The utility and shortcomings of near-real-time ocean surface vector wind retrievals from the NASA Quick Scatterometer (QuikSCAT) in operational forecast and analysis activities at the National Hurricane Center (NHC) are described. The use of QuikSCAT data in tropical cyclone (TC) analysis and forecasting for center location/identification, intensity (maximum sustained wind) estimation, and anal...

Nuclear energy sources have been widely used in the past decades in order to power spacecraft subsystems. Nevertheless, their use has attracted controversy because of the risk of harmful material released into the atmosphere if an accident were to occur during the launch phase of the mission, leading to the general adoption of photovoltaic systems. As compared to solar cells, wind turbines have...

Due to the lower efficiency and the larger wind direction error of traditional algorithms, a novel integrated wind retrieval algorithm is proposed for conically scanning scatterometers. The proposed algorithm has the dual advantages of less computational cost and higher wind direction retrieval accuracy by integrating the wind speed standard deviation (WSSD) algorithm and the wind direction int...

Definition Wind is air in motion and is basically a vector quantity with a magnitude (speed) and a direction. Ocean surface stress is another vector quantity closely related to wind; it is the turbulent transfer of momentum between the ocean and the atmosphere. Their different applications are summarized in the section "Scientific Significance".

HF radar can be employed to measure sea surface state parameters such as waveheight, wind field and surface current velocity. This paper describes the application of the high frequency ground wave radar in remote sensing the surface conditions over the Eastern China Sea in October, 2000. The radar, referred to as the OSMAR2000, was developed by Wuhan University. Preliminary wave spectra, wavehe...

Wind, wave and current interactions control the boundary fluxes, momentum and energy exchange between the atmosphere and the ocean, and within the water column. The wind wave effect on the circulation is investigated in a threedimensional time-dependant ocean circulation model. This POM (Princeton Ocean Model) based model is implemented with realistic coastlines in South China Sea and emphasize...
