Urbanization Effects on Surface Wind in the Guangdong-Hong Kong-Macao Greater Bay Area Using a Fan-Sector Method.

ABSTRACT: Surface wind directly affects human life, wind energy utilization, the atmospheric environment, and many other aspects. The Guangdong-Hong Kong-Macau Greater Bay Area (GBA) megalopolis is experiencing an accelerated progress of urbanization, which may result in the change in surface roughness and atmospheric characteristics. In this study, urbanization effects on surface wind speed (SWS) in the GBA megalopolis, particularly Zhuhai, is investigated by using long-term automatic meteorological measurements, ERA5 reanalysis, and nighttime light data. Results of the analysis show that the averaged SWS has decreased significantly at a rate of -0.53 m s-1 per decade over the past decades. With the help of observation-minus-reanalysis (OMR) method, which excludes the atmospheric circulation effect
