Based on two observational data sets in China from 1956 to 2004, wind speed changes are analyzed. The annual mean wind speed (MWS), days of strong wind (SWDs), and maximum wind (MW) all show declining trends over broad areas of China. Only in the southeastern Tibetan Plateau and the ...
【解析】根据文章最后一段“Wind speed changes from time to time,depending on the time of day, weather and location.”可知,风速并不总是保持一致。故答案为speed。 Ⅷ.书面表达(20) 6月5日是世界环境日,你们学校正在开展“美丽校园,我行动”宣传活动,倡议大家制作关于创建美丽校园的主题海报。假如你是李华...
The wind speed changes in Qingdao are analyzed on the basis of annual average wind speed data from Qingdao Station from 1899 to 2015 and daily wind speed data from 88 automatic stations in Qingdao from 1961 to 2015 together with NCEP/NCAR re-analyses. The results show that in the context ...
At this point, the wind speed is between all rated wind speed and wind speed. Wind power is a program from running, wind-blade pitch angle is not adjustable. With unit speed changes of wind speed to adjust accordingly to ensure that wind is the wind factor in Cpmax Cp always, and so...

Quantifying changes of wind speed distributions in the historical record of Atlantic tropical cyclones Here we re-examine the official Atlantic basin tropical cyclone (hurricane) database HURDAT (1851–2008) and quantify differences between wind speed distri... K Chen,McAneney, J.,K Cheung - 《...
A growing literature in economics and epidemiology has exploited changes in wind patterns as a source of exogenous variation to better measure the acute health effects of air pollution. Since the distribution of wind components is not randomly distribute
Based on the historical wind data of five weather stations over the windy regions in Xinjiang,and using the homogeneous approach,the extreme climatic revolution tendencies of the wind characteristics were analyzed mainly aiming at four aspects,that is the mean wind speed,the intensity and the frequen...
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
Model predictions demonstrate that apparent frequency variations caused by changes in incoming wind speed can likely be more significant than those produced by a small damage. A technique based on principal component analysis and novelty detection is adopted to cope with this issue and its application...
