| Summary: | In the situation of low-carbon energy development， photovoltaic power industry develops rapidly， and photovoltaic power stations in China are mostly built in the Northwest Gobi region.In order to study the influence of Gobi photovoltaic power station on local climate and environment， this paper compared and analyzed the characteristics and differences of meteorological elements between the Gobi photovoltaic power station and the reference station in December 2019 and April， July and October 2020.The results show that the temperature of PV power station at 2 m height is lower than the reference point in all seasons at night， and the cooling effect weakens with the increase of height.The temperature of PV power station is higher than that of the reference site at 2 m height in the daytime of spring， summer and autumn， but lower than that of the reference site in the daytime of winter.With the increase of height， the warming effect weakens in spring and summer in daytime， and strengthens in autumn and winter.Because the specific heat capacity of photovoltaic panel is lower than that of soil， the temperature of photovoltaic panel is higher than the surface temperature of reference station in daytime， and the difference increases with the enhancement of solar radiation.Compared with the reference station， the wind direction in the photovoltaic power station is single and the wind speed is lower due to the shielding effect of the photovoltaic array on the wind.With the increase of height， the influence of pv array on wind field decreases. |
