different heightslong‐term changepressure gradient forcewind speedLong‐term decreasing trends of near‐surface wind speed (SWS) have been well demonstrated in China, and at the same time the factors causing the slowdown in SWS have also been explored. However, changes in wind speed and pressure...
Records include meteorological data such as wind speed at different heights/altitudes, wind direction, temperature, pressure and humidity. In order to estimate the wind speed that may occur at 61 m altitude, multilayer perceptron and radial basis function methods have been used. During the ...

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 the average wind energy density at different heights are discussed.The results show that...

Wind energy, as a renewable energy source, offers the advantage of clean and pollution-free power generation. Its abundant resources have positioned wind power as the fastest-growing and most widely adopted method of electricity generation. Wind speed st
D) currents at 10m depth (A, B) and in the thermocline (C, D) on the Equator at three locations across the Pacific Ocean indicated inFigure 5. Because the thermocline is deeper in the western Pacific, currents are presented for a corresponding depth there. Note the different speed scales...
The peak factors at different heights show a similar trend and slightly decrease with mean wind speed; average peak factors for all 10-min data from Typhoon Meari are 2.43,2.48, and 2.47, respectively. 展开 关键词: typhoon Meari wind characteristics turbulence intensity gust factor peak factor ...
Equation (2.8) is exact if the maximum shear is at z = h (which can serve as a dynamic definition of h) and if we take the velocity deep within the canopy, where the shear is small (see Fig. 2.4A), as equivalent to the free stream velocity on the low-speed side of the mixing...
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 ...
