The Effects of Anthropogenic Heat Release on Urban Meteorology and Implication for Haze Pollution in the Beijing-Tianjin-Hebei Region

Table 1

Statistics for the observed and simulated daily mean wind speed at 10 m (WS10), temperature at 2 m (T2), and relative humidity at 2 m (RH2) in Beijing (BJ), Tianjin (TJ), Tangshan (TS), Tanggu (TG), and Baodi (BD) during January 2013. COR: correlation coefficient; MB: mean bias; NMB: normalized mean bias; bc: base case; c1: case 1.
