Linear and Nonlinear Baroclinic Instability of the Northern Hemisphere Winter Zonal Flow
Publisher: American Meteorological Society
Abstract: This study was carried out to investigate the extent to which the results of linear ?- or f-plane solutions for baroclinic instability of simple flows can be applied to the Northern Hemisphere winter, zonal mean zonal flow. ...
The Effect of Fetch on the Directional Spectrum of Celtic Sea Storm Waves
Publisher: American Meteorological Society
Abstract: This paper describes measurements of the directional spectrum of storm waves obtained using the PISCES high-frequency radar. The storm occurred during the Netherlands UK Radar Wavebuoy Experimental Comparison 2 experiment ...
Limits to the Inversion of HF Radar Backscatter for Ocean Wave Measurement
Publisher: American Meteorological Society
Abstract: The power spectrum of backscatter from the ocean surface at HF radio frequencies is characterized by two large peaks called the first-order Bragg peaks. These are surrounded by a continuum due to second-order effects. The ...
Shortwave Direction and Spreading Measured with HF Radar
Publisher: American Meteorological Society
Abstract: he accuracy of wave direction and spreading at the Bragg-matched wavelength measured with HF radar over a wide range of HF operating frequencies is demonstrated by comparison with buoy data. The agreement for shortwave ...
Signal Sampling Impacts on HF Radar Wave Measurement
Publisher: American Meteorological Society
Abstract: Averaging is required for the measurement of ocean surface wave spectra and parameters with any measurement system in order to reduce the variance in the estimates. Sampling theory for buoy measurements is well known. The ...
Spatial Averaging of HF Radar Data for Wave Measurement Applications
Publisher: American Meteorological Society
Abstract: F radar data are often collected for time periods that are optimized for current measurement applications where, in many cases, very high temporal resolution is needed. Previous work has demonstrated that this does not ...
Factors Affecting the Accuracy of SHOWEX HF Radar Wave Measurements
Publisher: American Meteorological Society
Abstract: Ocean Surface Current Radar (OSCR) HF radar measurements of ocean waves and currents were made during the Shoaling Waves Experiment (SHOWEX) in the fall of 1999. During some periods, at some locations, good quality wave ...
