英文摘要: Monthly wind data from 506 meteorological stations and ERA-Interim reanalysis during 1991–2015, are used to examine the surface wind trend over East China. Furthermore, combining the urbanization information derived from the DMSP/OLS nighttime light data during 1992–2013, the effects of urbanization on surface wind change are investigated by applying the observation minus reanalysis (OMR) method. The results show that the observed surface wind speed over East China is distinctly weakening with a rate of −0.16 m s−1 deca−1 during 1991–2015, while ERA-Interim wind speed does not have significant decreasing or increasing trend in the same period. The observed surface wind declining is mainly attributed to underlying surface changes of stations observational areas that were mostly induced by the urbanization in East China. Moreover, the wind declining intensity is closely related to the urbanization rhythms. The OMR annual surface wind speeds of Rhythm-VS, Rhythm-S, Rhythm-M, Rhythm-F and Rhythm-VF, have decreasing trends with the rates of −0.02 to −0.09, −0.16 to −0.26, −0.22 to −0.30, −0.26 to −0.36 and −0.33 to −0.51 m s−1 deca−1, respectively. The faster urbanization rhythm is, the stronger wind speed weakening presents. Additionally urban expansion is another factor resulted in the observed surface wind declining. © 2017, Springer-Verlag Berlin Heidelberg. Citation statistics:
