both the winter and summer monsoons on Beijing were weaker in the more recent of the two decades.It is suggested that the bulk of wind in Beijing is influenced considerably by urbanization,while changes in strong winds or wind speed extremes are prone to large-scale climate change in 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 - 《...
This research quantitatively recognized the wind speed change using wind speed trend and trend of wind speed variability from 1961 to 2012 and regionalized the wind speed change on a county-level basis. The mean wind speed observation data and linear fitting method were used. The findings sugge...
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
The impact of variable droop operation on two aspects of WTG operation is investigated-primary frequency contribution and smoothening power fluctuations caused due to changes in wind speed. Also highlighted is the usefulness of this control when adopted by wind farms. 展开 ...
