Wind driven oceanic surface waves have a major impact on marine activity, especially near the coastal regions. Strong winds associated with winter storms induce storm surges along the west coast of Japan. Combined high wind conditions, tides, and storm surges can have a tremendous impact on the surface wave fields. Accurate wave forecast becomes an important issue at various operational forecas...

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...

The study aims to determine mean annual wave heights and wind speeds in the Adriatic Sea. The Adriatic serves as a shipping route towards central Europe and a food and energy source for surrounding countries. Wave and wind climate information can serve as basis for design, research and policy making regarding ship safety and operability, potential renewable energy exploitation, design of off-sh...

The relationship between storms and extreme ocean waves in the North Sea is assessed using a long-period wave data set and storms identified in the Interim ECMWF Re-Analysis (ERA-Interim). An ensemble sensitivity analysis is used to provide information on the spatial and temporal forcing from mean sea-level pressure and surface wind associated with extreme ocean wave height responses. Extreme o...

Fast magnetosonic waves in a magnetically-dominated plasma are investigated. In the pulsar wind, these waves may transport a significant fraction of the energy flux. It is shown that the nonlinear steepening and subsequent formation of multiple shocks is a viable mechanism for the wave dissipation in the pulsar wind. The wave dissipation both in the free pulsar wind and beyond the wind terminat...

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...

With an extended mapping approach and a linear variable separation approach, a series of solutions (including the Weierstrass elliptic function solutions, solitary wave solutions, periodic wave solutions and rational function solutions) of the (2+1)-dimensional modified dispersive water-wave system (MDWW) is derived. Based on the derived solutions and using some multi-valued functions, we find ...

The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...

The wind and wave products from the ERS mission provide an invaluable data set. This paper provides an overview of the performance of both ERS-1 and ERS-2 products on the basis of surface winds from the consistent ECMWF 40-Year Reanalysis (ERA-40), and wave fields from a long term stand-alone wave model hindcast run forced by ERA-40 winds. Furthermore, buoy and other in-situ measurements are us...

Magnetization dynamics in nanomagnets has attracted broad interest since it was predicted that a dc current flowing through a thin magnetic layer can create spin-wave excitations. These excitations are due to spin momentum transfer, a transfer of spin angular momentum between conduction electrons and the background magnetization, that enables new types of information processing. Here we show ho...
