aThe corresponding extreme wind speeds at the wind turbine positions at hub height are calculated by the WindSim CFD model by the speed-up factors between the wind speed at the wind turbine positions and the Alino mast position. The results can be seen in Table 12. 对应的极端风速在风涡轮位...
The buoys measure either significant wave height (Hs), wind speed at the height of the anemometerz(Uz) or both. For wind speed, a consistent reference height of 10 m is required (U10). This was obtained by assuming a neutral stability logarithmic boundary layer as given by1: $${U}_...
Based on the data from 27 meteorological observing towers over South China for one year,it is found that the average wind power density index is less than the three-fold wind speed index.The variation law between annual mean wind and shape parameter with height and a new method for estimating...
Satellite observations of the ocean surface provide a powerful method for acquiring global data on wind speed and wave height. Radar altimeters have now been in operation for more than 25 years, providing a reasonably long term data set with global coverage. This paper presents data from a full...
The rated wind speed time histories with 600 s used in both the two scenarios and generated using the program TurbSim [62]. Figure 5 gives the wind speed time histories with the average wind speed rated speed at the hub height (Vhub = 11.4 m/s). For the rated wind speed, the ...
The wind field at the center of the potential developing area (PDA) was measured as a function of wind direction, with an increment of 22.5° (16 wind directions in total). Within each test direction, mean wind speed and turbulence intensity were obtained at 9 height levels corresponding to...
Satellite altimetry missions have provided continuous Significant Wave Height (SWH) and Wind Speed (WS) data over the global oceans spanning for more than two decades. The successful launch of SARAL/AltiKa (referred as simply AltiKa hereafter) on February 25, 2013 operating at Ka-band (35.75 ...
