Abstract
Numerical simulation on thermal environment was performed around Shanghai, the largest commercial and industrial city in China A meso-scale meteorological model improved by the authors was applied to around Shanghai, covering the 140km×124km areas divided by 2km grid cells. The results showed that heat island intensity around Shanghai might reach 3°C at 15:00 and 2°C at 21:00 in calm and fine summer days. Simulations indicated that energy savings are available and helpful to urban thermal environmental mitigation; however, vegetation is more attributable to mitigation of urban heat island.
