英文摘要 | Given the considerable influences of urbanization on near-surface air temperature (T-a) and surface skin temperature (T-s) at local and regional scales, we investigated the biogeophysical effects of urbanization on T(a)and T-s in the Beijing-Tianjin-Hebei (BTH) region of China, a typical rapidly urbanizing area, using the weather research and forecasting model (WRF). Two experiments were conducted using satellite-derived realistic areal fraction land cover data in 2010 and 1990 as well as localized parameters (e.g. albedo and leaf area index). Without considering anthropogenic heat, experimental differences indicated a regional biogeophysical warming of 0.15 degrees C (0.16 degrees C) in summer T-a (T-s), but a negligible warming in winter T-a (T-s). Sensitivity analyses also showed a stronger magnitude of local warming in summer than in winter. Along with an increase of 10% in the urban fraction, local T-a (T-s) increases of 0.185 degrees C (0.335 degrees C), 0.212 degrees C (0.464 degrees C), and 0.140 degrees C (0.220 degrees C) were found at annual, summer, and winter scales, respectively, according to a space-for-time substitution method. The sensitivity analyses will be beneficial to get a rough biogeophysical warming estimation of future urbanization projections. Furthermore, a decomposed temperature metric (DTM) method was applied for the attribution analyses of the change in T-s induced by urbanization. Our results showed that the decrease in evapotranspiration-induced latent heat played a dominate role in biogeophysical warming due to urbanization in BTH, indicating that increasing green space could alleviate warming effects, especially in summer. |
