially in geostrophic balance, within measurement err...
